By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Lesser General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program; if not, write to the Free Software - Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA - - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) year name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary.

Test hplp - -As root, verify that you can run test_hpcalcs. -Plug in your HP Prime to the computer and turn it on. -Wait about 10 seconds and then run: - -$ $HOME/lpg/hplp/libhpcalcs/tests/test_hpcalcs - -You should see the menu of possible operations. -If you do, hplp is working and you are successfully communicating with your Prime. - -5. Set up for normal users to access the Prime with the test software. - - a. If you are on your own isolated computer (e.g, laptop), - then add the following udev rules to the new file - /etc/udev/rules.d/82-hp-prime.rules : - - # HP Prime Calculator - SUBSYSTEM=="usb", ATTRS{idVendor}=="03f0", ATTRS{idProduct}=="0441", MODE="0666" - KERNEL=="hidraw*", ATTRS{idVendor}=="03f0", ATTRS{idProduct}=="0441", MODE="0666" - - Note that anyone on your system will be able to access your Prime with - the hplp software. - - If you are on a shared system and you want to avoid anyone accessing the - device but you, do this instead: - - # HP Prime Calculator - SUBSYSTEM=="usb", ATTRS{idVendor}=="03f0", ATTRS{idProduct}=="0441", ACTION=="add", GROUP="dialout", MODE="0664" - KERNEL=="hidraw*", ATTRS{idVendor}=="03f0", ATTRS{idProduct}=="0441", ACTION=="add", GROUP="dialout", MODE="0664" - - and add yourself to the 'dialout' group. You may need to switch to - the new group for this to work (eg: newgrp dialout). - - To activate the new udev rule, turn off your HP Prime, turn it back on, - and wait for about 10 seconds. Then, check the permissions for the device - (in /dev/hidraw? and /dev/usb/hiddev?). - - -NOTES: - * technically, compilation doesn't require being root, only the 'make install' - commands for hidapi and libhpcalcs (embedded into install_hplp.sh) require - root (and even then, only if installing to /usr or some root-only location). - install_hplp.sh cannot use sudo on its own, as it's not necessarily - configured by default. - * in the above directions, the source location to be $HOME/lpg. You may prefer - some other location, just replace $HOME/lpg by your location. - * the install prefix is forced to /usr, so that you don't have to adjust the - LD_LIBRARY_PATH environment variable, or add a line in /etc/ld.so.conf, or - add a file in /etc/ld.so.conf.d. - The install prefix is controlled by using the --prefix option to configure, - for hidapi and within install_hplp.sh. - - -Technical notes ---------------- -The code leverages HIDAPI, and it was strongly inspired by the time-proven -concepts and APIs of the libti* family, which I (Lionel Debroux) am the -current maintainer of. -The GPL'ed libti* family ( https://github.com/debrouxl/tilibs ) forms the -back-end for TILP, TIEmu, TilEm and titools (mainly), and contains the only -third-party portable FLOSS code with two-way communication support for all -three series of TI-Z80, TI-68k and TI-Nspire graphing calculators. -Putting together framework strongly inspired by libti* clearly took some work, -but having such a foundation saves time in the longer term. IOW, it's worth -the apparent complexity. - -Obviously, until the calculator's protocol is better documented, the API -will change in backwards-incompatible manners (for instance, the output -parameters of check ready and get infos operations). - - -TODO list ---------- -* ... hopefully attract _code_ contributors who have more free time than I do; -* a GUI, but I won't be the one doing it. - Nowadays, Qt is the main choice for a portable, good-looking, fast UI - toolkit (for native code programs). GTK+ used to be a better choice wrt. - portability, but that was years ago, and in 2013-2015, a number of - applications and desktop environments are switching from GTK+ to Qt. - UIs based on Web technologies are another option, Qt provides support for - those (QtWebkit / QtWebEngine) as well. -* strip out leading program metadata, if any, from .hpprgm files, like the - UTF-16LE BOM is already stripped. - Implementation notes: - * in a loop, attempt to read 4 bytes containing size, and seek forward of - that many bytes. If this leads the offset beyond EOF, break out. -* add some form of packet parsing + validation API, which can be used for - both internal sanity checking and packet dissection; -* add 39gII support, probably, as the Prime is similar to the 39gII. That's - where the usefulness of the cables / calcs separation and cables generic - API will become most obvious. - Implementation notes: - * move the upper layer from prime_cmd into a new file called by both - prime_cmd and the new file (like e.g. dusb_cmd in libticalcs). - * the 39gII has 00 00 CRC. -* modify the way recv_backup works for more reliability. - Implementation notes: - * recv_backup should attempt to receive as much data as the calculator sends, - and then split the received data. The main heuristic would be to assume - that some packets were lost, and traverse backwards the contents of the - current file to find a (00) F7 01 xx xx xx xx packet ? While this could - fail in some circumstances, it should usually salvage more data. - * recv_file shall probably be refactored as well; - * Marcus Von Cube reported that when receiving a backup fails, the test - program crashes: -" -hpcalcs INFO: prime_send_data: send remaining failed -hpcalcs ERROR: calc_prime_recv_backup: s_recv_backup failed -hpcalcs ERROR: hpcalcs_calc_recv_backup: recv_backup failed -hpfiles INFO: Displaying var entry 83EC8B55 -hpfiles INFO: Name: -" -* implement screenshot color conversion, with libpng; -* add progress feedback functionality, improved from libti*: the libti* - implementation is too complex. - Implementation notes: - * can information for current chunk of the transfer + information for the - transfer as a whole be passed through arguments of a single callback. -* add port number functionality, known from libticables, in the API. That - will enable passthrough mode for communication between real and/or - emulated calculators; -* fill in torture test; -* add two APIs for dynamically building NULL-terminated const char * arrays - from the two first columns of typesprime.c::PRIME_CONST. -* somehow gain better knowledge of the protocol, so as to be able to... -* ... add more operations and data structures. -* add dissectors and session logs, improved from libticables. - Design goals: - * make it possible to trace packet flow direction; - * make it possible to validate (sanity check) packets , to begin with... - Implementation notes: - * new APIs for registering and unregistering (multiple) callbacks; - * call the registered callbacks upon packet send and packet receive; - * leverage the packet parsing / validation code. -* add support for Prime in fake MSD mode, for firmware upgrades ?
