Je rencontre actuellement des problèmes de transmission : les données sont souvent corrompues ou incohérentes, et j’aimerais beaucoup avoir votre aide pour diagnostiquer le problème. Configuration : J’ai soudé des fils directement depuis la prise TRS vers l’ESP32. La continuité des fils a été vérifiée et confirmée. J’utilise le SDK fx-9860G de Casio. Le port série est configuré en 9600 bauds, 8 bits de données, aucune parité, 1 bit d’arrêt (8N1). Le problème : Lorsque j’envoie le message "Hello World\r\n" depuis la calculatrice, il arrive qu’il soit reçu correctement sur l’ESP32, mais la plupart du temps, les données sont brouillées ou corrompues. Voici un exemple de ce que j’obtiens dans le moniteur série : He▒▒▒▒World He▒▒ ▒▒ɱ▒5 He▒▒▒▒World He▒▒ ▒▒ɱ▒5 He▒▒ ▒▒ɱ▒5 He▒▒ ▒▒ɱ▒5 He▒▒ ▒▒ɱ▒5 He▒▒▒▒World Parfois, le message passe correctement, ce qui me laisse penser que la connexion physique est probablement correcte, mais quelque chose perturbe toujours la transmission. Mes questions : Le problème pourrait-il venir du câblage ? Est-ce que ma calculatrice pourrait avoir un défaut matériel ? Y a-t-il une erreur dans le code ou dans l’initialisation du port série ? Est-ce une incompatibilité au niveau du protocole (par exemple : niveaux de tension, stop bits, etc.) ? Et parfois, le port série refuse tout simplement de s’ouvrir, sans raison évidente. J’utilise les appels système (syscalls) listés sur cette page : https://bible.planet-casio.com/simlo/chm/v20/fx_legacy_Serial.htm Merci pour toute aide !

Est-ce que cela va être un autre fiasco comme celui du « FX-991CW », où la nouvelle version est moins bonne que l'ancienne ? J'hésite à acheter un cg50 tant qu'il est encore disponible, et je me demande si le cg50 est réellement meilleur/plus performant/de meilleure qualité, etc. que le nouveau cg100.

Tue, 29 Jul 2025 06:11:51 +0200 https://www.planet-casio.com/Fr/forums/topic18824--.html How do I use the serial communication function of the 9750giii or 9860gii? I want to create a g1a plugin to use the TRS serial port to enable the 9750giii or 9860gii to connect to the ESP32C3 for interfacing with the AI API. However, I have no idea how to develop this function using the SDK. According to the AI's prompt, it informed me of many header files that do not exist in the SDK, such as serial.h or files in syscalls.src, and I always couldn't find a way to open the serial port. Thu, 03 Jul 2025 11:13:12 +0200 https://www.planet-casio.com/Fr/forums/topic18816--.html I've been doing some development for the fx-cg50 using fxsdk/gint and it's going great so far, but I can't seem to get clangd to find the right header files. I've modified CMakeLists.txt to generate a compile_commands.json file, and added the --query-driver option for clangd to find the right compiler (sh-elf-gcc) to my neovim config. It does seem to find the compiler and most of its default header files, including gint, but I get an error where it can't find "stdint-gcc.h". Has anyone got this working in neovim (or some other editor that uses clangd as its lsp)? VSCode works fine and finds the compiler/includes no problem with the config generated by fxsdk, but I'd rather work with my usual C setup.

Tue, 17 Jun 2025 12:20:48 +0200 https://www.planet-casio.com/Fr/forums/topic18785--.html I am currently working on my add in where you are guessing a code which consists of only numbers and signs on the keyboard fxcg50. You type your code that you guessed and it causes it to appear on screen on the left hand side then if you guess the code correctly pressing EXE allows you to continue further on if wrong it causes the exact thing you typed to appear 1 line below from the right hand side just as if you were having a conversation on something like WhatsApp. However I am very confused on how to approach this. Not the guessing logic but the typing logic and also (especially the duplication part) as there are multiple ways shown on the Prizm wiki on how to "type" but confused on which syscalls to use to achieve this properly and for the duplication part. I also in my previous code have used https://prizm.cemetech.net/Syscalls/Keyboard/GetKeyWait_OS/ which I believe has some sort of affect on me pressing keys Any pointers or help to the right direction on how to carry this out would be appreciated!

The reason is that it searches only for type "Add-In", which is a type that I somehow never noticed. This probably means that all of my programs are mistyped. :sry: I'm guessing that the other types were actually meant for Casio BASIC, because add-in's came later? Would an admin be willing to change the type of the following programs to "Add-In"?
