M5paper: source code of the default apps?
Is the source code of the default apps for M5paper published anywhere? I think that would help me understand many of the aspects.
Thank you Felix @felmue, that's very helpful.
A naive question - how can I compile that back on to the device? The only mechanism I've got working to talk to it is Arduino - I see a reference to Arduino in the .ini file, but can't open it as a project in the Arduino IDE.
Is there something different I need to open it in Arduino? Or do I need to use some different method altogether.
Thanks again for all your assistance.
for this project M5Stack engineers decided to use Visual Studio Code and PlatformIO as programming environment (instead of Arduino). Try searching with Google for
Arduino esp32 platformiofor more information.
@felmue thank you.
I've installed VS Code, and installed the PlatformIO IDE into it.
Under Devices, it can see the one corresponding to the M5paper.
Under Boards, it offers many of the M5 APIs, but M5paper isn't in the list.
I can open the "M5Paper_FactoryTest" project; it has "board" set to "m5stack-fire".
After a few false starts, it builds and installs on the device, so that's all good.
Is there anything I can/should do to set the board correctly? Does it matter?
it takes time for a new board to be included in Arduino and subsequently into PlatformIO. So when M5Paper came out the easiest way to create an M5Paper PlatformIO project, was to take a similar board, in this case M5Stack Fire, which was already available. (The key here is that both M5Stack Fire and M5Paper use PSRAM.) And later on, I guess, M5Stack engineers simply forgot to fix that.
