Using Luatos ESP32C3

Development Platforms
1

Has anyone been able to use this board with PlatformIO?

2

Have you tried using it with a regular ESP32C3 board definition already? I don’t see why this should not work.

3

I did, but apparently even the blink program didn’t work

Better use a ESP32C3 board directly like

[env:esp32-c3-devkitm-1]
platform = espressif32
board = esp32-c3-devkitm-1
framework = arduino
6 
[env:esp32-c3-devkitm-1]
platform = espressif32
board = esp32-c3-devkitm-1
framework = arduino

This option doesn’t work

7

Does uploading work, does it not work during runtime, what src/*.cpp code you have? Not enough info at all…

8

usual blink compiles, loads, but does not work

9

Well are you using the right pin? I would not rely on LED_BUILTIN to becorrect if you’re using different hardware… Hardware reference says you should try 12 or 13 as the pin.

10

I tried that, but the main error message was:
‘xtensa-esp32c3-elf-g++’ is not recognized as an internal or external command,operable program or batch file.
What do i do?

11

When I use this platformio.ini I get a perfectly normal compile…

If you get something different then your installation is broken. Remove C:\Users\<user>\.platformio and retry.

Ok i tested again now uninstalling everything of platformio and that actually worked now, help from maxgerhardt might work, but as this already worked i will stick with it
