[Feature] Support for ESP32-C3

[amadea-system]

Is there any possibility we could get support for the ESP-C3? I have one these boards: https://magwled.com/products/dgrz-led-cpd-36-1-mini and I would absolutely love to be able to run this project on it.

Thanks!

Is there a schematic or a board specific pinout somewhere? Couldn't find it on their homepage.

The only specific pins I found:

• GPIO9 - Button
• GPIO20 - Serial RX
• GPIO21 - Serial TX
• GPIO2 - LED data

On the U13 block there is:

• GPIO6
• GPIO7
• GPIO10

The problem might be its a single core RISC-V one.

Unfortunately I wasn't able to find a full schematic or pinout either. The only other pin that I'm aware of is GPIO 5, which can cut power to the LED strip.

I did spend some time this weekend trying to get it to work myself, But I am far from knowledgeable w/ ESP32 development. There were a few minor changes that I had to make in the code (Add CONFIG_IDF_TARGET_ESP32C3 to the defined checks in ResetMon::getResetReasonToStr(), A type issue in AsyncClient::getNoDelay(), & another typing issue in AsyncWebSocketClient::remoteIP()). Afterwards I was able to get the firmware to compile, but the board would only boot loop.

I figured I'm missing something a lot more fundamental.

You can try this branch: https://github.com/BlueAndi/esp-rgb-led-matrix/tree/support/esp32c3

Choose the magwled-1-LED-32x8 environment and try out. Can't promise that it will work! Additional you need to change again 3rd party libs, to get it compiled.
