Add initial support for ESP32-C3 #2454

misery · 2021-12-27T15:43:00Z

This is based on my other pull request for ESP32-S2: #2452
Once it is merged I will rebase this PR as it requires same changes in ESPAsyncWebServer: Aircoookie/ESPAsyncWebServer#4

Also this change requires ~~current master branch~~ version bump of:

FastLED (3.5.0) because of: Support ESP32 C3, S3 and possibly H2 variants FastLED/FastLED#1320
IRremoteESP8266 (2.8.1) because of: crankyoldgit/IRremoteESP8266@3f871e4

Work-Around for espressif/arduino-esp32#5502 in https://github.com/misery/arduino-esp32/commit/7936842c926e3af2819bcf81822d290caa07ccae

Work-Around: Remove it for now... seems the weak symbol is not included in.pio/build/esp32c3/FrameworkArduino/esp32-hal-touch.c.o at the moment.

Jason2866 · 2021-12-28T20:31:41Z

You use the old risc toolchain. Not recommended -> compiler bugs.
Actual used for core 2.0.2 is espressif/toolchain-riscv32-esp @ 8.4.0+2021r2
LittleFS is included in Arduino Core 2.0.2. No need to add as lib

misery · 2021-12-28T20:33:27Z

Thanks! I look into it tomorrow. 🙂

LittleFS is not included for S2 and C3.

I got my C3 today. Seems there is something broken.

@misery Did a complete platform build. Latest IDF4.4 and Arduino ESP32 from today.
(Includes your C3 fix too). Supports ESP32, ESP32-S2 and ESP32-C3

platform = https://github.com/tasmota/platform-espressif32/releases/download/v2.0.2.1/platform-tasmota-espressif32-2.0.2.1.zip

@Jason2866 Thank you very much! It works great! Even my C3 starts now and I can remove the work-arounds. So we can start a review now. :-)
