FastLED 3.6.0 blink sketch does not compile for an ESP32-C6 on Arduino IDE 2.3.2

[JanvidW]

I get the following error when trying to upload to an esp32 c6 dev board. I think this might be because the c6 is not currently supported?

.../FastLED/src/platforms/esp/32/clockless_rmt_esp32.cpp:349:6: error: #error Not yet implemented for unknown ESP32 target
349 | #error Not yet implemented for unknown ESP32 target

.../FastLED/src/platforms/esp/32/clockless_rmt_esp32.cpp:415:6: error: #error Not yet implemented for unknown ESP32 target

461 | #error Not yet implemented for unknown ESP32 target
| ^~~~~

The part above can be fixed by including a case for the c6 in clockless_rmt_esp32.cpp but the errors below remain

@JanvidW Would you mind trying out a fix for this problem and letting me know how it goes? I can walk you through it.

[JanvidW]

Hi Sam thanks for getting back to me, I’ll be happy to try out a fix for this.

Looks like S3 is the closest match, just with slightly different names, e.g tx_stop_chn vs tx_stop_n

Tried to hack something together #1627
