Just use pioarduino community platform compatible with PlatformIO.
That will support the ESP32-C2

The FastLed will support the ESP32C2 Version 3.9.10

I have did a number of project using the Arduino Sd and greiman/SdFat
That supports >32GB sd cards and test on all ESP ( exspet the new ones H2/C6 )
You can have a look at the total projects ( Wifi manager, OTA updates, NTP time , and SD card , FTP Server)

I have the ESP32-C6 SDcard example working,
And I have updated the Project,
The FatEx is not working as the SdFat library is not yet( 2024-02) working under 3.0.0A version of the Arduino platform.

Has anybody got the SD-card working on the ESP32-C6.
I have it working for the esp-arduino 8266/ESP32/ESP32S2/ESP32S3/ESP32C3
Both for Fat and FatEx.
But can not get it working on ESP32-C6.
I have added the pull up and reduced the frequency

SD_PIN_SCK 21
SD_PIN_MOSI 19
SD_PIN_MISO 20
SD_PIN_CS 18 ...

I have the same problem, 1 of 3 is working correctly and 2 works but when I use the wifi then they will sometimes reboot or just stop.
I remove the EN pin and shortened the track ( so that it will not pick up noise from the RF antenna ),Did not help,
I even connected the EN to 3v3 also did not help ...

I have used a powershell script to convert the Favicon.ico ( but also HTML files )
So that i do not need to escape all type of // \\ '' and so on.
#include "IR.htm.h" // This is the file IR.htm converted in Array IR_htm
void handleRoot() {
server.send_P(200, "text/html", IR_htm, sizeof(IR_htm ...
