Hi there,
SO post your code , let’s see what you missed. It should work if the pins are correct.
I would stay away from the ESP-IDF unless you want to get lost in the documentation.
Arduino IDE ver 2.0.x all work fine.
The C3 is slightly different, than the ESP32 generic so stands to reason its not plug and play code.
only the BSP’s matter when dealing with older demos. 2.0.11 and .14 are good testers. I use 2.0.11 mostly because it just works. I do update to the later ones if there’s a reason but only if it’s required for other compatibility.
