I have looked at previous questions relating to this, but none of the solutions seem to fix my problem.
I wish to drive a single servo from a ESP32 C3 Dev module.
I initially tried the generic Arduino servo.h library, but it fails to compile. I gather this chip may not work with the generic library. I have tried several other libraries, as with the same result.
The one I would really like to use (because of its elegance and functionality) is ESP32_ESP32S2_AnalogWrite, but this also will not compile. I do not even get past checking - it just returns a sizeable list of reasons for failing, but I cannot make sense of them.
I get similar messages for all of the examples sketches provided - I haven't even tried my own code yet.
The report below was attempting compile the Servo_Sweep example sketch provided with the library.
Can anyone help me, please?
