Return value of analogWriteResolution #6

Closed ftjuh closed 3 years ago

I found that analogWriteResolution() always returns 0. According to the documentation it should return pow(2, resolution).

https://github.com/Dlloydev/ESP32-ESP32S2-AnalogWrite/blob/6474044198650928d9417d0373725ade0fdbd398/analogWrite.cpp#L244

So I assume the term should be either 1 << (resolution & 0xF); or just 1 << resolution;

Thank you for your efforts Jan

Well that shouldn't be too difficult to fix ... thanks!
