I want to generate with an esp32 a square signal of 1khz frequency pulses and with square pulses of 10% on and 90% off. I understand that if the frequency is 1Khz the “update_interval” parameter will be 1ms and “transition_lenght” 0.1ms:
If I mesure the voltage is 0.33V (10% of 3.3V) so I think the output is not square it seems proporcional to the brightness.t doesn’t look like a square sign
