@seb Thanks for pointing out!

@robert-hh said in Measure Pulse width of PWM waveform: UART2 or UART3 hey, robert Thank you for reply, We will try UART for the same.

@RobTuDelft The comment in the example is wrong. Maximum is 19455. For an input value between 19456 and 19531 you'll get 19531 Hz. Generally, the precision is low at the higher frequencies. So specifying a value of 19000 give 19011 Hz, 19200 -> 19230. So it looks as if the "real" periods are multiples of a small value like 200 ns.

@cts WiPy supports a Pin interrupt, which can be triggered with the rising edge. Look in the documentation for "Pin". And is has a timer module, which could be used for setting the gate time. Look in the documentation at "Timer". However, the precision and speed is very limited. Without testing, I would assume that it works reliably only for frequencies below 1 kHz, with a uncertainty of the gate time of about 1 ms. I

@RobTuDelft 5V i use 2N7000 NMOSFET transistor for level shifting for testing for final i use smd BSS138

Thank you. I am grateful for your reply. I started to use the pin's capability of callback. It is unfortunate the pwm call is not supported yet in the documentation. What is the best way to report bugs? If this is true, it is confusing to users of Pycom.
