sorry for the question, I programmed esp8266 nodemcu to let out a train of pulses that I can vary based on the parameters, measured with an oscilloscope I see the square wave vary, but the frequency is always around 27 khz.
My question is:
is it possible to get a frequency of 2 khz? or the output is fixed.
Thank you
