I'm attempting to use two PWM pins, both of different instances, to generate two signals. My current task is to synchronize these two so that one goes through a certain amount of periods while the other signal is high. Specifically, I need a 250 KHz signal to go through 256 periods while a 40 Hz signal is high for 1.05 ms and low for the other 23.95 ms. However the signals don't sync up on the oscilloscope, even though according to the math they should. Do I have to just figure out by plugging in different numbers until I find out which one works? Also, is there a way to make it so that the rising edge of the 250 KHz signal always comes a certain amount of time after the rising edge of the 40 Hz?
