Hi, I am trying to use hardware timer to generate PPS every 1s, with 100ms pulse High and 900ms pulse low. The pulse generate at beginning of every second. I first check Martin's suggestion for interrupt each 1s . I did a little change, my code is below. Basicly, just add ROS to time message and add…

@crazymumu My apologies, the reason for the drift is because I entered the wrong values into the CC0 and CC1 registers. I've corrected the code above. It should be: TC3->COUNT16.CC[0].reg = 46874; // Set the TC3 CC0 register to generate a 1 second period while (TC3->CO…
