I hope everyone is having a nice fall. I first want to say that this website is great; it is very helpful on virtually any topic! I recently finished building a FireGod system, which is an awesome design by FireGod, and I am very excited about it! I built the PC interface, one field module, and one SSRNeon design relay (sinking relay). The system works; however, it has a very noticeable flicker.
I have read through the other threads about issues with flicker, and I have tried some of the tips/tricks without success (6V regulator, etc.). I did notice some weird behavior in part of the circuit, and I was hoping that the forum might have some ideas or thoughts.
I put an oscilloscope probe on the output from the PIC to a channel and noticed something weird with the PWM signal. Every time there was a flicker, I noticed that one period of the pulse waveform would drop to zero (no pulse). Then it would go back to the normal PWM mode. This occured even if all channels were stationary. This only happens when the channel is not full on (with discrete periods) and at some intensity between 0% and 100% (or during ramping/fading). Could this be weird behavior out of the PIC? I have tried a couple different ones, and I always get some kind of flicker.
