Once again me and chatgpt had to bump heads to make this work cause I can't code, and still credit to Finn Hammer for providing a framework with which to derive a clear concept the gpt understands better than my wording. Perhaps there is no need for the kind of complex timing math involved in this version but I just went with it. Have to be careful trying to inject too much fast math inside small interval windows because it's not hard to get the board to freeze up that way. I was mainly just trying to confirm that the waveforms I was seeing were similar enough to the ones I'd see using the ramp generator I already had using Finn Hammer's code. I don't think I could successfully use the WIFI feature on this board with the current pinout but alterations could be made. I don't really see a point though. For some kind of closed loop operation I would basically just try to compare that RC filtered signal waveform to the actual bridge power, but so far I think it's much easier to just avoid closed loop and go for a higher bus voltage head room relative to the ramp amplitude at the time.
I'm just going to make one fiber output for this generator but that's going to involve needing to add an auxiliary circuit on the driver side which gates the enable pulses relative to the burst window. I'm also playing with a SiC buck converter I might transplant into the QCWDRSSTC I'm slowly working on currently.
