First of all, Thank you, everyone, for your development of the UD3. I'm so excited to get mine integrated into my qcw coil.
On that note. I spoke to TMAX a while ago over email and confirmed that there is no buck ramp qcw mode currently available. Steve Ward mentioned he got "hacky" buck ramps to work on the early UD3. Is there any plan for developing buck ramp output as an alternative to phase shift? It would be great to get the arduino out of my build and just use the UD3.

Another question. Currently, I trigger my coil with an interrupter pin from the arduino. How would I go about telling the UD3 when the arudino is sending a ramp? This may become clearer to me as I mess with it, but I am still waiting on my programmer.

Thanks again for your hard work.

You could probably do your own "hacky" ramp by fiddling with the PSoC code. Likely would just need tweaking the appropriate logic schematic to output pwm for the ramp instead of a variable phase shift, plus possibly a bit of SW tweaking, but the majority of the code can probably be left as is.

We have no DAC-Channels free. I can give you a PWM output of the ramp, should be no big change.

That's a bit out of my short-term comfort zone, but maybe I can try in the future . Thanks!

That would perfectly replace my Arduino. It would also mean I don't need a wifi connection (to my Arduino) to control my ramps!
