I need some programming done for a PIC. Outline: Multiple PoL buck controllers, with power output determined by a master (Arduino) controller. A 3-phase, interleaved pulsed output with the pulse width determined by an SPI command from the master, and two analog values returned via the same SPI link. There will be multiple PICs, so addressing will need to be included in the code. The pulses will also need to be shifted slightly for successive PICs, to minimise supply noise. I really don't have a budget for this. I will take it or leave it depending on your quote. I can manage code tweaks, just not to build from scratch.

I have many years experience with designing dcdc converters and PIC microcontroller design, programming and layouts. I have also developed several distributed control applications varying in scale from multilane conveyor controller to embedded analyzers for automotive use. I am also familiar with CE certification process if you should need. I find your project interesting and believe I may be able to contribute additional benefits and insights.
