Multiphase Square Wave Generator
I want to produce a multiphase voltage wave using VDAC’s and Timers. The included figure shows the waveform that I’m trying to create. T1-T4 represent timings of each phase.
I’ve had some success creating the waveform using one timer, two VDAC’s, and an AMuxSeq. I used two VDAC’s and a mux in efforts to make sure the rise and fall time of the phases were sharp (this may be an incorrect assumption). My project cannot create different values for T1-T4. Should I wire 4 timers together or simply sequentially start/stop a different timer for each phase?
Can someone help me build a efficient timing scheme for creating different durations values for each phase?
