On a side note, you might want to see the type of critical software I'm using with MEGA applied to extreme power electronics going up to 3 KVAR's (public) and 10 KVAR's (private). For example, in this video I'm using the four 16-bits MEGA timers, each being specifically delayed 90°, 180°, 270° with less than 62.5 ns time jitter.
P.S.1. In fact, there really SIX 16-bit timers, two of them are being emulated by my specific protoshield using some 74HCxy chips
P.S.2. You might notice from time 7min 0s in the video that actually I live update by ISR (Interrupt Software Routines) all the FOUR internal 16-bit timers register so you'll se a global frequency sweeping up. Due to the special topology of my circuit, this is equivalent to have arduino MEGA-generate phase locked 8 independent PWM rails aka 8 channel frequency generator.
Just hoping the arduino team will soon fix the USB serial issue (programming port) via a new IDE release, at least on my side I cannot afford to migrate my actual project MEGA software using very advanced timer register tricks since i'm shuttling more than 5000 VAR's with my igbt's drivers, blue smoking and $$$ gone !
Once DUE serial USB will be OK, I'll look deeper on the DUE timers which i feel from datasheet are very very interesting with fascinating new features not feasible with MEGA, same with DAC's and ADC's.
You'll notice some of my boards hosting the MEGA as piggy board are in fact fully space compatible with DUE, the board were designed more than 1 year ago betting DUE will come up.
