Well start1 works with 2 stepper motors as an alternative to x2 timer interrupt and the main prog still works but not fast enough,27Hz to motors so dedicated 20x2 setfreq m64 and got 147Hz motor pulses..had to use pausus 20 or the motor stalled and whined.
High and low didn't work.
let w=timer didn't work ???
and or worked, someone posted they don't.
The "multi-tasking" stops if you use sertxd or servo,nice thought though.
Anyway I'll use the 20m2 to control my stepper motor robot and the 20x2 for the motor drive
It's got the same pwm as x2 I think.
More ram, less memory and no 12c slave,Haven't used that.
Both chips are similar.
Guess x2 is better.I only got m2's for the "multi-tasking".
