i want to use a uno to control output of a 3 phase scr contolled welder.
i see two different aspects to the problem 1) read user input (required output current, mode) read feedback (output voltage and current) compare input and feedback to produce a variable that controls scr conduction angle 2)accept 3 inputs of 50hz as timing marks calculate delay required from variable above using timer or counter pulse 3 outputs to scr's
reading user input need only ocurr 10/sec, feedback 100/sec but scr pulses 300hz
the 'c' reference dosen't show direct access to timers/counters.
can i write assembler routines within 'c' sketches that i might be assured that the scr outputs run without interuption/delay?
