12F629 PWM usage

[mister_e]

PWM need to be finished before jumping to the next instruction. If you can deal with it, that great, unless you may need to use a Timer interrupt to produce your PWM or switch to the 12F683 which have a built-in PWM module.

Multitasking will be more than likely time slicing process, but fast enough to looks like multitasking. Once again Timer interrupts are pretty handy.

You can have a periodic timer interrupt and increase/decrease some variables in. Once you reach x value, then you enable/disable your i/os in the main program or in the ISR. But i usually prefer to do it in the mainloop when possible, keeping the ISR as short as possible.

Thanks Steve. I never thought of timer interrupts. However, I need to use the 12F629 and will try to set up some multitasking in this and let you know if I get it going.
