Generating square wave fixed frequencies on 56F8xx
I am looking for any help on how to generated multiple acurate and
fixed square wave frequencies ( over 12 at once ) on the range of 4 to
9 Khz within the 56F8xx or 56F8xxxx DSC.
I would like not to use the PWM or Timers but loops and software only
and getting the outputs on GPIO A and B.
