PIC Timer 0 calculator

With the PIC Timer 0 calculator you can see the resulting frequencies and periods when you enter three bits of information. These are :

  • Frequency (default is 4MHz).
  • Prescaler ratio.
  • Timer 0 offset.

To be honest I got fed up with looking at the data sheet to figure out the prescaler and timer offset values - this program lets you get the results easily (
There is a screenshot of the program further down the page if the runtime is not installed).
