I am getting mixed answers in my searching so I figured I would ask my question directly. Irregardless of what the propeller can do as far as speed of toggling a pin, in most uses of a propeller, what is the fastest you would toggle an IO pin? For example, I know my Honda is spec'd to do 110mph, but I never need to go over 75.
I also need to answer the same question for a BASIC Stamp because my project ties into both.
In SPIN, I was able to obtain 18KHz
In PASM, I was able to obtain 5MHz as a 50% duty cycle with a XOR loop.
With Counters, I was able to obtain 60MHz through my translators which was my goal. I did go to 80, but the translators output was very unstable.
