Paul and Frank,
I thought I'd try out the 256 MHz overclock. It works a treat. Did a simple series of digitalWrites in a loop to track the speed improvement vs the clock speed increase
Rough numbers for a digitalWrite HIGH/LOW cycle
180 MHz ~ 167 ns
192 MHz ~ 155 ns
216 MHz ~ 138 ns
240 MHz ~ 124 ns
256 MHz ~ 117 ns
Temperature is definitely rising as expected, but using an infrared thermometer isn't spotting anything unusual.
The new clock speed will certainly be useful.
Thanks for all the effort in getting this out to us.
