you all know Tom Van Baak's PPSDIV project in that a PIC microcontroller
acts as an sychronous frequency divider and generates a bunch of output
frequencies from a single 10 MHz input with an 1 PPS among it.
I have translated this project into the AVR world of microcontrollers
you can download an AVR Studio project that will enable an AVR
controller to perform the same. Much to the smaller cycle time of the
AVR's the 100 kHz output is almost perfect in terms of duty cycle. The
code should run on any AVR that features an complete port A since that
one is osed for the output.
My PLOTTER utility has been updated and now features an ALL-TAU option
for stability computations.
My EZGPIB utility has some errors less than before...
