Re: [Fx2lib-devel] Generating a clock with the GPIF

[Eric W. <er...@wi...>]

There is no good way to make a programmable high frequency clock on the 
FX2.  You can make a low frequency clock using an internal timer driving 
a GPIO pin.  You will be limited to a resolution of 4 or 12 FX2 CPU 
clock cycle periods.  Any thing high frequency will have the CPU always 
servicing the timer interrupt.  I would not do this for any thing beyond 
audio frequencies.  Why not just use a small clock oscillator.  The size 
would likely be a fraction of the imager size.
