Hi,
I have a program that is triggered by the unit’s internal clock. Is there a way to trigger off of something external (but NOT the USB). Can I wire a signal to a pin and have it trigger off a rising edge? If so, how?
Thank you
Sure. You can provide an external clock to the FPGA.
I am a bit of a newbie, how can I do this/ where is it described?
Generally, this is described in the Spartan-6 documentation provided by Xilinx. You can download all such documentation on their website.
The XEM3001 User’s Manual has a guide at the back that shows which FPGA pins are attached to which locations on the PCB.
