What is max sample rate of the FPGA?

Bryscus · #1 26-01-2009, 10:42

Hello all,

I've had no luck in trying to find some information on the FPGA sampling rates. I've tried to dive into the WPILIB source code that was provided, but I can't find any definite answers. I'm sure the FPGA has a sample rate much higher than anyone will realistically need, but I don't know. Anyone have some answers? Thanks.

You will need to be more specific with your question. What aspect of the FPGA are you concerned with?

Analog Inputs are sampled at 500kS/s spread over 8 channels. Digital Inputs are sampled a little quicker than every 7us (I can't remember the exact number) in general, but specific ports are slower.

Per this Q&A the DIOs are sampled at 153kHz.

Cool, thanks.
