Discussion - Software / SPI read delay in FT2232H with libMPSSE
« on: November 11, 2022, 12:11:50 PM »
Hi,

I have been using the ft2232H board with libmpsse module for SPI reading in windows/raspberry pi. In both cases, I read 3KB of data with 20Mhz frequency. It takes about 4ms seconds for every read. My problem is that when I read 20 minutes one or two times the read time goes above 100ms. Is it related to ftdi driver issue?

Regards,
Eisenheim
