Discussion - Hardware / SPI mode clock duty cycle
« on: November 27, 2017, 09:36:04 AM »
Hi
We face a rather strange status on the circuit using FT2232H. We need to use the SPI at 3 MBit/s. By probing the lines with scope, it turn out that the duty cycle of the clock is around 25% and in fact we are not getting the speed that we needed.
Any suggestion?
