Title: continuous clock?
Post by: ost on February 04, 2019, 11:56:18 AM
Is there any way to set FT2232H to output continous (stable) clock on SCK pin? I would like it to execute MPSSE commands on top of this, synchronized to the SCK edge like normal, shifting in and out on active CS only.

Unfortunately it would not be possible to produce a continuous Clock signal using MPSSE commands. At some point the MPSSE commands would be split across a USB packet, the timing of USB packets is not deterministic and this will result in a pause with your Clock signal. The MPSSE functionality was designed as a clocking engine for data and not to run continuously.
