I've used a lot of s6 boards in the past, and I'm currently switching from the S6 to the A7 cmod (as I can't buy the S6 anymore). The S6 however had a faster and better interface to the USB chip than the A7 allowing communication via the EPP mode.
What is the fastest rate at which you can drive the UART_TXD_IN and UART_RXD_OUT pins? I was wanting to get at least 1Mbps off the board (preferably 12Mbps).
For 12MBaud can this be done with the Digilent Adept software interface or do I need to go to the D2xx drivers from FTDI?
