I am using a USB Pmod to transmit data from a QT app on my computer to the PL of an FPGA dev board ( ZCU104 ) half duplex PC->FPGA. It all works great, but I find the reference manual really confusing. It took me a while to figure out that the data from the PC is at pin 3 of the Pmod connector, not pin 2, even after years of using com ports because of the language in the manual. A simple diagram with arrows pointing in the data flow direction would be really helpful for us old idiots.
