can't write to P-port databus from FX3
I connected GPIF databus to LEDs for viewing data, and I wrote firmware to pass data on P-port (GPIFII). But there are not data. Use of CyU3PGpifWriteDataWords() API, sockets is unsuccessful. I just want drive data on databus now, but It doesn't work. I use Master Asynch mode without input signal. What is wrong?
