    can't write to P-port databus from FX3

      Dear Sirs,


      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?


      Also, I tried RSKV's example GPIF_EXAMPLE2.zip, but when I program FX3 device, the device is not recognized, and usbview.exe doesn't see any device.
