My goal is to send data from the fpga to the pc using DSPI. This data, in this case RGB data, gets transformed into video using Unity. There are, however, several problems with sending data from the fpga to pc. Currently the pc is receiving data from the fpga as follows, From the pc side: Open the device (NexysVideo) using the function DmgrOpen(&hif, "NexysVideo") Enable DSPI transfer using the function DspiEnable(hif) Set the SPI mode using the function DspiSetSpiMode(hif, idMod, fShRight) Set the master (pc) clock frequency using the function DspiSetSp
I have my proMX7 board running a very simple code that I adapted from Robogaia.com. I use the code to access an LS7366 Quadrature Counter and Rotary Encoder. The proMX7 is also driving an LKM1638 (8 digits LED driver board). I use the LKM1638 as a display output to read the LS7366 count value. Both peripherals are driven via SPI communication and using DSPI virtual object library. I am using two distinct ports, one for each peripheral. JA is connected to the LKM1638 display and JE is connected to the LS7366 counter via pins 1 2 3 4, SS3 SDO3 SDI3 SCK3. The code is very simple. I send a Read re
