I am inputting signals to the SPI module on my evm although I am not sure if the signals are reaching the data receive register correctly. My code initialises the SPI etc.. Slave = open(BSP_DEVICE_NAME_SPI_1, 0, &SpiParams); and then goes into this loop: for(;;){ ioctl(Led, LED_ON, LED_GREEN); read(Slave, (UWord16 *)(&Data),sizeofUWord16)); ioctl(Led, LED_OFF, LED_GREEN); close(Led); } Incidentally the green LED lights and doesn't turn off, so i know the code stays in the read function and should be reading the SPI register associated with the open SPI device "Slave" into the buffer "UWord16 Data" How can i look at "Data" so that i know this register is changing with the input signal. Also, have i got my spi signals connected to the correct pins? I'm using SPI1 on DSP56F827EVM, I have SCLK connected to pin 19, MOSI connected to pin 23, /SS connected to pin 29. (I do not have MISO connected) Thanks Calum
