Whenever i read from the SPI's &ArchIO.Spi1.DataRxReg, the value read is always zero. How could i get the register to change? Is it directly connected to the MOSI pin when the DSP is configured as a slave. When i input the SPI master signals i can view the signals going into the DSP are correct. I have an SCLK, /SS and MOSI connected (but no MISO). However on stepping through my code it is evident that the &ArchIO.Spi1.DataRxReg always stays at zero but it should change with the data input to the MOSI pin. Using the dsp56f827 board MOSI = 23, SCLK = 19, /SS = 29 |
&ArchIO.Spi1.DataRxReg is always zero
