Need help with SPI configuration - data is not getting transmitted Posted on April 07, 2017 at 20:38
Hello, I would like to know what is wrong with my current configuration of SPI module. I can see data in the TX FIFO, but its not getting transmitted.
I am using the
SPC570S40E1 microcontroller.
SPI Port Configuration
void Initialize_SPI_Port(void)
{
// Using DSPI 0
// DSPI0_CS -- PA[0] , Pin #2, PAD[0]
SIUL2.MSCR_IO[0].B.SSS = PAL_SPC5_SSS(1);
// DSPI0_SCK -- PA[3] , Pin #3, PAD[3]
SIUL2.MSCR_IO[3].B.SSS = PAL_SPC5_SSS(1);
// DSPI0_MISO -- PA[4], Pin #4, PAD[4]
SIUL2.MSCR_IO[4].B.IBE = 1;
SIUL2.MSCR_MUX[624-512].R = PAL_SPC5_SSS(1);
// DSPI0_MOSI -- PA[7], Pin #5, PAD[7]
SIUL2.MSCR_IO[7].B.SSS = PAL_SPC5_SSS(1);
}
