Hi KeSh_1984591,
Yes, you should be able to do this using PDL. But this will involve you to disable and re-enable the SPI hardware.
Define two different configuration structures. One that has CPHA = 0 & CPOL = 0 and other that has CPHA 1 & CPOL 1. Specific change would between the two structure would be as follows:
cy_stc_scb_spi_config_t configA;
cy_stc_scb_spi_config_t configB;
/* Other configurations are not shown here and must be done by you */
configA.sclkMode = CY_SCB_SPI_CPHA0_CPOL0;
configB.sclkMode = CY_SCB_SPI_CPHA1_CPOL1;
if(slaveSelect1)
{
while(Cy_SCB_SPI_IsBusBusy()!=0); //Ensure that busy is idle before you disable the SCB block
Cy_SCB_SPI_Disable(); //Disable the block
Cy_SCB_SPI_DeInit(); // SCB block must be disabled before calling this funciton
Cy_SCB_SPI_Init(SPI_HW, &configA, &context); //Init Config A.
Cy_SCB_SPI_SetActiveSlaveSelect(CY_SCB_SPI_SLAVE_SELECT0); //Set the active slave select0
Cy_SCB_SPI_Enable(); //Enable block only after all configurations are done
/* Start Transfer */
}
if(slaveSelect1)
{
while(Cy_SCB_SPI_IsBusBusy()!=0); //Ensure that bus is idle before you disable the SCB block
Cy_SCB_SPI_Disable(); //Disable the block
Cy_SCB_SPI_DeInit(); // SCB block must be disabled before calling this function
Cy_SCB_SPI_Init(SPI_HW, &configB, &context); //Init config B
Cy_SCB_SPI_SetActiveSlaveSelect(CY_SCB_SPI_SLAVE_SELECT1); //Set the active slave select1
Cy_SCB_SPI_Enable(); //Enable block only after all configurations are done
/* Start Transfer */
}
Hope this helps!
