Hi. I have been made SPI slave activation but I have a problem.
I hope somebody helps me
Master : S32K144 (64pin)
Slave : S32K144 (64pin)
- In case Master's PCS polarity and Slave's PCS polarity are 'Active low', Slave does not transfer.
- Only in case both PCS polarity are 'Active high', Slave transfers correctly
- Master : PCS polarity is Active low
- Slave : PCS polarity is Active low
- PCS polarity is Active low(yellow) and Slave does not transfer(pink)
- PCB polarity is Active high(yellow) and Slave trasfers(pink)
void PORTB_ISR(void) // PCS is input to PTB0 and PORTB generates interrupt for falling edge
INT_SYS_InstallHandler(PORTB_IRQn, &PORTB_ISR, NULL);
