I am trying to initiate an SPI transmission over these ports:
SCLK: PTC15
MISO: PTE16
MOSI: PTC1
CS: PTC14
but the CS isn't working at all. But if I change CS to PCS3 then it works, which is not cool because I already have my PCB pinout to PTC14.
Another Problem is that I cant seem to see any data on MISO: PTE16. Should I be considering another art of port initialization when I have 2 Ports?
I init them like this:
PCC->PCCn[PCC_PORTE_INDEX ]|=PCC_PCCn_CGC_MASK; /* Enable clock for PORTE */
PCC->PCCn[PCC_PORTC_INDEX ]|=PCC_PCCn_CGC_MASK; /* Enable clock for PORTC */
Hi,
if a PTC14 pin is configured to select LPSPI2 PCS0 function and LPSPI2 TCR is selecting PCS0, then you should see signal on it.
If PTE16 is used as SIN then PTE port clock have to be enabled too.
