LIN Configuration for MC9S12ZVL64 QFN-32

aly_sherif — Wed, 04 Dec 2019 16:07:33 GMT

i am trying to use the LIN Transceiver in the micro controller and i am also using pins 20 and 21 for SPI Communication.

Here is my current configuration:

- pin 20 is configured as MISO0 instead of RXD0.

- pin 21 is configured as MOSI0 instead of TXD0

The problem is:

i can't configure the SCI for LIN communication because the pins are already used in SPI communication as they use RXD0 and TXD0 ( the ones used for SPI communication) so when i add a new Asynchronous slave on processor expert for the LIN communication, i get errors as pins are already in use by the SPI.

Hello,

Have you considered to use channel SCI1 in the AsynchroSlave bean instead of SCI0?

I hope it helps.

Best Regards,

Diana
