flex CAN pins configuration

[chris_010]

env: S32DS3.5 + RTD4.0

I open Built-in examples--“FlexCAN_Ip_Example_S32K344”，I find  there is no configuration regarding the pins.Is it right?Does it uses any default configuration?How can I find them.

Hi @chris_010,

The FlexCAN_Ip_Example configures the FlexCAN instance as loopback, send frames through ISR and receive as polling, as explained in the description.txt file:

Meaning no pins are configured for it. You can change FlexCAN to "Normal/user mode" and configure PTA6/7 for CAN_RX/TX. You can refer to community examples:

• Example S32K344 FlexCAN_Ip TX/RX/EnhanceRXFIFO DMA test S32DS3.5 RTD400 - NXP Community
• [RTD600 MCAL & IP] S32K3X4EVB-T172 FlexCAN Example Interrupt/Polling - NXP Community
• Example S32K312 CAN Transmit & Receive Using MB Interrupt DS3.5 RTD300 - NXP Community

Best regards,
Julián
