I would like to make a CAN system using S32K144EVB. I would like to refer to the examples in S32DS, but there were three examples of CAN. The three were [sbc_uja1169_s32k144], [flexcan_encrypted_s32k144] and [FlexCAN_s32k144], and I don't know what the differences are in function. So, I would appreciate it if you would let me know this difference.
In addition, there are a few more questions I know that the example [sbc_uja1169_s32k144] is an example of switching the operating mode of the uja1169 CAN transceiver through the SPI. However, no code was found to send and receive CAN frame. How can I send and receive CAN frame using uja1169 in this example?
