4.2 CAN Examples

All TM4C micrcontrollers come with at least one Controller Area Network (CAN) module and this application report provides two examples that should be used in conjunction with one another to demonstrate a robust CAN application using multiple message objects. To run these examples on either TM4C LaunchPad™ Evaluation Kit, it is required to connect CAN transceivers to the BoosterPack™ headers for the associated CAN signals.

It is important that when running the CAN examples on EK-TM4C1294XL LaunchPad Evaluation Kit, the JP4 and JP5 jumpers are changed to their vertical positions. JP4 and JP5 are used to configure CAN signals to the BoosterPack 2 interface. In the default horizontal configuration, CAN is not present on the BoosterPack. UART2 goes to the BoosterPack and UART0 is connected to the virtual COM port of the ICDI. In the vertical CAN-enabled configuration, UART2 goes to the ICDI virtual serial port and CAN signals are available on the BoosterPack. For more details, see the Tiva™ C Series TM4C1294 Connected LaunchPad Evaluation Kit - EK-TM4C1294XL.
