4.1 GPIO Reconfiguration

The example programs run under the Driverlib frame work. They were tested with the following GPIO configuration for the CAN pins (see Table 4-1).

Table 4-1 GPIO Pin Mapping Used for the Examples
CAN FunctionGPIO
CANTXAGPIO71
CANRXAGPIO70
CANTXBGPIO72
CANRXBGPIO73

The C2000Ware examples, by default, have the following GPIO configuration for CAN operation:

#define DEVICE_GPIO_CFG_CANRXA      GPIO_30_CANRXA  // "pinConfig" for CANA RX
#define DEVICE_GPIO_CFG_CANTXA      GPIO_31_CANTXA  // "pinConfig" for CANA TX
#define DEVICE_GPIO_CFG_CANRXB      GPIO_10_CANRXB  // "pinConfig" for CANB RX
#define DEVICE_GPIO_CFG_CANTXB      GPIO_8_CANTXB   // "pinConfig" for CANB TX

This may have to be modified depending on which GPIO pins are used for CAN operation in your hardware. This is a very important step and, if applicable, must be done for every example project. Use the procedure discussed in Section 4.1.1 to change the GPIO configuration.
