How to use FlexCAN1 to communicate with FreeMaster

ChenBowen · ‎08-15-2022

Dear Expert：

MPC5744P，now I need to use CAN1 to connect with FreeMaster，because the CAN0 is being used by app.

The Freemaster SDK only uses CAN0，is it possible to use CAN1 ？

You can configure FreeMASTER Driver to use CAN1 by updating its corresponding base address in freemaster_cfg.h:

/*****************************************************************************
* Select communication interface (SCI/FlexCAN base address)
******************************************************************************/

#define FMSTR_SCI_BASE         0xFBE84000UL /* LINFlex0 base on MPC574xP */
#define FMSTR_CAN_BASE         0xFFEC0000UL /* FlexCAN0 base on MPC574xP */

Note: FreeMASTER Driver does not configure the CAN interface, the setup is expected to be done in your application code.
