LPC11C24 CAN driver Communication implementation method

funa — Thu, 20 Sep 2018 02:46:18 GMT

I'm new for CAN and LPC11C24. How to send and receive information through CAN on-chip driver? Do the specific contents of the functions in the following two structures need to be written by myself? Such as init_can()\can_transmit() and so on.

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////typedef struct CCAN_CALLBACKS {
   void (*CAN_rx)(uint8_t msg_obj_num);
   void (*CAN_tx)(uint8_t msg_obj_num);
   void (*CAN_error)(uint32_t error_info);
   uint32_t (*CANOPEN_sdo_read)(uint16_t index, uint8_t subindex);
   uint32_t (*CANOPEN_sdo_write)(uint16_t index, uint8_t subindex, uint8_t *dat_ptr);
   uint32_t (*CANOPEN_sdo_seg_read)(uint16_t index, uint8_t subindex, uint8_t openclose, uint8_t *length,
                                   uint8_t *data, uint8_t *last);
   uint32_t (*CANOPEN_sdo_seg_write)(uint16_t index, uint8_t subindex, uint8_t openclose, uint8_t length,
                                      uint8_t *data, uint8_t *fast_resp);
   uint8_t (*CANOPEN_sdo_req)(uint8_t length_req, uint8_t *req_ptr, uint8_t *length_resp, uint8_t *resp_ptr);
} CCAN_CALLBACKS_T;

typedef struct CCAN_API {
   void (*init_can)(uint32_t *can_cfg, uint8_t isr_ena);
   void (*isr)(void);
   void (*config_rxmsgobj)(CCAN_MSG_OBJ_T *msg_obj);
   uint8_t (*can_receive)(CCAN_MSG_OBJ_T *msg_obj);
   void (*can_transmit)(CCAN_MSG_OBJ_T *msg_obj);
   void (*config_canopen)(CCAN_CANOPENCFG_T *canopen_cfg);
   void (*canopen_handler)(void);
   void (*config_calb)(CCAN_CALLBACKS_T *callback_cfg);
} CCAN_API_T;
