Typedef Documentation

◆ can_reg_entry_t

typedef struct can_reg_entry can_reg_entry_t

registry entry

This structure is used through the stack to describe how to contact the upper layer and which CAN interface to use

◆ can_rx_data_t

typedef struct can_rx_data can_rx_data_t

Received data structure.

This structure is used when a layer sends received data to the upper layer
