Socket CAN driver (Zephyr)

Interface Functions

int csp_can_open_and_add_interface(const struct device *device, const char *ifname, uint16_t address, uint32_t bitrate, uint16_t filter_addr, uint16_t filter_mask, csp_iface_t **return_iface)
[source]

Open CAN and add CSP interface.

Parameters:

  • device – CAN device structure.

  • ifname – CSP interface name.

  • address – CSP address of the interface.

  • bitrate – CAN bitrate.

  • filter_addr – Destination address you want to set in the RX filter.

  • filter_mask – Bit mask you want to set in the RX filter.

  • return_iface – Added interface

Returns:

#CSP_ERR_NONE on success, otherwise an error code.

int csp_can_set_rx_filter(csp_iface_t *iface, uint16_t filter_addr, uint16_t filter_mask)
[source]

Set CAN RX filter based on destination address and bit mask.

Parameters:

  • iface – Interface to set the RX filter.

  • filter_addr – Destination address you want to set in the RX filter.

  • filter_mask – Bit mask you want to set in the RX filter.

Returns:

Filter ID, a negative value on failure.

int csp_can_stop(csp_iface_t *iface)
[source]

Stop the CAN and RX thread

Parameters:

  • iface – Interface to stop.

Returns:

#CSP_ERR_NONE on success, otherwise an error code.
