twai_hal_parse_frame() function

Pointer to frame structure

Pointer to empty message structure

Copy a frame into the TX buffer and transmit This function copies a formatted TX frame into the TX buffer, and the transmit by setting the correct transmit command (e.g. normal, single shot, self RX) in the command register.

Parse formatted TWAI frame (RX Buffer Layout) into its constituent contents

Format a TWAI Frame This function takes a TWAI message structure (containing ID, DLC, data, and flags) and formats it to match the layout of the TX frame buffer.

Copy a frame from the RX buffer and release This function copies a frame from the RX buffer, then release the buffer (so that it loads the next frame in the RX FIFO). False is returned under the following conditions: - On the ESP32S2, false is returned if the RX buffer points to an overrun frame - On the ESP32, false is returned if the RX buffer points to the first overrun frame in the RX FIFO

Copy a formatted TWAI frame into TX buffer for transmission

Copy a received frame from the RX buffer for parsing

Format contents of a TWAI frame into layout of TX Buffer This function encodes a message into a frame structure. The frame structure has an identical layout to the TX buffer, allowing the frame structure to be directly copied into TX buffer.
