3.5 mcan_multi_message_tx_tcan114x

This example demonstrates the MCAN external transmit function to send multiple messages using the BOOSTXL-TCAN1145 BoosterPack™. External communication is done between two CAN nodes. The receiving node can be another MCU or a CAN bus analysis tool capable of receiving or acknowledging the transmitted frames. Connect both CAN nodes through a CAN transceiver. This example can be used with the mcan_multi_message_rx_tcan114x example project. A nominal bit rate of 250kbps and data bit rate of 2Mbps are used.

The software first initiailzes the TCAN114x module through SPI. Meanwhile, TX messages are stored in the CAN message RAM as buffer mode. Then, use a software call add request for the transmission API to transmit messages in the desired TX buffer.
