Automotive Communication: CAN Protocol

Describe the CAN protocol's architecture, including message frames, arbitration, and error handling.

Connect and configure a CAN transceiver (e.g., TJA1050) with the STM32.

Calculate and configure CAN bit timing registers for a specific bus speed.

Implement a function to transmit a standard CAN message.

Configure CAN acceptance filters to receive specific message IDs.

Set up a CAN receive interrupt (FIFO pending) to process incoming messages.

Parse a received CAN message to extract its ID and data payload.

Build a two-node CAN bus demo (if a second device is available) or use a CAN-to-USB analyzer to send and receive messages.
