3.1 Hardware Connection

LIN transceiver is needed to cooperate with MCU, as the LIN transceiver can transform UART signal to LIN signal.

Here we take LP-MSPM0G3057 and TLIN2029EVM for example. The hardware connection is shown as Figure 3-1. The two of the connections form a communication unit, and can be connected to another unit like MCU with transceiver, LIN Analysis to PC.

  1. Connect MSPM0G3507 UART pin to TLIN2029.
  2. Connect MSPM0G3507 Power pin(3.3V and GND) to TLIN2029.
  3. Connect MSPM0G3507 PB15 which served as enable pin to TLIN2029 ENABLE pin.
  4. Use external 12V power supply to TLIN VBAT pin. If the other connected communication unit like LIN Analysis has already connect 12V, then this step can be ignored.
  5. Connect VBAT,LIN and GND pin in TLIN2029 to responder or commander hardware.
  6. Power supply MCU.
