UC3C CAN and LIN Loopbacks Application for uc3c_ek Documentation

Introduction

This is the documentation for CAN and LIN loopback demo application running on the UC3C_EK development kit.

• Step 1: The potentiometer value is read and displayed on the LCD screen.
• Step 2: The value of the potentiometer is sent through CAN network.
• Step 3: The content of the received message on CAN network is displayed on the LCD screen and corresponds to the screen observed in step 1.
• Step 4: The same message is also transmitted on LIN bus
• Step 5: The content of the message received on LIN network is displayed on the LCD screen and should correspond to the screen observed on step 1,3.
