Introduction

This example is a application which demonstrates the LIN message communication to external PC via PLIN-USB (from PEAK Systems -> IPEH-004052) Instance LIN1 is set as a Commander in Transmit Mode.

The LIN1 instance initiates the transmission by sending LINID followed by message. The size of the message is also increased with increasing id.

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 freertos
	r5fss0-0 nortos
Toolchain	ti-arm-clang
Boards	am263x-cc
Example folder	examples/drivers/lin/lin_external

Note

This Example is only functional on am263x-cc E2 board. This is not supported on am263x-cc E1 or am263x-lp. For support on these boards, please reach out to your TI representative. This example is only functional on Windows setup due to limited availibility of PLIN-View Pro.

Steps to Run the Example

• Board Configuration, change the SW9 to ON mode, and change the SW10 to 1-2.
  

  LIN SW9 set to ON

LIN SW10 connected in 1-2

• Hardware Conectivity, connect the PLIN-USB module to PC from USB and Serial Port to be connected as mentioned in the image below.

• Software Setup, Download and Install the PLIN-View Pro from https://www.peak-system.com/PLIN-USB.485.0.html?&L=1
• Click on LIN in the menu bar and connect to PLIN-USB. Make sure the LINMode for PLIN is Responder with Baud Rate of 19200.

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run

Overridding the default configurations

• To override the default configurations or initializations, uncheck the box of Default Configuration and rebuild the example. The same example will work without any other changes.
