11 LIN Master

The PGA450-Q1 GUI communicates with the PGA450-Q1 using LIN. The USB Communication board

UART is the LIN master, and the PGA450-Q1 is the LIN slave. The GUI can be used to configure the LIN

frames that are transmitted to the PGA450-Q1.

Figure 9. LIN Master on GUI

In order to transmit data to PGA450-Q1 using a LIN frame, the user must do the following:

1. Enter the Frame PID in Edit Box corresponding to “Tx Frame PID”. The PID must be entered in hex.

Note that valid PID ranges from 0x00 to 0x3F. The GUI software calculates the parity bits using the

LIN 2.1 method before the PID is transmitted to the slave.

2. Enter 0–8 bytes of data in the “Data to be Txed” box. Each data byte must be entered in Hex.

3. Select the CLASSIC or ENHANCED checksum, which must match the LIN checksum setting in the

PGA450-Q1 ESFR LIN_CFG register.

4. Click on the TRANSMIT button

In order to receive data from PGA450-Q1 using a LIN frame, the user must do the following:
