DM103 LIN Viewer¶
This is a general µC + LCD board, which has been configured as LIN bus master. The OLED display shows the last eight received LIN bus packets (2..8 bytes data).
Warning
This has been superseded by the LIN Monitor module, which has a more useful activity display.
Usage¶
- There's not much to do, just plug it into an expansion base.
