Sample application for LIN08EY16 LINKits Slave Driver
Use the RCS command log to display revision history
information.
Slave supplies a 2-byte response with a selectable ID.
The data in the lower nibble of the first byte is the
hexadecimal number displayed on the 4 LEDs. This number
can be incremented using the button on port A, bit 4.
The default ID is $29 with $2A, $2B & $28 selectable
using an ID comfiguration mode. This mode is entered by
holding the button down for 3 seconds. After this the
LEDs flash and display the ID (0:29, 1:2A, 2:2B, 3:28).
Pressing the button in this mode increments the ID.
After three seconds of no activity on the button, the
mode returns to normal.
