3 Configuring the Koala EVM Hardware
The Koala EVM hardware is configured by setting on board jumpers.
3.1 CAN Bus Termination
For high speed or long distance transmission, it is recommended to enable the CAN termination resistor. This is
done by shorting J2 pins.

– enables CAN termination resistor
3.2 USART2 / FSMC (LCD) Selection
A UART peripheral and the LCD controller share a data line on the Koala EVM, and the required function must be
selected accordingly.
If any of the WMI modules require access to USART2, then CN21 pins 1-2 must be connected.

To enable LCD functionality, CN21 pins 2-3 must be connected.

4 ST-LINK Configuration: Programming / Debugging the
Koala EVM
The embedded ST-LINK can be used to program the on board microcontroller and debug applications. Configure
the jumpers as shown below to enable ST-LINK program/debug.
