h1. Eval

* Big LEDs to test outputs / Backlight-PWM
* Amplified Buzzer to test buzzer output directly on MCU
* PWM output to test buzzers; 3V; normal and amplified
* Test for CANBus-cables;
** MCU with 4 inputs
** 4 outputs to control which line to be tested to detect shortcuts
** 4 outputs for LEDs to indicate errornous wire
** How detect shortcuts
** Button to reset
* Durchgangsprüfer ( buzzer-out / Buzzer-in )
** Do i really need this? Dont want to setup an multimeter
** Does not cost much
** The signal is already there. It might be usefull to inspect the board
