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
