4.5 USER-LEDs & optional LC-Display
Eight LEDs are supplied for user applications. In order to disconnect the LEDs from the
related microcontroller port (Port 15, Pin 0-4 and Port 16, Pin 2-5), the resistor network RN1
can be removed.
Instead of the user-LEDs an alphanumeric LC-Display (optional) can be connected.
The potentiometer RP1 can be used to adjust the contrast of the LC-Display. Pin 15 and 16
of J1 are normally not mounted. If the used LC-Display has pins for LED backlight at this
position, they can be connected here (Pin15: Vcc via 39Ω/0.5W, Pin16: GND).
The following control signals are provided:
