4.5USER-LEDs & optional LC-Display (J1)

Eight LEDs are supplied for user applications. In order to disconnect the LEDs from the related microcontroller port (Port P09), the resistor network RN1 can be removed.

Instead of the user-LEDs, an alphanumeric LC-Display (optional) can be connected to J1.

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 39S/0.5W, Pin16: GND).

The contrast of an optional LC-Display connected to J1 can be adjusted by RP1. The following control signals are provided:
