3.4 USER-LEDs & optional LC-Display (X15)
Eight LEDs are supplied for user applications. In order to disconnect the LEDs from the
related microcontroller port (Port P11), the resistor network N1 can be removed.
Instead of the user-LEDs, an alphanumeric LC-Display (optional) can be connected to X15.
The potentiometer P1 can be used to adjust the contrast of the LC-Display. Pin 15 and 16 of
X15 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 39T/0.5W, Pin16: GND).
The contrast of an optional LC-Display connected to X15 can be adjusted by P1.
The following control signals are provided:
