Serial LCD 20x4 connection

#1 Post by bluetrainer »

I am trying to build the B58 transponder, and I am unable to display the text on the 2004 serial LCD (20x4).
I am using the Hardware Function (digital transponder) in Air Manager with the X-plane 11, to connect it; the display glows, but doesn´t show anything.

It won't, it is written for a 7219 8 digit 7 segment display.
You would need to rewrite the whole unit.
