I’m using a Arduino Uno with a Serial LCD and 6 Analog inputs. 4 of the analog inputs work and the LCD works fine. I took out all the LCD items in the sketch and all 6 of the Analog inputs work. A4 and A5 stop when the LCD is activated. ??
Does the LCD use I2C? Those originate from A4, A5.
Yes it uses SDA and SCL
Does anyone have schematics and sketches for TLC2543CN Analog to digital converter?
