HookupIn the pic at right (click to enlarge), a BPI-216L is connected to an Arduino Uno via a BSW-CBL wiring harness (a worthwhile option when you're buying the display). Connections are
- Red: Arduino 5V to BPI +5
- Black: Arduino GND to BPI GND
- White: Arduino 3 to BPI SER
#define txPin 3to the desired pin number.
