Version 1.0 of the Arduino software includes an update to the SoftwareSerial library, which (among other things) can output inverted-TTL serial that works with our BPI-, BPK-, and BPP- series devices. The example sketch is after the break.
Hookup
In 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
If you want to use a different Arduino pin for serial output, you can change the 3 in
#define txPin 3 to the desired pin number.
