How to use the Parallax / Scott Edwards serial LCD backpack

Using Arduino Displays
1

this works (tested) with other scott edwards electronics backpack serial LCD's. I purchased these years ago from parallax. had them laying around, now i can use them. also, to send functions ie clear screen etc, myserial.write(12); <-- clr screen for bpp-420. sorry forgot to include that in the code. i dont believe the delays are needed in some cases, you will have to experiment a bit.

/*code to control BPP-420 Scott Edwards Elec. LCD. */

#include <SoftwareSerial.h>

#define rxpin 10
#define txpin 11
#define inverted 1

void setup() {
 SoftwareSerial myserial(rxpin, txpin, inverted);

  digitalWrite(txpin, LOW);
  pinMode(txpin, OUTPUT);
  myserial.begin(9600);
  delay(200);
  myserial.print("helllo");
  delay(100);
  
  
  
}

void loop(){
}

BPP-420 s.e.e. LCD

Perhaps you should change the subject to something like "How to use the Parallax / Scott Edwards serial LCD backpack" or something like that.

myserial.print("helllo");

Did you purposely misspell this?
