Recently I bought a 16x2 white-over-black LCD from SparkFun with the SparkFun Serial Backpack… I got it to say "†¥©¨∫˙ˆø “Hello World!” and plenty of gibberish…
It refuses to say anything anymore… not even gibberish…
I got this from Playground (RX connected to Pin2):
#include <SoftwareSerial.h>
#define txPin 2
SoftwareSerial LCD = SoftwareSerial(0, txPin);
// since the LCD does not send data back to the Arduino, we should only define the txPin
void setup()
{
pinMode(txPin, OUTPUT);
LCD.begin(9600);
}
void loop()
{
LCD.print("Hello world!");
}
this is what made it do stuff… not it’s pretty much a blank blinking cursor…
any ideas? The backpack is supposed to be “easy” to use… but there us very little sample code references for it out there… the ones that are worth anything are not for the serial backpack.
what do I do?
