Hi guys (& ladies).
I am running a sparkfun serial lcd board from an arduino mini. The problem im having is using the second example from:
http://www.arduino.cc/playground/Learning/SparkFunSerLCD
to run the lcd from pin2 not the arduino’s tx (pin 0), hence using SoftwareSerial.
When I try uploading the code to the Arduino Mini, I get the error:
serialLCD_example:30: error: ‘class SoftwareSerial’ has no member named ‘write’
I can change the code from LCD.Write to LCD.Print and it uploads fine however doesn’t display correctly.
This is frustrating the heck out of me as I was working with an lcd via serial about 6 months ago, with no probs.
Thanks in advance.
Here’s the code anyways:
#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
const int LCDdelay=10; // conservative, 2 actually works
// wbp: goto with row & column
void lcdPosition(int row, int col) {
LCD.write(0xFE); //command flag
LCD.write((col + row*64 + 128)); //position
delay(LCDdelay);
}
void clearLCD(){
LCD.write(0xFE); //command flag
LCD.write(0x01); //clear command.
delay(LCDdelay);
}
void backlightOn() { //turns on the backlight
LCD.write(0x7C); //command flag for backlight stuff
LCD.write(157); //light level.
delay(LCDdelay);
}
void backlightOff(){ //turns off the backlight
LCD.write(0x7C); //command flag for backlight stuff
LCD.write(128); //light level for off.
delay(LCDdelay);
}
void serCommand(){ //a general function to call the command flag for issuing all other commands
LCD.write(0xFE);
}
void setup()
{
pinMode(txPin, OUTPUT);
LCD.begin(9600);
clearLCD();
lcdPosition(0,0);
LCD.print(“Hello world!”);
}
void loop()
{
}
