LCD-plug not working...?

Postby jakkes » Sun Jul 10, 2011 7:37 pm

After a few months of doing noting with my jeenode's i am starting again..

I tried displaying "Hello World" on a LCD plug
I use this sketch:
#include <PortsLCD.h>
#include <RF12.h> // needed to avoid a linker error :(

PortI2C myI2C (1);
LiquidCrystalI2C lcd (myI2C);

void setup() {
// set up the LCD's number of rows and columns:
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print("Hello World");
}

void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
lcd.print(millis()/1000);
}

I only see a blue screen...., no text on the lcd.
Tried turning the pot on the back: no response on/off the screen...

Found it:

It seemed that there had to be a solder "bridge" on de logic part...
