Hello,
I am trying to interface my MSP430G2553 launchpad with an LCD (http://www.winstar.com.tw/UserFiles/ProductImages/12523136510757108108.jpg) but my characters look weird. I am using http://www.fibidi.com/arduino-lcd-16x2-characters/ with one potentiometer , with changing ports like this:
#include <LiquidCrystal.h>
// initialize the library with the numbers of the interface pins
//LiquidCrystal lcd(8,9,4,5,6,7);
LiquidCrystal lcd(P2_4,P2_5,P2_0,P2_1,P2_2,P2_3);
void setup() {
lcd.begin(16,2);
lcd.setCursor(0,0);
lcd.print("Hello World!");
}
void loop() {
}
But my characters looks like this with 3.6V to LCD:
And if I use 5V from TP3 TP1 from Launchpad USB thing with highest brightness:
I tried:
1. using other ports (1.0 to 1.7)
2. changing potentiometer
3. changing and checking breadboard
4. checking voltages 3.6v -> 3.5 and 5V -> 5.09V
5. not using backlight
6. wiring empty LCD pins to ground
7. removing lcd.setCursor(0,0); line
8. trying MSP430G2452
But still same. I alson can't use right half of the screen.
It should work but, is something wrong with LCD (that was my first soldering attempt I may overheat something but I checked for short circuits and there isn't any) or my chosen ports.
Any ideas?
Thank you.
