I just received my Adafruit Blue&White 16x2 LCD+Keypad Kit for Raspberry Pi
. And while I was all ready to solder this kit together to plug into my RPi, I realized I wanted the optional Stacking Header for Raspberry Pi
which is currently out of stock.
So, in the interim I decided to use my cobbler and breadboard to light up the Blue&White LCD display alone using this
tutorial "Drive a 16x2 LCD with the Raspberry Pi". When I was all finished wiring everything up, I used the Adafruit_CharLCD.py source code to test my work. At first it didn't look as if it was working. However, after increasing the contrast, I could see the text. But, it is not displaying as white text on the blue lit background. Instead, it is displaying as dark blue text and is very hard to read. Is this normal, or is there something in the code I need to change to get white characters? or perhaps the wiring? I ask since the tutorial is for a regular LCD and I'm using the one that came with the kit.
Here is a photo
of the setup after wiring that show the dimly lit LCD
Can someone let me know if this is normal or if perhaps I need to adjust the code or wiring to get my white letters.
