I started using a Nokia 5110 display for the first time a few days ago and I have some questions.
Is there a list of commands that are used with this display without using a library? Like LcdWrite or LcdString or LcdWrite(0, 0x0D); and so on. Sometimes I find myself knowing the steps when I try to do something but not knowing the commands.
I used this page and it was very useful. Arduino Playground - PCD8544
One problem I had is with inverting text. I don't know how to invert a single line of text. When I use LcdWrite(0, 0x0D); it inverts the entire display, not just the text I want to be inverted.
I used the Adafruit library and I managed to make things work just like I want them to work. Now I am trying to make them work without a library.
Another question I have is about text size. On the Adafruit library I can get 14 characters (6 pixels per character) on a column. With the playground example I can only get 12 (7 pixels per character). Is there a way to get 14 characters on the playground example?
Any help would be appreciated.
