Dear experts!
Maybe one of you has already an LCD-initialization code example for the LCD 1x9 - module. Maybe with a good description of the code. For example how to get maximum contrast? And explaining all the commands? Would be happy to have (without mapping or exchanging of command names etc.).

I am not sure if you can change the contrast of MOD-LCD-1x9 via a command. I believe PCF8576D's contrast is only related to input voltage. Hence if you have poor contrast, probably the board is not sufficiently powered.
We have provided few libraries and demo code at the product page.
