LCD RGB Adafruit Library

Post by balcells »

Hello,

I would like to have more fine control of the LCD I purchased in an arduino shield kit.
Here's the product: http://http://www.adafruit.com/products/714
Here's the library: https://github.com/adafruit/Adafruit-RG ... CDShield.h

It would be ideal to make a custom character by choosing which of the pixels in an individual square were lit up, but all I'm really looking for at the moment is to display a solid block (Like the cursor using the function 'blink()', but not blinking...).

I noticed the function ' void createChar(uint8_t, uint8_t[]);'. What is this used for?

Also, I'm guessing that I will need to use some of the lower level functions of the library for the LCD Shield Kit. Can someone explain to me the 'command' function? Or point me to documentation which might enlighten the choice of the values for the "command" constants in Adafruit_RGBLCDShield.h

The CreateChar command is covered in this tutorial: http://learn.adafruit.com/character-lcd ... ar-command
General information on low level programming of HD44780 displays can be found here: http://www.adafruit.com/datasheets/HD44780.pdf
Constant definitions for most of these commands are defined in the header file for the library.
