This LCD is a small I2C display module that has a 16x2 character display. The text appears white on blue, with a dimmable backlight. Information and libraries for this chipset were a little hard to find, so I have listed some resources here for reference.
The officially provided library appears to be some monochromatic re-implementation of Seeed Studio’s Grove LCD RGB Backlight that can be found at: https://github.com/Seeed-Studio/Grove_LCD_RGB_Backlight
I could not find a datasheet for this chipset, however I came across the information sheet which had some broken links. (http://www.west-l.com/uploads/tdpdf/104030001_eng_tds.pdf)
- This display uses a AiP31068L chipset, that is not compatible with the more common HD44780 chipset.
- There are actually two I2C devices in the module, one for the backlight, and
one for the character display. Their addresses are:
#define LCD_ADDRESS (0x7c>>1) // character 0x3e #define RGB_ADDRESS (0xc0>>1) // backlight 0x60
- Note for the Arduino Uno, the I2C pins are A4 (SDA) and A5 (SCL).
