I've been using a Seeed Grove I2C RGB LCD display - the monochrome red/black model.
I've got it working OK with the recommended Grove_RGB_LCD_Backlight library using wire.h and rgb_lcd.h. I was hoping to be able to turn off the backlight to put the device into a lower power mode but I can't find a way to do it. I tried likely looking commands like noDisplay, setRGB and blink, but nothing seems to affect the backlight.
Is it possible, or have I picked the wrong display?
Thanks guys. I did read as much stuff as I could find but was misled by the fact that the RGB version does allow backlight manipulation. But as you say the data sheet is clear.
