Correct library for DFR0556 2x16 char backlit LCD display?

Hi All,

I'm struggling to find the correct library to drive my new DFR0556 2 line backlit display.

The product's page links me to an RGB library, but this version of the display only has a single LED backlight.

The library makes reference to backlight control commands, but they don't appear to be implemented (or have been partially removed in this up-issue adding RGB support?)

[DFR Wiki page](https://wiki.dfrobot.com/Gravity__I2C_LCD1602_Arduino_LCD_Display_Module_SKU__DFR0555%5CDF0556%5CDFR0557)
Linked GitHub repo - for [Grove - LCD RGB Backlight](https://github.com/DFRobotdl/DFRobot_LCD)

I can write to and clear the display, but I can't turn the backlight off, or change the contrast.

Can anyone point me to the correct library for this beastie??

Thanks,


Greig.
