Part of my testing of wiringPi v2. was to make sure that some of the existing libraries code would work with GPIO expanders – and the Adafruit RGB LED Plate was an ideal candidate.
So I ordered one, took a few moments to solder it together and plugged it in – and 5 minutes later I had my LCD test program working without any real issues.
So if you want to drive one of these from C/C++ or anything else that uses wiringPi, then be assured that it’ll just work!

Adafruit RGB Negative 16×2 LCD+Keypad Kit for Raspberry Pi – This new Adafruit Pi Plate makes it easy to use an RGB 16×2 Character LCD. We really like the RGB Character LCDs we stock in the shop. (For RGB we have RGB negative and RGB positive.) Unfortunately, these LCDs do require quite a few digital pins, 6 to control the LCD and then another 3 to control the RGB backlight for a total of 9 pins. That’s nearly all the GPIO available on a Pi! (read more)
