Mech Keycaps with Grovepi+

Hi Guys!

I need help with my project! I am using Raspberry Pi 3 with grovepi+ and am trying to get RGD LED working on the Mech Keycaps. Does anyone have any idea on how to get the LED working? I have tried analogWrite and digitalWrite doesn’t work and the SeeedStudio wiki only provided for Grove Base Hat.
