I need 4 RGB LEDs for my next project. In theory you should be able to charlieplex these with 4 pins on an MCU. I just realized though that maybe it won't work since the LEDs have common cathode or anode pins.
Will it still work or do I need more pins? I can order both common cathode and common anode LEDs if it helps (maybe 50/50 or something).
