LED control (marlin firmware) with v4.5.2 board
I'm looking for a free pin on the 4.5.2 board to act as the data pin for a RGBW led strip.
Are there any free pins, like p9, p8 on the board which can be used? and how do they correspond to the ARM chip (This uses PCx PAx or PBx in the firmware)...
Anyone who can help me with this?
