Pimoroni Display Pack modify RGB pins

Support
1

Greetings,
The Pimoroni Display Pack’s RGB uses GP6,GP7,GP8; GP8 is UART1.TX.
An expansion board I am using has 4-pin grove connectors but only has a header for UART1 on GP 8:GP9 – not GP4:GP5.

Can I cut the RGB traces and reroute them to other pins (I may only need to reroute GP8); if so is there something in the code beyond the line declaring the RGB pins e.g. rgbled_pim543 = RGBLED(6, 7, new_pin)?

I do believe all you need to do is edit the led = RGBLED(6, 7, 8) and change the (6, 7, 8) to the pins you want to switch too.

Thanks for response. Since there is not a smart RGB controller IC how is the 0…255 of each discrete LED color achieved–is the Pimoroni library PWM’g the 3 pins? If so then I’d have to find what pins on PicoW have PWM.

I hadn’t thought of that? I just remembered having to edit that line in my code for the new Display Pack 2.8, it uses (26, 27 and 28) instead of (6, 7 and 8)
