Extra GPIO Pins with the Adapter Board #666

Closed puffycholo closed 6 years ago

Good day. A noob question. Will i be able to use other GPIO Pins if I use the adapter board provided?

My project needs to daisy chain 6 panels and at the same time a GSM module connected to the Raspberry pi.

hzeller commented 6 years ago

If you use all three chains, there will be no GPIO left except the UART.

puffycholo commented 6 years ago

im only using 2 chains. where will i connect the gpio ports unused? i will be using this drive board

Yes, if you only use two chains, you can use the remaining GPIOs.

You find the available GPOSs by checking out the p2_XX values in https://github.com/hzeller/rpi-rgb-led-matrix/blob/master/lib/hardware-mapping.c

I will be using 64x32 panels. Do i need to tweak the adapters just like the 64x64 board config?

hzeller commented 6 years ago

No, 64x32 is essentially just a long 32. So no tweaking needed.
