Hi, I wan’t to know how to know the available pins after using the shield for dmx send only.
I don’t need to receive dmx, and I need several free pins.
i don’t see on the library (DmxMaster/DmxMaster.cpp at master · TinkerKit/DmxMaster · GitHub) if there is any way to change the default pins; pin 4 is not named.
I don’t know if its something related to timers or just because de pcb paths.
I can see the schematics here (https://www.openhacks.com/uploadsproductos/dmx_shield_rev4.pdf) but I don’t understand too much…
Ps: I have the analog pins unused, so I can setuo them as digital IO, but is not ideal because I need to resold some cable connector that I have done…
Any help is appreciated
