I have just gotten my Matrix Creator and I would like to expose an Rpi GPIO via the expansion gpio on the matrix creator. I am new to FPGA programming and I’ve tried to follow the guide here:
But it seems that this is for the Matrix Voice that already has some GPIO pins defined for this purpose. Following the datasheet for the matrix creator I would like to use GPIO26 as it is unused and wire it to the expansion GPIO10. Unfortunately i’m not sure where to begin as I can’t find GPIO26 defined in the creator.ucf file. I assume that i would have to define my own pins?
Are there any resources or tutorials i could follow as i do not want to risk messing up the verilog code for my Matrix Creator. Thank you!
