daddesioIs there any 5V DC pin on the Icestick or the iCE40hx-8k board, or will I need a second USB port? (I need to talk with a 5V chip.)19:35
*** digshadow has joined #yosys19:36
daddesioWell, actually, I want to do two things. I want to talk with a 5V nvRAM chip (so I need to be able to accept 5V logic levels), and also power a GameCube controller, which expects 5V DC input.19:40
daddesio(I guess I still need to do testing to see if the full 5V are required. I don't need rumble at the moment.)19:41
ZipCPUDigilent sells a voltage level shifter that you might find valuable.  It plugs into a PMod port.19:44
mjoldfieldI don't think either board has 5V on the headers, but it would be easy to solder a wire to the relevant USB bin on the iceStick. Less so on the hx-8k20:07
mjoldfieldI have a slightly oddball question: suppose I have a bunch of logic expressed as verilog. I feel I ought to be able to get yosys to represent it as a bunch of, say, 2-input NAND gates, but I don't know quite how to do it. Does anyone have any pointers ?20:20
