i've downloaded the miniMAD_3_1_171123_16GB.img.zip but i can't extract (winRar - 7zip), it say "unexpected end of packet".
i've updated the miniMad from madmapper but it still suggest to update.
the problem is that my ledstrips (5050- 2812b), connected to a teensy, that is connected via USB to the computer (Route Artnet to USB Led Device), won't light up with the miniMad. any suggestion? thanks a lot
