2 32x64 LED matrices connected via GPIO - Raspberry Pi Forums
hello there,
work project (i work web development agency) we've decided experiments raspberry pi2. 1 of these experiments i've gotten green light little project involving 64x64 led matrices can found here:
http://www.led-card.com/product_info.ph ... cts_id=243
unfortunately maximum of 32 x 64, hope set 2 of these running in unison raspberry pi, controlling them gpio pins.
i'm @ bit of loss begin, i've found tutorials show how hook 2 32x32 matrices together, , there libraries out there handle io, example: https://github.com/hzeller/rpi-rgb-led-matrix, seem go size.
believe type of matrix can daisy chained together, i've read lot of stuff having use level shifters (which admittedly don't understand).
question is: have ever done similar? how best wire these? out of mind?
many thanks!

talk supplier. if don't know how it, either can't done, or shouldn't buying them.
