Use Elixir over GPIO and Rpi to Drive LED Array?

Questions & Help Questions
1

I’m looking to drive a large LED array with Elixir – is this a good idea?
I’d like to just keep scaling the hardware to a get a larger and larger led matrix.

Thanks!

How large is ‘large’? What do you want to do with the LED array?

I think that as long as the Raspberry Pi can handle the larger LED matrices, the Elixir+Nerves software will be able to do so as well. However, what I do not know is how fast the update speeds to the matrix will be.

As many as I can add where I could keep the refresh rate of 100 Hz. Again the big questions is the refresh speed?
I’ve seen this repo using GPIO (all of them) to drive some larger panels.
