This looks like a nice little set of code to get another way of using the board without being tied into the huidu infastructure. However, I'm wondering, what benefits does this new firmware offer? What does it actually let me do? Does it basically just provide a framework to write my own code to take advantage of the ram and cpu leftover after running the hub75 updates?
It depends entirely on your use case and how much code you're willing to write. This code just gives you an example of how to flash basic custom firmware. It's not a product/useful in its own right
