"clear" clearly not working (at least for me) but I have a fix

Hey, your clear function inits the zero[128] array but never defines it, which lead to artifacts on my display. Here is the primitive fix you could probably solve way better:

uint8_t zero[128];
for (uint8_t i = 0; i < 128; i++) {
zero[i] = 0;
}

Memset is more concise :)

uint8_t zero[128];
memset(&zero,0,128);

[Nate Zimmer]

even more concise

uint8_t zero[128] = {0};
