Describe the solution you'd like
Add a simple "compression" to framebuffer uploads. The unused
upper 8 bits of an RGB value can be used as a repeat count. It tells how
often the same color shall be used on the pixels that follow.
This significantly reduces frame buffer traffic to the websockt, expecially for 64x64 layouts.
Example:
To upload an empty black 32x8 frame buffer, only a
single 0xFF000000 data value will be send.
Describe alternatives you've considered
Use zlib or other compressions. But these0 likely increase flash footprint causing issues with 4 MB modules.
