- Rx buffers weren't fast enough, had to use DMA :D - Basic LCD remote capabilities are working, single node - Multi-node broadcast seems to have a bug still - DMA ring buffer allowed for significant processing simplification * There is an overrun risk, but the buffer is large and generally there isn't too much data being sent (just very quickly) - Split out LCD layer stack capability into itself and an "exact" version used for updating remote nodes
