- 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

- Still some issues
- Will require some changes to MatrixARM and PartialMap
  * Currently state information is passed around too frequently
  * Needs to be reduced to state changes only

- Fixed cli reflash mode set
- Cleaned up debugging code
- 4 500 000 baud seems to be reliable
- Fixed master selection (assumes slave node unless USB enumerates)

* Keyboard interconnect using two uarts
* Supports daisy chain addressing using a master/slave direction communication scheme

- Still needs more testing
- Functions have been tested alone to be generally working
