- Works for all nodes in chain
- Synchronized to 30 ms update rate (required for ISSI chip)
  * Interconnect cannot handle full update speed from Scan module
  * Though it should be able to handle quite a bit more than 30 ms updates

- 6 modes
  * Single led: decrease, increase, set
  * All leds: decrease, increase, set
- Currently update speed limited to once every 30 ms
  * Likely an I2C driver or ISSI limitation preventing even faster updates

- Adds override functionality in main module

- Changing header file ifndef define to pragma once's
- Removed duplicate output_com.h's

- Basic screen initialization and clear is working
- Currently SPI is set to a low speed for easy logic analyzer debugging

- Not ready for advanced support yet
- Basic register and page writing support complete
