Initial commit for UARTConnect module * 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

# UART Buffer Size
# Number of bytes to reserve for each side of UARTConnect
# For true NKRO support must be at least: <# of Keys> x 3 + 5
UARTConnectBufSize => UARTConnectBufSize_define;
UARTConnectBufSize = 128; # MDErgo1 requires at least a 119 byte buffer

# UART Speed
# *NOTE* This must be changed on every device in the chain or else UARTConnect will not work
# The faster the speed, the lower the latency, but higher chance for an error
UARTConnectBaud => UARTConnectBaud_define;
UARTConnectBaudFine => UARTConnectBaudFine_define;
# Generally, leave BaudFine at zero unless trying to tune the link to an external UART
# You'll want to look at the specific chip datasheet for the exact equation
#
# Example of 115200 Baud using a 48 MHz clock (mk20dx128vlf5)
# 48 MHz / ( 16 * Baud ) = BDH/L
# Baud: 115200 -> 48 MHz / ( 16 * 115200 ) = 26.0416667
# Thus baud setting = 26
# NOTE: If finer baud adjustment is needed see UARTx_C4 -> BRFA in the datasheet
# Baud fine setting = 0x02
UARTConnectBaud = 26;
UARTConnectBaudFine = 0x02;
