* Changed ATmega168 example for ATmega328 on Arduino Uno R3 with DFR0259 RS485 shield. Added ADC interface from BDK port and mapped to some AV objects. Removed MS/TP MAC address DIP switch GPIO and moved MS/TP configuration to AV objects. Added AV units property. Added some Uno R3 Digital Inputs and outputs mapped to some BV. Added AVR EEPROM from BDK port and mapped some non-volatile data including MAC address and max manager and baud rate, device ID and names and description and location.
