NORVI ARITA MEGA INDUSTRIAL APPLICATIONS #
Programming #
NORVI-ARITA-MEGA-M8 has a mini USB Port for serial connection with the SoC for programming. Any Arduino-supported programming IDE can be used to program the controller. Follow this Guide to programming NORVI Arduino-Based Controllers with Arduino IDE.
SoC: ATmega2560-16AU
Programming Port: USB UART
Digital Inputs #
Wiring Digital Inputs #
The digital inputs of NORVI-ARITA-MEGA-M8 can be configured as both a Sink and Source connection. The inverse of the Digital Input polar should be supplied to the common terminal.
Programming Digital Inputs #
Reading the relevant GPIO of ATMEGA gives the value of the Digital Input. When the inputs are in the OFF state the GPIO goes HIGH, and when the input is in the ON stage GPIO goes LOW. Refer to the GPIO allocation table in the Datasheet for the digital input GPIO.
