With Arduino IDE, the product program handles HMI requests through the built-in communication functions in the ILOGICS Arduino SDK. Each protocol has its own initialization and request-handling functions and its own HMI address format, so choose the section for a protocol your HMI supports. Channels and wiring are covered in Wiring the HMI. Screen setup and result checks are covered in Building the HMI Screen and Checking Operation.
Follow the installation steps below if this is your first time. After installing, you can use the simple example at the end of the protocol page you choose.
In the board selection window, set BOARDS to the product name and PORTS to the COM number of the connected cable. For other products' cables and drivers, see Connect the Product and Find the COM Port.
The COM port for uploading is separate from Serial1, which is used to communicate with the HMI.
