This is a Modbus RTU (RS-485) device on NuMaker-IoT board running Mbed OS.
https://os.mbed.com/teams/Nuvoton/code/ ... us-sample/
The example should work for these NuMaker IoT boards which have Mbed OS certified, such as NuMaker-IoT-M487 and NuMaker-IoT-M467.
It is recommended to use Mbed Studio as a development tool. Register an Mbed OS account to use Mbed tools for free (https://os.mbed.com) then download Mbed Studio and install it (https://os.mbed.com/studio)
Please refer post to create a new project by importing the Modbus example.
Enjoy it.
