Serial Communication with Nodemcu

HI Pramod,

Which serial protocol does your MicroController use? In order to read data from it using a B&R controller, you’ll need:

  • A relevant serial interface (e.g. X20CS1020 for RS232 communication)
  • Software to interact with the serial interface

The library you’ll probably want to use is DVFrame. This library allows you to exchange data with serial devices.

Alexander gave a good explanation of how to get started with this library in a previous post. It’s in the context of RS485, but it may be relevant for you.
