Modbus Library without FreeRTOS

5 replies

Hi,
I am working with an STM32 microcontroller (STM32 C0 & STM32H5 series) and want to implement Modbus communication without using FreeRTOS . Most examples I found are based on FreeRTOS, but I need to handle Modbus protocol in a non-RTOS environment.
Are there any recommended Modbus libraries that can work without an RTOS?

Hello @himani ,

You need also to specify which Modbus flavor? RTU? TCP/IP?

Knowing that STM32C0 has no ETH interface.

See for example these links for Modbus RTU: https://github.com/urands/stModbus
