An open-source Modbus protocol stack based on FreeModbus that adds a master mode to the traditionally slave-only library, supporting RTU, ASCII, and TCP modes. It runs on bare-metal or RTOS environments (RT-Thread, FreeRTOS, UCOS) and allows master and slave to operate concurrently in the same stack.

Use cases

  • implement a Modbus master on an STM32 microcontroller
  • add Modbus RTU master functionality to an embedded firmware project
  • run Modbus master and slave on the same device
  • port a Modbus protocol stack to FreeRTOS or RT-Thread
  • poll holding registers and coils from Modbus slave devices
  • build an industrial sensor gateway with Modbus TCP

When to choose

  • you need an open-source Modbus master for embedded C projects
  • you want master and slave modes in a single protocol stack
  • you target RTOS or bare-metal microcontroller environments
  • you need blocking or non-blocking request modes with configurable timeouts

When to avoid

  • you need a high-level Modbus library on Linux or Windows desktops
  • you require a commercially supported or certified protocol stack
  • you need Modbus master in a language other than C
  • you want a maintained library with active releases and clear licensing
