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
