STM32 as Modbus Master via RTU (RS-232/485) or TCP/IP,

[SKhan.21]

I want to read the analog value from an external Modbus device (Slave- connected via RS232/RS485/TCP-IP) to STM32F446RE or STM32H7XX (as Modbus Master).

Modbus Slave device could be any sensor or device that supports MODBUS protocol

Modbus Master (STM32)

Kindly help me with the coding, as I am new to STM32 microcontrollers.
