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.
