How to use modbus over serial line for stm32
no vote
We are developing
a hardware and software of master and client device for use security system. We use 210 board based on ARM CORTEX 8 CPU
module for master device. We use software
with android application for graphical design of the security system and
combine this master device with client device based on stm32 microcontroller by
serial interface for security system of builder. In client device, we combined
some sensors that moving sensor, smoking, light ext.. We want to use modbus protocol for serial
data communication . So How to use Modbus over serial line for the stm32f101 microcontroller Help to me. please. We need some example test source code of stm32f101 with Modbus protocol.
