Explore step-by-step STM32 Modbus tutorials using HAL. Learn how to set up RS-485 communication, configure devices as Master or Slave, read/write holding and input registers, and handle real-time data exchange using Modbus.
Modbus has become a standard communications protocol in industries, and is now the most commonly available means of connecting…
Modbus #1. STM32 Master Reads Holding and Input Registers
How to use the STM32 as the master requesting the data from the holding registers and input registers from the slave device..
Modbus #2. STM32 Master Reads Coils and inputs
This is second tutorial in the Modbus series and today we will see how to use the STM32 as the master to read the coils and Discrete inputs.
Modbus #3. STM32 Master Writes single Coil and Holding Register
Today in the modbus series we will see how to use the STM32 as the master, which will Force a single coil and Preset a Holding Register.
Modbus #3.1 STM32 Master Writes Multiple Coils and Registers
This is another tutorial in the Modbus series and today we will see how the STM32 as master Writes multiple coils and Holding Registers.
Modbus #4. STM32 as Slave || Read Holding and Input Registers
This tutorial will cover how the STM32 as a modbus slave, that will send a response to the queries regarding reading registers…
