This category covers the complete Modbus implementation series for STM32 microcontrollers, including both Modbus RTU and Modbus TCP. The tutorials walk through everything from protocol basics to practical implementation — configuring the STM32 as both a master and a slave, reading and writing coils, holding registers, input registers, and discrete inputs. Modbus RTU uses serial communication over UART, while Modbus TCP uses Ethernet. Both are covered here in detail.
