This is another tutorial in the Modbus series and today we will see how the STM32 as master Writes multiple coils and Holding Registers.
This section provides step-by-step STM32 tutorials and tested code for learners ranging from beginners to experts. Programming is demonstrated in STM32CubeIDE using both HAL and LL drivers, making the examples easy to follow and adapt. The coverage spans GPIO, ADC, UART, timers, PWM, I2C, SPI, CAN, Ethernet, DMA, memories, displays, sensors, and many other peripherals—ideal for anyone looking to gain practical experience and develop reliable hardware projects.
