External interrupts are a powerful feature of microcontrollers that allow you to respond to external events (e.g., button presses, sensor triggers) without constantly polling the input pins. This tutorial demonstrates how to configure and use extern…
In this STM Programming Tutorial we will use hal read function to read the button state and turn on or off a LED according to whether the button is low(when pressed) or high(not pressed). We will be using the STM32Cube IDE which uses internally GCC…
We showed earlier how we can use the hal toggle function to blink a LED with STM32 Nucleo64 board. In this continued STM32 programming tutorial we will use the HAL set and reset write function to blink a LED with the STM32 Nucleo-64 board. The bas…
In the previous STM32 Nucleo-64 tutorial , I showed how to simulate the nucleo board in Proteus electronics and microcontroller simulation software.In that guide, I also gave the download link for downloading the STM32 Nucleo-64 simulation model. …
The Keil MDK (Microcontroller Development Kit) and the GCC Compiler for ARM are both widely used tools for developing embedded applications, particularly for ARM Cortex-M microcontrollers. However, they differ significantly in terms of licensing, …
I had heard about the STM32 microcontroller many years ago but had never chance to learn about it. Yesterday I created a simulation model of STM32 nucleo board in Proteus. The nucleo board is based on the STM32F401RE microcontroller. I tested it wit…
This article presents a MOSFET-based H-bridge motor driver circuit for controlling motor speed and direction, ideal for robotics and motor-driven applications. It utilizes four N-channel MOSFETs (IRF540N) and two P-channel MOSFETs (IRF9540) with PW…
