In this tutorial, we will learn to use HC-SR04 ultrasonic sensor with STM32 Blue Pill and program it using STM32CubeIDE and HAL libraries. At first, we will take a look at the ultrasonic sensor, then interface it with our STM32 Blue Pill and program it for contactless distance measurement using STM32CubeIDE.

In this tutorial, we’ll be discussing the interfacing of STM32 microcontrollers with HC-SR04 ultrasonic sensors using timer input capture mode with interrupts. I’ll also show you the HC-SR04 library (driver) that I’ve developed for STM32 microcontrollers and discuss how it works and how it’s been built in this way.

Today in this tutorial we are going to learn How to interface HCSR04 Ultrasonic sensor module with STM32. Working of hcsr04 is pretty simple and straight. The module emits an ultrasound at 40 KHz which, after reflecting from obstacle, bounces back to the module.

Jul 23, 2021 · This guide shows how to use the HC-SR04 Ultrasonic Sensor with the STM32F411 Nucleo-64 board using only registers level with GPIO polling mode. The ultrasonic sensor uses sonar to determine the distance to an object.

Look for the external pin number corresponding to PA6 in the circuit diagram as D12. This pin will be connected to the Echo pin of the ultrasonic sensor. In order to facilitate device connection, the external pin D11 adjacent to D12 is selected as the output to connect with Trig, so the corresponding pin PA7 of D11 is configured as GPIO output.

This circuit utilizes an STM32 Nucleo F303RE microcontroller to interface with multiple HC-SR04 ultrasonic sensors for distance measurement and provides visual feedback through an I2C LCD display and a WS2812 RGB LED strip.
