8/30/2014 · Library 30- Measure distance with HC-SR04 and STM32F4. by tilz0R · Published August 30, 2014 · Updated June 23, 2015. I have at least 10 HC – SR04 sensors at home so I decided to made a library for it. This sensor can measure distance between 2cm and 4meters. It can produce about 40 measurements per second.
HC-SR04 Ultrasonic sensor and STM32 . Ultrasonic ranging module HC – SR04 provides 2cm – 400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules includes ultrasonic transmitters, receiver and control circuit. Today in this tutorial we are going to learn How to interface HCSR04 Ultrasonic sensor module with …

1/16/2020 · STM32 HC-SR04 Ultrasonic Distance Sensor – VN49. STM32 example of how to use HC-SR04 Ultrasonic Distance Sensor. In this video, we will be using Timer gated mode, Timer Update Interrupt, trigger and commutation interrupts, global interrupts, GPIO, LCD and I2C.
8/19/2014 · Taking the speed of sound as a constant of 343m/s (it varies with temperature and pressure!), the distance can be easily calculated as TimeOfFlight*343. In the above example, this will be: Distance = 1.286e-3*343 = 0.441m = 44.1cm. Voila! A simple way to calculate distance using the SR04 sensor.
There is the problem of matching the 5 V world of the HC – SR04 to the 3.3 V of the STM32 . I started by using the safe option of a couple of FET level shifters. Downloads: Archive of Arduino sketchbook ping32int – using interrupts- (1st February 2016) Archive of Arduino sketchbook ping32capture – using timer capture – (1st February 2016), Understand the way to use HC -SRF04 on STM32 (Nucleo board) and mBED. HC -SRF04 is an ultrasonic ranging module provides 2 cm – 400 cm non-contact measurement function, the ranging accuracy can reach to 3 mm. Personally I got a good result in the range from 3,5 cm to 3,8 m. The Electric Parameters are in the image below.
HC-SR04 with STM32 gives unexpected values. Ask Question. Asked 3 years ago. Active 3 years ago. Viewed 1k times. 0. On an Arduino it is easy to get an HC – SR04 ultrasonic sensor getting to work. However, on my STM32 (F103C8T6) I get strange values. I assumed I connect it correctly, since I get values on the trigger pin.
