Working with STM32 and ultrasonic: using timer and interrupt to measure the distance
In the previous guide(here), we looked at the operation principle of how ultrasonic works and we used very crude code to measure the distance.…
Working with Ultrasonic Sensor and STM32
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…
