Measure distance with HC-SR04 Ultrasonic distance sensor on STM32F4xx devices - http://stm32f4-discovery.com/2014/08/library-30-measure-distance-with-hc-sr04-and-stm32f4xx.

Default pinout

There is not default pinout anymore. As of version 2.0, you can use unlimited HC-SR sensors connected to STM32F4xx device.

You just make sure that you use different pins for different sensors.

Pins are passed on TM_HCSR04_Init function.

I didn't tested that, but you might use the same ECHO pin for all sensors if you read sensor by sensor at a time. Do that by own risk!
