Examples programs for STM32F4Discovery. These examples were written while I was exploring STM32F407VGT microcontroller. I think this is may be helpful somebody.

Bug in Ultrasonic Sensor Example

I found an interesting bug in ultrasonic sensor example and it cost me a sensor :). In program, if duration over 30000 it get returns to loop. But this cause to be sending of 10us trigger pulse over and over without break0. Due to this, tx transducer becomes hot and I think its driver burning. If you somehow forget to connect echo pin to right mcu input, sensor burns.
