Servo motor 69

Library 42- Control RC servo with STM32F4

Library 42 allows you to simple connect and interface RC servo motors with STM32F4. They are small, cheap motors, commonly used for RC (Radio Control), small scale robotics and more. Servos are really simple to interface. They expect 50Hz signal on the input. According to the pulse length (duty cycle) they rotate between 0 and 180 degrees. If signal has 1ms pulse length, motor rotation will be 0 degrees and if signal has 2ms length, then it will have 180degrees rotation. Any pulse length...
