ServoIn Class Library
This class library uses external interrupts with timer functions to read servos pulses on mbed input pins.
ServoIn Library usage example
#include "mbed.h" #include "ServoIn.h" DigitalOut led1(LED1); ServoIn servoIn1(p15); ServoIn servoIn2(p14); Serial pc(USBTX, USBRX); // tx, rx int main() { pc.baud(921600); //Fast baud rate while(1) { led1 = 1; wait(0.05); led1 = 0; wait(0.05); pc.printf("servo pulse: CH1=%5dus CH2=%5dus\r\n", servoIn1.read(), servoIn2.read()); } }
