老规矩记录代码，真怕什么时候mbed崩了

#include "mbed.h"
 
AnalogIn analog_value1(A0);
AnalogIn analog_value2(A1);
DigitalIn mybutton(D7);
 
DigitalOut led(LED1);

int main() {
    float meas1,meas2;
    int key;
    
    printf("\nAnalogIn example\n");
    
    while(1) {
        meas1 = analog_value1.read(); // Converts and read the analog input value (value from 0.0 to 1.0)
        meas1 = meas1 * 3300; // Change the value to be in the 0 to 3300 range
        meas2 = analog_value2.read(); // Converts and read the analog input value (value from 0.0 to 1.0)
        meas2 = meas2 * 3300; // Change the value to be in the 0 to 3300 range
        key = mybutton.read();
        printf("measure = %.0f mV, %.0f mV, %d\n", meas1, meas2, key);
        if (meas1 > 2000) { // If the value is greater than 2V then switch the LED on
          led = 1;
        }
        else {
          led = 0;
        }
        wait(0.2); // 200 ms
    }
}

分别是Y轴，X轴，按键1是抬起，0是按下，看来上拉了

看上去很高级的样子啊
