}代码说明 Arduino代码相当简单。它不需要任何库即可工作。草图首先声明连接到 DRV8833 控制引脚的 Arduino 引脚。
// Define the control inputs
#define MOT_A1_PIN 10
#define MOT_A2_PIN 9
#define MOT_B1_PIN 6
#define MOT_B2_PIN 5代码的设置部分初始化硬件。它将所有电机控制引脚配置为数字输出并将其设置为低电平以最初禁用两个电机。然后它以 9600 的波特率初始化串行通信。
void setup(void){// Set all the motor control inputs to OUTPUTpinMode(MOT_A1_PIN, OUTPUT);pinMode(MOT_A2_PIN, OUTPUT);pinMode(MOT_B1_PIN, OUTPUT);pinMode(MOT_B2_PIN, OUTPUT);// Turn off motors - Initial statedigitalWrite(MOT_A1_PIN, LOW);digitalWrite(MOT_A2_PIN, LOW);digitalWrite(MOT_B1_PIN, LOW);digitalWrite(MOT_B2_PIN, LOW);// Initialize the serial UART at 9600 baudSerial.begin(9600);
}代码的循环部分生成一个固定的运动序列来演示电机模式。
它首先逐渐增加电机的速度然后进入全速再次减速并反转方向到全速最后停止。
// Ramp speed up.
for (int i 0; i 11; i) {spin_and_wait(25*i, 25*i, 500);
}
// Full speed forward.
spin_and_wait(255,255,2000);// Ramp speed into full reverse.
for (int i 0; i 21 ; i) {spin_and_wait(255 - 25*i, 255 - 25*i, 500);
}// Full speed reverse.
spin_and_wait(-255,-255,2000);// Stop.
spin_and_wait(0,0,2000);停止后它演示了两轮机器人底座的转弯操作其中一个轮子向前移动另一个轮子向后移动导致机器人转动。在演示了所有这些动作之后循环重复。
// Full speed, forward, turn, reverse, and turn for a two-wheeled base.
spin_and_wait(255, 255, 2000);
spin_and_wait(0, 0, 1000);
spin_and_wait(-255, 255, 2000);
spin_and_wait(0, 0, 1000);
spin_and_wait(-255, -255, 2000);
spin_and_wait(0, 0, 1000);
spin_and_wait(255, -255, 2000);
spin_and_wait(0, 0, 1000);此草图中使用了三个用户定义的函数
set_motor_pwm()set_motor_currents()spin_and_wait()该功能使用 PWM 和方向逻辑设置电机通道上的电流。如果该值为负则电机沿一个方向旋转。如果值为 0 或正则电机停止或向另一个方向旋转。
set_motor_pwm()pwmpwmvoid set_motor_pwm(int pwm, int IN1_PIN, int IN2_PIN)
{if (pwm 0) { // reverse speedsanalogWrite(IN1_PIN, -pwm);digitalWrite(IN2_PIN, LOW);} else { // stop or forwarddigitalWrite(IN1_PIN, LOW);analogWrite(IN2_PIN, pwm);}
}该函数使用前面的函数来设置两个电机上的电流。它将每个电机的当前PWM值打印到串行监视器。
set_motor_currents()void set_motor_currents(int pwm_A, int pwm_B)
{set_motor_pwm(pwm_A, MOT_A1_PIN, MOT_A2_PIN);set_motor_pwm(pwm_B, MOT_B1_PIN, MOT_B2_PIN);// Print a status message to the console.Serial.print(Set motor A PWM );Serial.print(pwm_A);Serial.print( motor B PWM );Serial.println(pwm_B);
}该函数设置速度并等待指定的时间量然后再移动到下一个命令。它使用该函数为两个电机设置PWM值然后等待指定的毫秒。

{set_motor_currents(pwm_A, pwm_B);delay(duration);
}
