引脚配置

使用jetson-io tool配置引脚：

sudo /opt/nvidia/jetson-io/jetson-io.py

选择“Configure Jetson 40pin Header”:

"Configure header pins manually":

配置15、33针脚发送PWM信号：

32引脚有坑。

保存设置并重启生效：

接线

1号舵机 VCC接2号针脚5V电压，GND接6号针脚GND，Signal接15号针脚PWM控制信号

2号舵机 VCC接4号针脚5V电压，GND接14号针脚GND，Signal接33号针脚PWM控制信号

# set mode to BOARD, pins are by numbers on board
GPIO.setmode(GPIO.BOARD)

# define output pin
output_pin = [15, 33]

# GPIO setup
GPIO.setup(output_pin, GPIO.OUT)

# start
servo=GPIO.PWM(output_pin[0], 50)
servo.start(0)
sleep(1)

# move left
servo.ChangeDutyCycle(5)
sleep(1)

# move right
servo.ChangeDutyCycle(12)
sleep(1)

# stop and cleanup
servo.stop()
GPIO.cleanup()
