如何让flag=1，1时 蜂鸣器每隔5秒响一秒 不用延时函数
在死循环里判断一下时间。

if sec == 0:

有关视频录制的问题
我想让智能车运动的时候顺便录制视频，可每次视
频录制完了车子也会停下来，怎么才能使视频录制完之后车子保持运动？

虚拟串口如何得到int型数据？
想通过虚拟串口接收int数据，但是以下代码却得不到想要的结果。本来应该是发送1，led灯会亮，但是实际上却不行
代码：
import sensor, image, time, ustruct
from pyb import USB_VCP,LED
green_led = LED(2)
red_led = LED(1)
usb = USB_VCP()
sensor.reset() # Reset and initialize the sensor.
sensor.set_pixformat(sensor.GRAYSCALE) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QVGA) # Set frame size to QVGA (320x240)
sensor.skip_frames(time = 2000) # Wait for settings take effect.
while(True):
if USB_VCP.any():
cmd = usb.readline().decode().strip()
val = int(cmd)
if (val == 1):
green_led.on()
当脱机运行人脸识别代码，LCD屏无任何反应且不能实现识别，重新将摄像头与电脑连接，发现main代码全都乱码。要怎么解决？
这个是存放在SD卡里的LCD代码
# LCD显示例程
#
# 注意：要运行这个例子，你需要一个用于OpenMV的LCD扩展板。
#
# LCD扩展板允许您在运行时查看您的OpenMV Cam的帧缓冲区。
import sensor, image, lcd
sensor.reset() # 初始化sensor
sensor.set_pixformat(sensor.RGB565) # or sensor.GRAYSCALE
#设置图像色彩格式，有RGB565色彩图和GRAYSCALE灰度图两种
sensor.set_framesize(sensor.QQVGA2) # 128x160大小的特定液晶屏。
lcd.init() # 初始化lcd屏幕。
while(True):
lcd.display(sensor.snapshot()) # 拍照并显示图像。
为什么 每次录制视频的时间都会少呢？哪位大佬帮忙看看 设置的是录制15个小时 出来每段视频只有20分钟 共30段视频
你这个rtc我看着不知道什么意思，如果要录制15小时, 可以用millis()判断.

sensor.reset() # Initialize the camera sensor.

sensor.set_framesize(sensor.QVGA) # or sensor.QQVGA (or others)
sensor.skip_frames(time = 2000) # Let new settings take affect.
clock = time.clock() # Tracks FPS.
pyb.LED(RED_LED_PIN).on()
sensor.skip_frames(time = 2000) # Give the user time to get ready.
pyb.LED(RED_LED_PIN).off()
pyb.LED(BLUE_LED_PIN).on()
m = mjpeg.Mjpeg("example.mjpeg")
print("You're on camera!")

while (pyb.millis()-start) < 15*60*60*1000:
clock.tick()
m.add_frame(sensor.snapshot())
print(clock.fps())
