用openmv的IMU模块测振动的代码有吗

可是我想往建的文件存照片，它显示错误找不到路径

igkg

uos.mkdir（）

igkg

import sensor, image
import lcd

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.RGB565) # or sensor.GRAYSCALE
sensor.set_framesize(sensor.QQVGA2) # Special 128x160 framesize for LCD Shield.
lcd.init() # Initialize the lcd screen.
#lcd初始化

while(True):
lcd.display(sensor.snapshot()) # Take a picture and display the image.
#将图像显示在lcd中

igkg

image.save是读取，如何创建？

igkg

import sensor, image, tv
from PIL import Image

sensor.reset() # Initialize the camera sensor.
sensor.set_pixformat(sensor.RGB565) # or sensor.GRAYSCALE
sensor.set_framesize(sensor.QQVGA)
tv.init() # Initialize the tv.

while(True):
img = sensor.snapshot()
img.convert('L')
tv.display(img)

@kidswong999 在为什么我同时用I2C驱动IMU扩展版和P7,P8引脚驱动电机会报错，但是单独使用就不会。程序附上中说：

磁盘

有我加进去的

igkg

if语句后面加 :
