1.写在前面
板子比较脆弱，尤其是排线（就是连着摄像头、显示屏的那两根软线），一旦固定好了，不要来扭动

2.组装
2.1 螺母（那几个白色塑料的小圈）本身比较紧，建议先用螺丝拧一下，后面好拧
2.2 安装摄像头的时候一定要把排线的卡扣抠起来，再插入排线，再把卡扣按下去，完成安装
2.3 先吧螺丝拧一下螺母，固定一下（不要拧紧）
2.4 摄像头固定孔对号螺丝，拧紧
2.5 同步骤2.2安装好显示屏

3。安装 MaixPy IDE

3.1 下载

提取码：ri1t

3.2 安装

4.连接板子
4.1.用usb插到电脑
4.2.打开电脑设备管理器，查看端口号，比如USB-Serial-Port（COM4），那说明你连接的是你的com4端口。
4.3.打开 MaixPy IDE，点击工具--选择开发板-->Sipeed Maix Bit（With Mic）
4.4.点击左下角的连接（像链条）符号，选择4.2步骤中查到的端口号，连接成功后左下角的圆圈符号变成红色。

5.运行代码
点击左下角的绿色圆圈符号，会运行当前默认打开的helloworld代码，会在电脑上和lcd屏幕上显示

这是默认的helloword代码，解释的很到位，看不懂可以翻一下后面的英语注释

import sensor, image, time, lcd
lcd.init(freq=15000000)
sensor.reset() # Reset and initialize the sensor. It will
# run automatically, call sensor.run(0) to stop
sensor.set_pixformat(sensor.RGB565) # 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.
clock = time.clock() # Create a clock object to track the FPS.
while(True):
clock.tick() # Update the FPS clock.
img = sensor.snapshot() # Take a picture and return the image.

专题1：如何在屏幕中做标记？

import sensor, image, time, lcd

sensor.reset() # Reset and initialize the sensor. It will
# run automatically, call sensor.run(0) to stop
sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)

clock = time.clock() # Create a clock object to track the FPS.
while(True):
clock.tick() # Update the FPS clock.
img = sensor.snapshot() # Take a picture and return the image.
img.draw_line(50,50,150,50,(255,255,255),2)
lcd.display(img) # Display on LCD
print(clock.fps()) # Note: MaixPy's Cam runs about half as fast when connected
# to the IDE. The FPS should increase once disconnected.

上句中的核心语句是
img.draw_line(50,50,150,50,(255,255,255),2)

img是image图像的缩写
draw line就是划线
6个参数，前面4个分别是两个端点的xy坐标，第五个是颜色（三个分量分别表示rgb），第6个是粗细

同理，还有draw_circle绘制圆形等函数，
在软件中输入img.draw。。后，它会提示所有的相关函数，根据需要选择即可。

专题2，如何标记色块

import sensor, image, time, lcd
lcd.init(freq=15000000)
sensor.reset() # Reset and initialize the sensor. It will
# run automatically, call sensor.run(0) to stop
sensor.set_pixformat(sensor.RGB565) # 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.
clock = time.clock() # Create a clock object to track the FPS.
while(True):
clock.tick() # Update the FPS clock.
img = sensor.snapshot() # Take a picture and return the image.
green_threshold = (0, 80,-70, -10,-0,30)
blobs = img.find_blobs([green_threshold])
if blobs:
for b in blobs:
tmp=img.draw_rectangle(b[0:4])
tmp=img.draw_cross(b[5], b[6])
c=img.get_pixel(b[5], b[6])
lcd.display(img) # Display on LCD
print(clock.fps()) # Note: MaixPy's Cam runs about half as fast when connected
# to the IDE. The FPS should increase once disconnected.
