LCD的使用

视频教程7 - LCD显示屏的使用：OpenMV使用LCD显示屏 | 星瞳科技

在IDE中运行下面的代码：

此代码适用于4.5.1至最新的固件版本。

# 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。
#
# 此代码适用于4.5.1至最新的固件版本。import sensor
import displaysensor.reset()  # 初始化sensor
sensor.set_pixformat(sensor.RGB565)  # or sensor.GRAYSCALE
sensor.set_framesize(sensor.QQVGA2)  # 128x160大小的特定液晶屏。
# 初始化lcd屏幕。
# 注意：如果支持，可以使用 DAC 或 PWM 背光控制器来控制背光强度：
#  lcd = display.SPIDisplay(backlight=display.DACBacklight(channel=2))
#  lcd.backlight(25) # 25% intensity
# 否则，将使用默认的 GPIO（开on/关off）控制器。
lcd = display.SPIDisplay()while True:lcd.write(sensor.snapshot())  # 拍照并显示图像。

效果如下图：

以下代码适用于4.4.3及之前的固件版本。

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。

无线传输图像

无线传输小球坐标

import sensor, image, time, network, usocket, sys, jsonSSID ='OPENMV_AP'    # Network SSID

与传输图像类似，浏览器输入192.168.1.1:8080
就可以获得json数据

如果想在自己的代码中获得数据，只需要GET 192.168.1.1:8080
就会获得JSON。

例如python：

import requests
r = requests.get('192.168.1.1:8080')

只传输一张图片
