1.显示英文

#MicroPython动手做（05）——零基础学MaixPy之LCD液晶屏

#测试程序之一：显示英文

import lcd

lcd.init()
lcd.draw_string(100, 100, "hello MicroPython!", lcd.RED, lcd.BLACK)

2.LCD液晶显示器彩条测试

#实验程序之二：LCD液晶显示器彩条测试

import lcd,image, time


lcd.init(type=1, freq=15000000)
# lcd.init(type=2, freq=20000000)
# lcd.init(type=1, width=320, height=240, invert=True, freq=20000000)

img = image.Image(size=(240,240))
img.draw_rectangle(0,0,30, 240, fill=True, color=(0xff, 0xff, 0xff))
img.draw_rectangle(30,0,30, 240, fill=True, color=(250, 232, 25))
img.draw_rectangle(60,0,30, 240, fill=True, color=(106, 198, 218))
img.draw_rectangle(90,0,30, 240, fill=True, color=(98, 177, 31))
img.draw_rectangle(120,0,30, 240, fill=True, color=(180, 82, 155))
img.draw_rectangle(150,0,30, 240, fill=True, color=(231, 47, 29))
img.draw_rectangle(180,0,30, 240, fill=True, color=(32, 77, 158))
img.draw_rectangle(210,0,30, 240, fill=True, color=(27, 28, 32))

lcd.display(img)

count = 500
while count > 0:
    t = time.ticks_ms()
    lcd.display(img)
    print(time.ticks_ms() - t)
    count -= 1

3.显示图片

import lcd,image,utime

lcd.init() #初始化LCD
lcd.clear(lcd.WHITE) #清屏白色

#显示字符
lcd.draw_string(110, 120, "Hello 01Studio!",lcd.BLACK, lcd.WHITE) #显示字符
utime.sleep(3) #延时2秒
lcd.rotation(1) #由于图像默认是240*320，因此顺时钟旋转90°。
#显示图像，必须先将01Studio.bmp文件发送到开发板才能正常运行
#发送方法：IDE菜单栏 -- 工具 --保存文件到开发板
lcd.display(image.Image("girl001.jpg"))

4.尝试拍一张照片

# generated by maixhub, tested on maixpy3 v0.4.8
# copy files to TF card and plug into board and power on
#MicroPython动手做（05）——零基础学MaixPy之LCD液晶屏
#MicroPython动手做（06）——零基础学MaixPy之单目摄像头
#测试程序之四：尝试拍一张照片

import sensor, lcd, image

print("init")
lcd.init(freq=15000000)
sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.set_vflip(1)
sensor.set_hmirror(1)
sensor.run(1)
sensor.skip_frames(40)
print("init ok")

path = "/sd/image_demo.jpg"
img = sensor.snapshot()
print("save image")
img.save(path)

print("read image")
img_read = image.Image(path)
lcd.display(img_read)
print("ok")

5.获取和显示实时帧数

#MicroPython动手做（06）——零基础学MaixPy之单目摄像头
#测试程序之四：获取和显示实时帧数

import sensor
import image
import lcd
import time
import gc

clock = time.clock()
lcd.init()
sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.set_vflip(1)
sensor.set_hmirror(1)
sensor.run(1)
sensor.skip_frames(30)
while True:
    clock.tick()
    img = sensor.snapshot()
    fps =clock.fps()
    img.draw_string(2,2, ("%2.1ffps" %(fps)), color=(0,128,0), scale=2)
    lcd.display(img)
    gc.collect()

6.录制一段视频

#【AI】运用MaixPy平台的Maixduino几个小项目
# 项目六：录制一段视频（30秒）
# 1. 将板子连接到计算机
# 2. 在 MaixPy IDE 顶部选择板：`Maixduino`
# 3. 点击下方的连接按钮连接板子
# 4. 点击下方绿色运行箭头按钮运行脚本！
