    • 怎么能看到调用的函数更底层的写法?

      例如
      tv.init(triple_buffer=False) # Initialize the tv.
      tv.channel(8) # For wireless video transmitter shield

    • 得到像素RGB565的颜色数据

      ![0_1619486634319_21T5![W}ED`R1TRFM5K12KX.png](正在上传 100%)
      image.grayscale_to_rgb(grayscale_value) 这个函数返回是RGB888的颜色数据,想要得到RGB565的颜色数据,自己用函数将RGB88转RGB565得到的颜色数据会失真

      OpenMV3串口通讯 按教程用TTL转USB做的,串口助手收不到信息,请问会是哪里出了问题,程序用的是例程,波特率也调过了。
