例程讲解-03-copy2fb把图像复制到framebuffer
# 复制图像到 framebuffer.
#
# 这个例子展示了如何导入和粘贴一个图像到 framebuffer
import sensor, image, time
# 仍然需要初始化 sensor
sensor.reset()
# 设置 sensor
sensor.set_contrast(1)
sensor.set_gainceiling(16)
# 设置sensor的 pixel format
sensor.set_framesize(sensor.QQVGA)
sensor.set_pixformat(sensor.GRAYSCALE)
# 导入 image
img = image.Image("/example.bmp", copy_to_fb=True)
# 添加画线的代码
# img.draw_line(...)
# Flush FB
sensor.flush()
# Add a small delay to allow the IDE to read the flushed image.
time.sleep_ms(100)
