有没有接其他电路？OpenMV是如何供电的，供电接的哪个引脚？

@openmv萌新 如果是两个不同的指令怎么区别？

import sensor, image, time sensor.reset() # Reset and initialize the sensor. 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() # img这里是彩色 img = img.to_grayscale() # img这里是灰色 print(clock.fps())

来自星瞳实验室APP: memory error大佬帮忙看看 谢谢。 https://forum.singtown.com/topic/1005

请运行hello world http://book.openmv.cc/example/01-Basics/helloworld.html

你是怎么解决的啊

神经网络目前教程还不完善（主要是机器学习本来就是个很大的坑，没有几年学不了），我们还在完善如何训练网络的教程。
