generic digital camera driver

In the first half of this year, I transplanted a Linux driver to a common vimicro camera on the market to an Embedded Development Board. The development environment is: OS: linux2.6.9 Compile: Cross 3.3.2 CPU: Intel PXA270 Camera type: vimicro zc301p + hv7131r The driver source code used is based on the free software s

This series is divided into 3-4 articles, because too many articles will be messy. V4l2 video drivers mainly involve the following knowledge points: Camera knowledge (You can view the chip manual provided by the camera manufacturer.) You need to know the features of the selected camera, including the access control method, configuration methods of various parame

The first time I bought something from a Japanese devil nnd, I was not happy with the sweat. It is a pity that a ghost camera does not support 2003 after it is purchased. I won't talk about why I bought a ghost camera. I don't need to talk about anything I bought now. Yesterday, Christmas was supposed to be cheaper, so I promised my girlfriend that I had bought her favorite

measure whether each pin of the camera is correctly connected to the chip before the development driver. Otherwise, the image will not be visible even if the code is correct. Mt9d111 is an image sensor chip with a CMOS interface. It can sense external visual signals, convert them into digital signals, and output them. We need to provide the

balanced, do not be anxious. Since the starting point was too high (to start with a generic driver), difficult to grasp the degree of certainty, and there is no basis for their own, so very depressed, but slowly, with the camera-driven understanding, realize that GM is actually very difficult, you need to the various camera
