IS220PPRFH1A 为了规范地在Linux操作系统下操作，图像采集的电路部分需要图像采集应用程序相关的驱动程序进行支持。采集电路可分为多个功能模块分别进行驱动程序的编写，其中包括相机采集驱动（相应于VIP0进入数据后的操作）；控制驱动（相应于对Timer进行控制）；如果要根据外界环境改变相机工作状态，还需该部分驱动支持。采集驱动实现open，close方法。控制部分实现open，close，ioctl方法。自适应速率调整要实现open、 close、ioctl、read方法。在/DEV目录别建立设备节点，然后应用程序通过对设备节点进行操作。

应用程序的开发拟采用QT开发工具。应用程序拟设计成一个多线程程序，一个主线程，一个自适应调节参数线程，应用程序主要实现采集程序，停止，显示，配置，上传程序，分别对应于相应按钮。

采集按钮相应程序调用设备节点的open方法，open方法中对相应硬件进行配置，注册中断程序，启动Timer开始采集。

IS220PPRFH1A In order to operate under the Linux operating system, the circuit part of the image acquisition needs to be supported by the driver related to the image acquisition application. The acquisition circuit can be divided into several functional modules to write the driver program respectively, including the camera acquisition driver (corresponding to the operation of VIP0 after entering the data); Control driver (corresponding to the control of Timer); If you want to change the working state of the camera according to the external environment, this part of the driver support is also needed. Acquisition drive to achieve the open, close method. The control part implements the open, close, ioctl methods. Adaptive rate adjustment to implement open, close, ioctl, read methods. Create a device node in the /DEV directory, and then the application operates on the device node.

The development of the application is to use QT development tools. The application program is designed to be a multi-threaded program, a main thread, an adaptive adjustment parameter thread, the application program mainly realizes the acquisition program, stop, display, configuration, upload program, respectively corresponding to the corresponding buttons.

The corresponding program invokes the open method of the device node, configures the corresponding hardware in the open method, registers the interrupt program, and starts the Timer to start the collection.
