ov426寄存器配置

OV426是一款常用的CMOS图像传感器，它包含了一系列的寄存器用于设置其工作模式、像素格式、曝光时间等参数。寄存器配置通常涉及到以下几个部分：

1. **启动寄存器**：初始化摄像头，如设置分辨率、帧率、数据格式等。
- `CTRL0`寄存器：用于设置基本控制参数，比如像素大小、行周期和行计数。
- `CTRL1`寄存器：用于更详细的控制，如数据速率选择、中断模式等。

2. **定时器寄存器**：管理曝光时间和读取时间。
- `TIMER0`和`TIMER1`：分别设置全局定时器和行定时器的值，用于确定曝光时间和数据采集速度。

3. **命令寄存器**：执行特定操作，如开始/停止视频捕获。
- `CMD`寄存器：发送命令序列到传感器，例如开始一次拍照或开始连续拍摄。

4. **状态寄存器**：查看当前设备的工作状态。
- `STATUS`：可以查询传感器的状态信息，如是否正在捕获、是否有错误发生等。

5. **地址寄存器**：可能用于I2C或SPI通信中，调整传感器的寻址。

配置OV426时需要参考具体的规格文档，通常使用配套的SDK或驱动程序提供的API来进行，确保正确的寄存器写入顺序和数据格式。操作不当可能会导致硬件损坏或无法正常工作。
