      引脚号 名称 说明
      1 Trigger In 触发输入,兼容2.5-3.3V
      2 GND
      3 Strobe Out 闪光灯同步输出,2.5V

      关于J7的介绍只有这些,我想知道脚1,3的具体作用是什么,在什么场合下会使用到?

        说的CS-MIPI-SC132吧?
        在外触发模式的时候用到。 1脚是硬触发的输入,3脚用于同步补光灯,sensor曝光的时候会给出信号。

          好的,那么也就是说这个三脚的信号的时间就是曝光的时间,是吗?

            @robot 可以这样理解。

              @veye_xumm 您好我今天尝试了补光灯同步功能,我是用./cs_mipi_i2c.sh -w -f ledstrobe -p1 1
              命令开启的,返回的是w led strobe enable
              但是我在后续采集图像时并未抓到同步信号的脉冲,请问这一信号的使用有什么条件吗?

                @robot 你用的板子是树莓派吗?如果不是需要加-b参数指明 i2c bus. 最好读一下出来,验证是否配置进去。

                ./cs_mipi_i2c.sh -r -f ledstrobe

                  @veye_xumm 感谢您的回复,我使用命令读取是设置成功的,但是关于-b的问题我没有设置,我验证后再与您同步这一进展,谢谢

                    您好,我测试发现返回了NOT SUPPORTED!
                    但是按照手册应该是支持这一功能的吧?
                    另外您提到的-b命令的用法是什么样的,我添加了-b 7 到命令里面,但是失败了

                      你好,-f 后面要接函数名字。你按照下面这个试试。

                      ./cs_mipi_i2c.sh -w -f ledstrobe -p1 1 -b 7 
                      

                      另外这个函数不支持read。具体你可以看一眼这个脚本。

                      你给的信息太少,不知用的什么板子。所以bus number我也不太确定。
                      你可以试试读一下version。 能正确读到就说明这个i2c bus是对的。
