              @lin ar0234是黑白的sensor,你可以直接使用sensor输出的图像做算法计算即可。

                      @lin 如果i2c用的总线没有配置错误,需要检查一下硬件连接是否正确,比如供电、fpc排线方向、poweron那个pin的配置。

                                @lin i2c 、vcc都做了电平转换为3.3v。enable端不做电平转换直接由底板(1.8V)引出连接给相机,会导致无法正常工作吗?最低要求电压是多少?用i2cdetect -y 7检测不到设备

                                  我们的SYS_RSTn对应的是你的17,现在是NC的,我们内部有上拉,这样i2c应该直接就是通的。你是接到i2c-7上了吗?另外,你的fpc线方向有没有插反了?

                                        不好意思,我之前说的就是SYS_RSTn引脚的意思。

                                        拍一下你硬件连接的照片我看看。

                                            是的。 你这个camera3是对应的i2c-7吗? 如果无误,问题进展到这一步,我只能说上万用表,示波器量一下吧。先量供电,再量I2C。
