            @canglin 这个你设置不了,除非你使用SDA模式,bypass掉我们mcu的控制。

                mipi信号的clock是数据速率的一半。
                H-Blank和V-Blank跟具体的roi设置和帧率设置有关系。不过我觉得你fpga接收只要设置好最小可能值就行了。
                H-blank:180
                V-blank:25

                          @veye_xumm 我用示波器量了下,mipi 的clk和数据波形

                                  @veye_xumm 如果帧率配置成30fps,其他参数会修改吗

                                      降低帧率的话,V-Blanking会加大。比如默认是1080p@60fps,对应V-Total=V-Active+V-Blanking=1080+25;那么配置成30fps的时候,V-Total会配置为原来的2倍,增加的全部会加到V-Blanking中。

                                        @veye_xumm 您好,麻烦问下,0x840寄存器读出来的数怎么推算csi_clk,我刚才读了下这个数,是(0x9878)38Mbps
