MIPI Camera on STM32N6

[Danilo Frigerio]

Hi everyone,

I'm working on a project with an AR0144 image sensor connected to CSI2. (STM32N6)
I have a question: if I use PIPE0 without any ISP processing of ROW10 data from the sensor to memory, do I still need to use ISP?
Do I need to initialize it? ISP_Init(...)

Thanks,

Danilo

Hi @Danilo Frigerio,

If you use PIPE0, there is no need to use or initialize the ISP pipeline because Pipe0 can only perform data dumping without any post-processing (It is only used to dump the stream received from the sensor as is). The ISP pipeline is exclusively used with PIPE1 and PIPE2 to perform image processing tasks.

You can refer to Application Note AN6211, specifically section 5.1 Configuration for RGB sensors

and also consult the Reference Manual RM0486, specifically section 39 Digital camera interface pixel pipeline (DCMIPP)

where the pipelines are described in detail.

Thanks.
