Hello everybody
I am a student trying out some things with the evaluation board STM32F769I-EVAL.
First, I think it is important to say that I have nearly no experience with STM controllers.
So, let's look at my problem. The main aspects I am looking at, are camera, display and JPEG encoding. In the STM32CubeF7 firmware package, I found two interesting examples - DCMI_CaptureMode which continuously stream the camera image to the display, and JPEG_EndocingFromFLASH_DMA, I think that is self-explaining.
I tried to combine both to be able to save a camera image converted to JPEG to an SD card. In doing so, I came across one main problem - both programs use the same DMA stream (DMA2 stream1). I tried to change the stream but, obviously, it is not that easy.
Does anyone know what steps are to be taken to properly change the DMA stream? Can only specific streams handle the camera, for example?
Thanks for your answers, regards
Resa
