Hi,I try to use your OV5640 board with your OV5640 driver in STM32H747 BSP in JPEG mode.The problem is that the FPS drop to 1 or 2 even at low resolution QVGA.Can you show me what registers needed to be modified to make it work correct since your dri...

What would happen to the microcontroller if during running normally then suddenly the boot_0 pin switched to high?in my case and due some voltage spike the boot_0 pin state switched to high for very short time nano seconds. most of the time its ok bu...

That is not the problem. the problem is how to configure the DMA if we dont know the image size. in jpeg the image size is un known.i dont want save it in file. i want to decode it and show it on display.

@Zaid1 Yes its possible to do it. i already converted YCbCr from DCMI to RB565 using DMA2D.you will need to do some processing to organize this lines to YCbCr MCU (Minimum Code Unit) to make it compatible for the DMA2D then feed them to DMA2D.For YCb...

@patrickschneider9 The main problem in 90 degree rotation with DMA2D is that it lacks the ability to decrement the destination address. there is an optimized way to rotate an image 90 degree with much better performance compared to software version.f...
