Hello Friends.

I want to connect the camera to the STM32F429 Discovery. I need to use DCMI module but I can't use with LTDC hardware. Because LTDC with DCMI using some common pins.(For example; PA4 = DCMI_HSYNC=LTDC_VSYNC)

How do I use the DCMI and LTDC hardware simultaneously?

You clearly can't use them ''simultaneously'', you need to look for a board with a higher pin count device.

I don't know what is *the* camera.

AFAIK, DMCI can deal with synchronization embedded into data (see RM).

If the camera is compatible, you still have a chance to make LTDC and DMCI working together, without DMCI_HSYNC.

hi,

I use the OV9655 camera module. The camera doesn't work without the HSYNC and VSYNC signals.

I have to use the camera with the software interface.
