I would like work easly and quickly camera with DCMI on STM32F407.

Does anyone know sample source code on this system?

I hope the program work parfect when I write to STM32 byEWARM.

Actually, I already have a STM32F407 Board on my desk(not discovery kit) and OV7670 and OV7725, but unfortunately doesn't work.

Surely myy coworker and I ready other threads, but  it seems anyone doesn't work.

If anyone help us to suggest DCMI code with something camera,

I will try to write it on my STM32F407 and get the camera.

thank you.

Why not simply download code examples for DCMI from st.com ?

Thank you for your reply.

How can I find the code?

Could you send me the URL?

DMA started to work step by step yesterday, yet Data Bus doesn't work completely.

Although I confirmed something image data from camera.

I bet, if you provide me to ST sample codes site, it'll work soon.

Thank you, clive1.

It'll be helpfull for me.

I haven't get the file before, that's why my program doesn't work.

Hi Nagano,

You can also refer to the STM32Cube based application as follows:

\Projects\STM324xG_EVAL\Applications\Camera\Camera_To_USBDisk

 

You've just to download the STM32Cube_FW_F4_V1.3.0 from this

http://www.st.com/web/en/catalog/tools/PF259243#

.

Regards,

Heisenberg.

Hello, Heisenber.

It's first time to use STM32 seriese in my office so that we don't have enough skills.

Finally, I got a color bar image in this morning, but I haven't check camera image yet.

I have still some proberem that is VGA size, something like that.

It'll be find good way soon.

I'll check camera image from now.

Thank you.

Thank you everyone.

I got a actual pic color throuh a lense, however I stiil have a problem.

How can I send to VGA data to external SRAM(MT45W4MW16PCGA)?

Normal DMA uppler limit is 65536 times with 4 byte setting.

(I mean ''DMA_Memory_Data_Size''.)

Therefore, it's not enough to send for (640 x 480 x 2bytes(color bytes) = 614400).
