Is your feature request related to a problem? Please describe. I'm trying to use the OV2640 camera module on the NUCLEO-H743ZI2 board. However, the video driver for the DCMI peripheral doesn't exist (the driver for OV2640 does exist).

Describe the solution you'd like Development of the DCMI video driver to capture the images from a camera module.

TODO

[x] Update the stm32h7xx-pinctrl.dtsi files to include the DCMI pin configuration. See PRs: https://github.com/zephyrproject-rtos/hal_stm32/pull/204 and https://github.com/zephyrproject-rtos/hal_stm32/pull/205
[x] Initial version of DCMI driver on STM32H743 MCU. See PR https://github.com/zephyrproject-rtos/zephyr/pull/71462
[x] Create a sample application using the DCMI driver.
[ ] Merge PR https://github.com/zephyrproject-rtos/zephyr/pull/71463

Hey @CharlesDias I was going through your changes to add the DCMI driver . Is there a possibility that we can add camera support also along with video support in this PR itself . I would like to contribute to that as I am also currently working on DCMI support for OV2640 by myself

CharlesDias commented 5 months ago

Hi, @adityaganesh2k. Glad to know there's someone working on this too! I can open the PR as a draft to get help from you and others. What do you think?

Which board are you using?

adityaganesh commented 5 months ago

Yeah that would be great i am working with a Weact Studio board based on stm32h750vbt6 . Link for the board:-https://evelta.com/weact-studio-stm32h750-development-board/. I actually made the same changes as your commit on a branch of mine but my branch is forked from v3.6 of zephyr where iam getting a compilation error . My board files and the changes to add dcmi looks fine to me . If you could share me your email id we can correspond there

Hi, @adityaganesh.

Sure. My e-mail is charlesdias.cd@outlook.com. Also, if you prefer, send me a message on LinkedIn https://www.linkedin.com/in/charles-dias-m-sc-6ab50527/

I opened the PR https://github.com/zephyrproject-rtos/zephyr/pull/71462 related to the STM32 DCMI driver. I tested with the Weact Studio STM32H743 board and worked fine.

@CharlesDias Do you think this point can be closed ?

@CharlesDias Do you think this point can be closed ?

Hi, @erwango. The sample application using the DCMI driver hasn't been merged yet, PR #71463 . Is this a reason not to close the issue? What do you think?

erwango commented 3 months ago

ok, sure. Maybe you want to update the TODO list above then.
