Hello. Thanks always for the help
This time I have acquired a OV7670 camera with FIFO
https://www.openimpulse.com/blog/wp...oadables/OV7670-CMOS-VGA-Camera-Datasheet.pdf
and I am trying to control it with a STM32 nucleo and see it on a TFT LCD.
However I got this:

I am wondering why? Anybody with experience with this camera can give me some word of advice? perhaps you had the same problem and solved it?
I am guessing the problem relies on the initialization process (which seems quite complicated) My main suspicion is that the camera clock initialization is not being done right.
Also I read that the CLK pin of the camera needs pulling up resistor but with a STM32 nucleo it seems it does not.
Anyway, any comment advice or help is greatly appreciated

 

Just answering my own question in case someone needed

Revise the speed of the i2C interface. Many people say that the mbed libraries for i2c dont work for this but this is not true. They work. You just have to set them at the correct speed.

 

Hi!
I'm trying to do a digital camera with a STM32F446RE and the OV7670 without FIFO. Gotta save images and video into a SD card (using the slot from the TFT) an then send it through Bluetooth module. I was wondering if I could take a look at the code you made, it would be so helpful.

Regards and thanks in advance.
