The camera only displays pink

[PeterHonor]

I built with the latest version and then the camera just showed a pink color. With version 10.4.2 and Arduino Core 3.1.0 everything works fine.

hardware or configuration issue. impossible to diagnose unless someone else reports the problem

[josef2600]

no problem with me. it works. OV5640

[PeterHonor]

If I #define INCLUDE_I2C false then everything is ok. With version 10.4.2 and arduino-esp core 3.1.0 I don't have this problem. I think this is an I2C problem in arduino-esp core 3.1.1

[josef2600]

yes i heard it too, but i think s60sc has fixed it. it has been more than a week since the fix. you should download it.
and you have to say when you have connected other stuff to your board!

[PeterHonor]

@josef2600 : I just downloaded latest version 10.5.3. Nothing changes (I have nothing connected to my board)

[12:05:06.793 logSetup] =============== ESP-CAM_MJPEG 10.5.3 ===============
[12:05:06.795 boardInfo] Chip ESP32-S3, 2 cores @ 240Mhz, rev 0

[12:05:06.796 logSetup] Compiled with arduino-esp32 v3.1.1

If I replace ov5640 with ov2640 everything works fine. Then I discovered the problem is that the I2C address of the ov5640 is the same as the address of the SSD1306. If i change I2C address of SSD1306 from 0x3C to 0x3D (in periphsI2C.cpp) then I can see images from the camera, but I can't change any camera parameters. When I change I get a warning: feature not included:

[10:25:01.236 WARN updateStatus] Trying to config gainceiling but feature not included
[10:25:13.664 WARN updateStatus] Trying to config ae_level but feature not included
[10:25:14.686 WARN updateStatus] Trying to config ae_level but feature not included

In the end I had to #define INCLUDE_I2C false and everything is OK now, but no I2C

[josef2600]

when somebody say if you have anything connected to the board ,it doesn't mean just physically! mainly it means in the code.
on any code or board, you have to check the hardware and know what is connected to what. specially when you have connected a special device to your board, like a camera, never use the same i2c (or hardware) for another thing, like whatever you are using, to it. unless you have full knowledge of what you are doing and what the code is doing. for example, this code uses LEDC channel 1 and timer 1 for creating camera clock, but most other codes, use channel 0 and timer 0. i chose 1 because of things like this. everything and everyone by default use channel 0, and then everything gets messy.
for your particular problem, you have to use i2c channel 1 and create a new driver for your i2c. DO NOT USE the camera i2c or pins. i hope i was clear about what is wrong this time. besides, i don't think you have a direct access to its code and you are creating your own driver on top of the camera driver and that destroys everything!
to help you understand the code better, i would direct you to bool prepCam() in mjpeg2sd.cpp file.
by the way, the camera driver is NOT open source in Arduino. it is a library and closed source. if you need that, you can go to espressif esp32-camera

I'll look into this.

I2C sharing was meant for ESP32, on the ESP32S3 you have spare pins so assign separate I2C pins so you dont have to share.

[s60sc]

issue #718 raised on esp camera library

[PeterHonor]

@s60sc @josef2600 : Yeah! I changed Edit Configs->Peripherals->I2C SDA pin if unshared from -1 to another pin and everything is OK now. Thanks for your help and support
