Hi.
I recommend that you carefully check the pinout of your board.
You’ll need to adjust all pin definitions.
Then, double-check that your board uses a OV2640 camera. Otherwise, it won’t be compatible with our code.

Regards,
Sara

Please note that there are two “RST” buttons. One on the motherboard and one on the cam board. When using the IO0 long press and short RST press methods above, be sure to use the RST button on the cam board. The RST button on the motherboard does NOT work.

Hi, awesome project, I was checking the esp32 also can use USB to capture video with lib libuvc, but is there a way we can use this USB webcam to take photos and storage it on the SD? even more, I would like to atach multiple USB webcams to take photos like Nishika 8000 Style photos but I’m lost with the USB multiple webcam part

Hi.
I didn’t test it with that board.

This does not work with seeed esp32s3 sense.

output is a loop printing this:

20:44:18.637 -> ESP-ROM:esp32s3-20210327
20:44:18.637 -> Build:Mar 27 2021
20:44:18.637 -> rst:0x3 (RTC_SW_SYS_RST),boot:0x28 (SPI_FAST_FLASH_BOOT)
20:44:18.637 -> Saved PC:0x40377234
20:44:18.637 -> SPIWP:0xee
20:44:18.637 -> mode:DIO, clock div:1
20:44:18.637 -> load:0x3fce3818,len:0x109c

Hi,.
This code only works with OV2640 cameras.

Hello, I am facing a problem while interfacing the camera with the custom board.
I am using the ov5640.
I am using the esp32-D0WD-V3 controller.
These are the camera pins
#define XCLK_GPIO_NUM 4
#define SIOD_GPIO_NUM 18
#define SIOC_GPIO_NUM 23
#define Y9_GPIO_NUM 36
#define Y8_GPIO_NUM 37
#define Y7_GPIO_NUM 38
#define Y6_GPIO_NUM 39
#define Y5_GPIO_NUM 35
#define Y4_GPIO_NUM 14
#define Y3_GPIO_NUM 13
#define Y2_GPIO_NUM 34
#define VSYNC_GPIO_NUM 5
#define HREF_GPIO_NUM 27
#define PCLK_GPIO_NUM 25
power down and the reset pin is connected to the io expander (uses I2C).

I’d like to tell you that my task is to take a picture and store it in the SD card.

is this camera compatible with this controller esp32-D0WD-V3?

Can power down and reset the pins be implemented through the io expander?
if this is possible to implement I cannot able to navigate the c file related to this.
