Adding support for elegoo ESP32-Wrover module (Smart Robot Car V4.0 with camera)

[webermich]

Hello,

I own an "ELEGOO Smart Robot Car V4.0 with camera" and tried to use this project to access the video stream from the camera module.

However I wasn't able to get the camera working, probably due to misconfiguration.

When using the supplied software from the provider, the camera works, but I am not all too happy with the video stream though.

Could you please give advice on how to create a proper configuration profile?

Error:
Failed to initialize camera. Error: 0x105. Frame size: VGA (640x480), frame rate: 200 ms, jpeg quality: 14

Serial output:
serialmonitor.txt

Using the following config:
esp32cam_elegoo_wrover.json

All infos regarding the original driver:

I have the "ESP32-WROVER module" with “ESP32 Dev Module” configuration.
There are extra settings to be done:
partition scheme: Huge APP (3MB no OTA...)
PSRAMM: enabled

From the code I got the following pins:

#define PWDN_GPIO_NUM    -1
#define RESET_GPIO_NUM   -1
#define XCLK_GPIO_NUM    21
#define SIOD_GPIO_NUM    26
#define SIOC_GPIO_NUM    27

#define Y9_GPIO_NUM      35
#define Y8_GPIO_NUM      34
#define Y7_GPIO_NUM      39
#define Y6_GPIO_NUM      36
#define Y5_GPIO_NUM      19
#define Y4_GPIO_NUM      18
#define Y3_GPIO_NUM       5
#define Y2_GPIO_NUM       4
#define VSYNC_GPIO_NUM   25
#define HREF_GPIO_NUM    23
#define PCLK_GPIO_NUM    22

can you not just use the wrover definition? esp32cam_freenove_wrover_kit

Otherwise take a look at the file pins in your repository and try to match this to an existing board... Very well possible it is already there...

Hi @rzeldent ,

what you suggest is exactly what I tried. I used the esp32cam_freenove_wrover_kit definition, cloned it and made the pin modifications (that I thought should work). You will see the result in the file I uploaded. esp32cam_elegoo_wrover.json

Nevertheless, it doesn't work and I was reaching out to get advice.
Maybe I have missed out something?
