[jjsch-dev]

thanks for the information, I made a fork of the esp32-camera and the pull request for adding the ov7670 driver. Please tell me if you can get the changes.

[jjsch-dev]

The esp32-camera-master is part of the idf component, you need to copy it to the folder idf/componnets. I use a fork of the igrr/esp32-cam-demo, if you need it please let me know.

[jjsch-dev]

ok, I will made the fork tomorrow.

[jjsch-dev]

I made the pull request to the igrr/esp32-cam-demo. Please use this project and compile.

[jjsch-dev]

Checking the rep for the es32-camera, by mistake I forgot to add the drivers files:
sensors/ov7670.c
sensors/private_include/ov7670.h
sensors/private_include/ov7670_regs.h
please check now.

[jjsch-dev]

Now I merge the igrr/esp32-cam-demo in my repository. Please use this project and compile.

[jjsch-dev]

The esp32_camera driver need to be inside the components folder of esp-idf, please check if you have a similar list.

[jjsch-dev]

ok, please try to move the folder esp32-camera to the folder esp-idf/components.

[jjsch-dev]

you need to obtain two source code, one is the esp32-cam-demo-master (the application), please leave it in the example folder, but the driver code esp32-camera need to be in the folder esp-idf/components.

[jjsch-dev]

the camera driver: https://github.com/jjsch-dev/esp32-camera
the camera demo: https://github.com/jjsch-dev/esp32-cam-demo

[jjsch-dev]

please copy all files.

[amirjak]

Thank you for your work .
It works .

I have a problem with the color of the photo ?

But it didn't work

[jjsch-dev]

The file is the sdkconfig, but you can change the configuration using the utility menuconfig. Some times you will need to clean project to update the configuration, use: make clean.

Launch the menuconfig

Change the clock frequency

Enable test pattern

[amirjak]

I think I missed something

So I deleted everything and started from the beginning

I have downloaded these files again

And put them in these folders

---

jjsch-dev/esp32-camera

esp\esp-idf\components\esp32-camera

---

jjsch-dev/esp32-cam-demo

esp\esp-idf\examples\esp32-cam-demo

---

igrr/esp32-http-server

esp\esp-idf\examples\esp32-cam-demo\components\http_server

---

And then at mingw32.exe

And then it happened

It does not work

[jjsch-dev]

I reproduce the problem by increasing the frequency of the camera clock by 120 Mhz, please use 12 Mhz.

[amirjak]

frequency 12000000 not working

[jjsch-dev]

I do some test with my board, and found the camera clock limit is 24 Mhz, but work fine from 12 to 20 Mhz, and present the problems that you first reported with 10 Mhz. All test was made it with 240 Mhz for the cpu clock.

Camera clock = 10 Mhz

Camera clock = 15 Mhz

Camera clock = 20 Mhz

Camera clock = 24 Mhz

CPU clock = 240 Mhz

[amirjak]

After the camera color had a problem

I deleted the msys32 program with its folder

After that, when I reinstalled the program, I had a this problem

I made these changes

And then it happened

If you can send your cpu_start.c file to me

[jjsch-dev]

ok
cpu_start.zip

[jjsch-dev]

It is possible that you use are using a newer version of module ledc than me. I found in the esp32_camera a similar report:
LEDc configuration error and camera_probe failed #66 of https://github.com/masterd89

https://github.com/mirronelli suggest add the following sentence to fix the problem.

there was a change in ledc driver that is used to drive the clock

to work with the current version a one line of code needs to be added into xclk.c
the line is:

timer_conf.clk_cfg = LEDC_USE_APB_CLK;
put in in the block bellow

    ledc_timer_config_t timer_conf;
    timer_conf.duty_resolution = 2;
    timer_conf.freq_hz = config->xclk_freq_hz;

timer_conf.speed_mode = LEDC_HIGH_SPEED_MODE;
timer_conf.timer_num = config->ledc_timer;
timer_conf.clk_cfg = LEDC_USE_APB_CLK;
esp_err_t err = ledc_timer_config(&timer_conf);
if (err != ESP_OK) {
ESP_LOGE(TAG, "ledc_timer_config failed, rc=%x", err);
return err;
}
you will find the the file in yourproject/components/esp32-camera/driver/xclk.c

use of the APB clock was assumed in previous commit to ledc.c and now it needs to be explicitly set

[amirjak]

Thank you for your work .

It works .

[jjsch-dev]

Glad to hear that!

[billyrudi]

Hi, how i can use camera with arduino ide?
i have esp32-cam board and ov7670 camera module.
regards Paolo

[amirjak]

https://github.com/amirjak/how-made-night-vision-camera-with-esp32

[jjsch-dev]

you need both, xclk is the sensor input, and pclk is the reference output for capturing from esp32.

[ecallens]

Hi,

Thank you for the driver and the demo code. It works fine using the standard ESP32-WROVER-KIT Camera Pinout. I tried using it on the Wrover kit V3 with a custom pinout for a project and I have a color issue.

Here is my menuconfig relevant configuration :

Any idea why I could have this color problem with this specific pinout on the Wrover kit v3 ?
Thanks

[jjsch-dev]

Hi @TheEdwood , I'm glad that you were able to make the camera work, regarding the problem, verify that the camera clock is higher than 10 Mhz. CONFIG_XCLK_FREQ = 12000000

[ecallens]

HI @jjsch-dev, The frequency is already set to 12000000 as you said, I checked on the sdkconfig.h generated file. I also have the problem with 20 MHz clock

What I find weird is that I have this problem only with this specific pinout (as showed in the pictures above). Is there any pin that can't be used with the camera interface ?

Thanks

[ecallens]

Hi @jjsch-dev,

I found the issue.
I was using the IO32 and IO33 pins for D3 et D2 signals. In the ESP32-WROVER KIT V3, these pins are used for a 33 kHz crystal peripheral, and are therefore not wired to the main connector. A resistor combination can be changed to switch the configuration and use the pins.

From the espressif kit description page (https://docs.espressif.com/projects/esp-idf/en/latest/esp32/hw-reference/esp32/get-started-wrover-kit-v3.html) :

"Since GPIO32 and GPIO33 are connected to the oscillator by default, they are not connected to the JP1 I/O connector to maintain signal integrity. This allocation may be changed from the oscillator to JP1 by desoldering the zero-ohm resistors from positions R11 / R23 and re-soldering them to positions R12 / R24."

With this taken care of, the camera works.
Thanks !

[jjsch-dev]

@TheEdwood I'm glad you found the problem.

[Rajssss]

@jjsch-dev I am getting these two errors:
connect.c: undefined reference to start' connect.c: undefined reference to stop'
Any idea?
I am trying to build your example esp32-camera-demo.
I see void start(void) and void stop(void) is declared in connect.c but they are not defined?

[jjsch-dev]

@Rajssss I can't find references to stop or start in app_main.c. Could you tell me which line of the code they are in?

[Rajssss]

@jjsch-dev its in connect.c, actually its part of protocol_examples_common example.
Line 50 and 53 has the deceleration and line 87 has a call to start().
I have another question is that demo (https://github.com/jjsch-dev/esp32-cam-demo) really meant to be work with your driver?

[jjsch-dev]

@Rajssss Sorry for the delay in responding, I checked the repository and I saw that there are changes in the camera driver, so I'm not sure that the demo application works with the latest version.
This weekend I will try to compile the camera demo with the new driver version.

[Rajssss]

@jjsch-dev thanks :) It will be fine for me if you can share the same version (If you have it still now) which was working earlier for you.

[jjsch-dev]

esp3_camera-jjsch-dev

[Rajssss]

@jjsch-dev thanks again. but that link point to same driver right? I am not sure what you wanted to point out here.

[kshitijgarg2609]

I have found this pins_camera.h in the examples given in esp32 arduino, I try to use these pin sets with OV7670 by defining Wrover kit

I also tried to change frequency from 20mhz to 12mhz. but the camera is never detected. As mentioned in library that it will support OV7670, so is there anyway to interface this ov7670 fifo camera with esp32 and using esp_camera.h?

[jjsch-dev]

@kshitijgarg2609 Hi, I have not tested the controller on arduino, could you please pass me the imo file you are using so that I can perform tests?

[kshitijgarg2609]

@jjsch-dev ,I am sharing the codes here, Please check.

@kshitijgarg2609 , Thanks for the code, I'll check it out in the next few days.

[kshitijgarg2609]

@jjsch-dev tested?

[jjsch-dev]

@kshitijgarg2609 sorry for the delay in responding, these days I was busy, today I started to test the example you gave me on Arduino, I keep in touch.

[jjsch-dev]

@kshitijgarg2609 Hello, the code you sent me is fine, the problem, (if the pins are configured correctly), in my case was that the OV7670 does not support JPG as a format, and if you do not have PSRAM the size of the frame has to be QQVGA.

I modified the code a bit (attached to the 3 files in zip format), so that at first it reports the PID of the detected camera, for the OV7670 it is 0x76.

esp32_cam_test.zip

[kshitijgarg2609]

@jjsch-dev Thank you very much for considering such issues. I have downloaded the code and tested it again, please can you share the circuit diagram or please tell me which other components like resistance to be used. Unfortunately, I am getting frame error again.

[jjsch-dev]

@kshitijgarg2609 Hello, my circuit diagram with an OV7670 sensor and an ESP-32 MCU node is as follows. Can you share the initialization that Arduino sends through the serial monitor?

I tryed the ov7670 example with the current librarys, followed the pin connections, but not working:/

This example will be important, because i want use with a parallel 8 bit display for my door-eye project, to get better speed, but there is no working driver or example.
