ESP32-CAM upgrade CameraWebServer with flash on ESP32 Framework 2.0.4

[rodyeo]

Hi! I have been following this blog page link example for a few days now trying to get the generic Example of ESP32 CameraWebServer with Flash from ESP32 Framework 1.0.6 to be ported into current latest ESP32 Framework 2.0.4 to work but failed.

Blog page link example …

ESP32-CAM: upgrade CameraWebServer with flash feature – 2

I came to understand the ESP32 Framework 2.0.4 has changed a lot compare to the old Framework 1.0.6 and it will not work even though there is no compilation errors.

Attached are two sets of files I dedicated for this ESP32 CameraWebServer Flash Light project for your analysis and troubleshooting on ESP32 Framework 2.0.4 Board Manager Library under Arduino IDE version 1.8.19 software on Windows 10.

Please take note to use this latest bugs fix repo… from https://github.com/espressif/arduino-esp32/pull/6993

This is the old existing bugs not fix yet repo…

I have created a set of batch files to aid in flashing 20 pcs of of Ai-Thinker ESP32-CAM to work on ESP32 Framework 1.0.6 and 2.0.4 for the purposes of easy trouble free batch processing.

Hi Rodyeo,
I check the 2.0.4 version of CameraWebServer, and I put on working with these changes.
In the main CameraWebServer.ino I add these lines.

const int pwmfreq = 50000;     // 50K pwm frequency
const int pwmresolution = 9;   // duty cycle bit range
ledcSetup(config.ledc_channel, pwmfreq, pwmresolution);  // configure LED PWM channel
ledcAttachPin(4, config.ledc_channel);            // attach the GPIO pin to the channel

after the setting of camera_config_t config; structure

And in the file app_attpd.cpp after the include I add these lines:

//
// LED Illuminator
//
#define CONFIG_LED_ILLUMINATOR_ENABLED
#define CONFIG_LED_LEDC_PIN 4
#define CONFIG_LED_MAX_INTENSITY 255
//#define CONFIG_LED_LEDC_LOW_SPEED_MODE
// CONFIG_LED_LEDC_HIGH_SPEED_MODE is not set
#define CONFIG_LED_LEDC_TIMER LEDC_TIMER_0
#define CONFIG_LED_LEDC_CHANNEL LEDC_CHANNEL_0
// end of LED Illuminator

I have also attached the modified files.

Bye Renzo

I still get compilation error using your two files attached. I believe you are still using the older copy of 2.0.4 with bugs issue 6996 as highlighted a few weeks ago…

I believe you must used this fixed code version … https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer

Submitted a bug report to Espressif System version 2.0.4 with sample code at … Examples \ ESP32 \ Camera \ WebCamServer compile error … https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer

I copied the two files you gave and override the sample file I attached earlier in my previous post and this are the compilation error I got…

This errors looks similar to my previous bug report to Espressif github … Error Compiling… Arduino IDE version 1.8.19 … Board Manager … ESP32 Espressif System version 2.0.4 INSTALLED #6996 https://github.com/espressif/arduino-esp32/issues/6996

Hi! I used your inserted your code modification into my CameraWebServer204FlashFailed.zip version I send you earlier with no compilation errors cause I used the latest fix copy from the Espressif Developer … https://github.com/…/ESP32/examples/Camera/CameraWebServer

[rodyeo]

Here is the final compiled and uploaded result in the ESP32-CAM with no errors.

[rodyeo]

Yes! Great! Thanks alot! Your new code is working now with the LED Illuminator slider function. It will be nice to also have the Flash toggle switch On / OFF to as a flash light features too if possible similar to Framework version 1.0.6 style?

[rodyeo]

Hi! Renzo your work have help the ESP32 Community closed pending request …

Hello! Renzo,

Your creations also address in another long awaited thread months back…

https://github.com/espressif/arduino-esp32/issues/6790

A big thank you buddy 🙂

You are indeed the GOD of ESP32 programming guru!

[rodyeo]

Bonjour Renzo 😉

Finally I hope to see your version 3 of the ESP32 CameraWebServer Flash Light LED Illuminator works publish soon at your blog site … 🙂

Rodney

[rodyeo]

I shall wait for your add on Flash Light LED Illuminator Toggle Switch function 😉

[Renzo Mischianti]

Thanks to you for helping to find the solution.
Bye Renzo

[rodyeo]

I shall help you promote your great works to all my IoT group members globally 😉 Thank you again sir Renzo. I am so happy to have bump into your blog and your great dedication to Open SOurce Community projects. Bravo!

This is the said working source code “CameraWebServer204Flash.zip” with the LED Illuminator slider features which activated when Still Image Photo or Video Streaming Video is triggered.

[rodyeo]

I decide not to be over demand in request porting version 1.0.6 flash codes into this 2.0.4 LED illuminator source code in respect of the author Renzo creations, therefore this new LED illuminator intensity control slider features is much better than previous LED Flash toggle switch method at older source code implementation. Many thanks to Sir Renzo for all his hard work and effort. Bravo! … CeraWebServer204LEDilluminator.zip

[rodyeo]

I am totally satisfied with final results of the ESP32-CAM CameraWebServer LED Intensity illuminator control function. Thank you Sir Renzo.

[Renzo Mischianti]

Good work Rodyeo!
Bye Renzo

[rodyeo]

*** Note the default is set to 50K PWM frequency for the LED Flash Light to sync with certain country AC electric supply at 50Hz. I experiences horizontal running lines on the web ui video output screen. My country AC is 60Hz therefore my PWM frequency is supposed to be 60K instead. Correct me if I am wrong?

[Renzo Mischianti]

Hi,
I think the frequencies is only for the pin PWM and you can use 50K.
