esp32cam-demo's Issues

the output of RGB888 data

Hi, thank you for your codes and explanation. It really helps for me to understand how to control ESP32-CAM.
Currently, I want to get raw data of 240*320 or little higher resolution images(preventing psram issue) for image processing.
So I tested with your code to get RGB888 data and sucess to get the rgb file.
But,

1. I couldn't open the file because it looks like broken. Could you give me idea to handle this file?
2. Is there any method to get the real raw data file from camera sensor(OV2640) with ESP32-CAM?
   Thank you in advance for your help.

Error: failed to capture image

When I try to capture a jpeg or a stream, I get this error message Error: failed to capture image

I'm using an AI-Thinker board (the chip has the Espressif logo); Arduino 1.8.19 with ESP32 core 2.0.13

I tried with another OV2640 lens with the same result. If I removed the lens, I can runs the example sketches in Arduino, like WifiScan, Test LittleFS, Deepsleep, GpioInterrupt, etc.

License of the project

Hi, I would like to use your code as a start for my (open-source) project. Am I allowed to use the code and publish a modified version? I'm asking because I couldn't find any license information on the project page. Maybe you could add a MIT License or something comparable?

Thanks for answering,
Leon

Where is the function fmt2rgb888 located?

I want to capture the jpeg data and convert it to rgb. Then I will process the rgb data inside the esp32 without sending the data anywhere. So it appears that all I need to do is run the function fmt2rgb888. How do I include that function in my code?

steam in QVGA and record in VGA

Hi,

Is it possible to stream and record using different resolution? I want to save a high resolution video and stream at the same time but due to wifi latency, I cannot stream on high fps(more than 10). I figured if I could stream using QVGA resolution I will achieve that framerate. Any key pointers would be appreciated.

General question

Hallo,
I have the following "problem" when I take a picture, the save picture is not the newest one. It is the picture taken before. So it is every time 1 picture behind.
Is this a general problem?

Add ability for AM312 motion sensor on pin 13

Reading through the config it says pin 13 is free.
Can you add the ability for a motion sensor to trigger a picture via that pin?

Dataline SDCARD and FlashLED

Hallo,
the Data1 Line is directly connected to the mosfet driving the FlashLED, if I use SDCARD the FlashLED ist turned on a little bit. I must cut the trace and connect to another IO for the LED ?

i saw your post about gpio 33 pin of esp32 cam here i want reply but issue was closed so here i am replying.

here is your problem link that you post
https://forum.arduino.cc/t/is-there-an-adc-gpio-i-can-use-on-the-esp32-cam-to-read-and-ldr/691720
i just try that because i need adc pin for sending voice with with video so i got successfull result i just cut the led out and connect adc pin of max9814 and it work fine as the built-in red LED on the ESP32-CAM and connect GPIO33 to an external component such as an ADC (Analog-to-Digital Converter), you can repurpose the pin as an ADC input. The ESP32-CAM has a 12-bit SAR ADC.

Which file to upload for OTA?

Using

• Sketch > Export Compiled Binary, and
• Sketch > Show Sketch Folder

in v2.3.2 of the Arduino IDE, I created all these files in build/esp32.esp32.esp32cam/:

• esp32cam-demo.ino.bin
• esp32cam-demo.ino.bootloader.bin
• esp32cam-demo.ino.elf
• esp32cam-demo.ino.map
• esp32cam-demo.ino.partitions.bin

I have #define ENABLE_OTA 1 in my wifiSettings.h, and a const String OTAPassword; login works. Which, if any, of the above files do I upload on the Update firmware page?
