Re: Two ESP32-CAM synchronously streaming to PI4

Hi Lucas, As far as I can understand, you want to collect all frames in the loop and give the latest to the web server. Am I correct? I will continue based on that assumption :) You should not use busy loops inside threads, instead you should use one of the FreeRTOS objects that allow for threads to...

Re: ESP32-CAM Stop Working

please try to diagnose the problem a bit more. Just stop working does not give any clues :) I have ESP32 cams running for days without issues. What is the XCLK that you are using? What is in the logs when they stop? Which example are you running?

Re: ESP-EYE __ Camera init failed with error 0x20003

Can you swap the sensor on that board and try again? Put one from the other working cams and see if it's the board or the sensor that is faulty (I will bet on the sensor here). Error means that the ESP was not able to communicate over I2C with the camera, but the line before that means that the came...

Re: ESP32 CAM direct access to image data

I don't agree that things are not well documented. The camera driver is rather a basic thing. You setup the camera and start grabbing frame buffers from it. Structure of the frame buffer is in the header. Frame buffer in every case that I have seen contains an array of pixels in the form of (width *...

Re: ESP32 CAM direct access to image data

I'm really sorry you find this so frustrating. I had no idea that "GRAYSCALE", "RGB565" or any other of the formats need explanation. 1. GRAYSCALE means values from 0 to 255 for each pixel 2. RGB565 means that a 16 bit value is per pixel and is comprised from 5 bits red, 6 bits green and 5 bits blue...

Re: SPI slave mode, CLK cannot be on input only pin (see GitHub issue #2455)

I'll try to update the IDF libs over the weekend. That should fix the issue :)

Re: ESP32 development board with OV2640 Camera

Hey! :) You can search online for waveshare ov2640 and you will find a module with the camera and two row header. This will let you easily connect the camera to your board, but please be noted that your board does not have PSRAM and this will limit much what you can do with the camera. I advise you ...

Re: Meshkit-light video example explanation wanted

While iOS will be definitely fully supported (Desktop also), as of now they are not so much. If you can have an Android emulator be able to access your BT in the Mac, then you could probably try that.the bulb and it's board are capsulated and filled with some sort of technical cement, so you do not ...

Re: Meshkit-light video example explanation wanted

Sorry, I personally have no idea about possible channels to obtain the bulbs, but I am pretty sure that Mouser has them also. You flash the bulbs through the Android App, which does it in the OTA fashion, so no pins are required :) Arduino is not yet supporting the full MDF. Once all heavy developme...
