Re: ESP32-CAM: Can someone explain how the camera frame buffer pointer works
Hi, I don't think it possible to access individual pixels when it is captured as a JPG as it is stored in this compressed format so it would need to be decoded first. You could capture the image as RGB or Greyscale directly and access the data rather than capture as JPG then convert if (not somethin...

Re: I'm getting constant brownouts powering ESP32-CAM
I would try a decent sized capacitor on the 5v feed to the esp32cam
When using wifi it generates large spikes of power draw and this is probably upsetting your step up converter
If you have an oscilloscope it is worth having a look at the 5v feed to the esp32cam to see what is happening

Re: esp32-cam drops streaming after a while
Hi, I find power supply is always the first thing to suspect if an esp32 starts doing anything unusual I have heard reports of the cameras getting very warm so maybe check it is not overheating I have a sketch (Arduino IDE) which streams live video which you might like to try to rule out if it is th...

Re: esp32-wifi
It is worth checking the power supply to it is good as I have known them to do all sorts of weird things if they are not happy with the power.

If the timing needs to be accurate you could look at using NTP over wifi to get the actual time or use a Real Time Clock (RTC) module.

Re: esp32-cam ai-thinker, antenna, ext.antenna, your experience
My experience of the esp32cam module is the onboard antenna doesn't seem to work very well. well, It works ok but if you try and put it in any type of case or even have anything near it then it will often result in very limited range or even stop working all together Other esp32 development boards I...

Re: How to remove ESP32 Board from Arduino IDE on a Linux (Mint) Computer
Hi, I believe you just need to delete the "packages/esp32/" folder Problem is I don't remember exactly where it is as I use the "portable" option myself I think it will be in your home folder in ".arduino" or ".config.arduino" BTW - You may like to try the portable option yourself as it then keeps a...

Re: ESP32-CAM Rebooting when face detection is activated
It doesn't sound like it is likely the problem in this case but always worth checking that the 5 volt supply to the camera is good. I have found that it needs a very good power supply and if it is not happy with it you can get all sorts of weird errors, behaviour, reboots etc.. I have often forgot t...
