New Release 1.70.5

[cicciocb]

I also have S3 boards with camera, and it's not that I'm not interested in using Annex with them, it's just that I'd need functions that Annex will probably never support (like simultaneous detection of multiple objects).

I'm not even sure that what I have in mind will ever work with an ESP32.

I implemented the "face detection and recognition" features in the ESP32 camera some time ago (and they are still present in the documentation) but I removed them since they were just a demonstration of the capabilities of the camera and not a real-world use case. The ESP32-S3 should be better as it contains specific AI processor instructions that are supposed to improve performance on these particular applications. However, I do not think this will lead to significant improvements, particularly for your specific requirements. Probably Nvidia H/W cards are more appropriated.
You might want to look online to see if someone has developed a practical application using this camera and start from there.

In my case, I want to replicate the function of the IR camera inside the Wiimote.
It detects the the four brightest IR sources in it's view, and gives back their positions via I2C.

And I honestly have no idea how to do this, I've never done anything serious regarding computer vision.

Hi Francesco,

I tried some configurations with the classic ESP32-Cam now.
I can use Version 1.70.5 with that hardware if
- I deactivate the SD-Card at the config-page
AND
- I do not use GPIO12 for PWM servo control.

Earlier AnnexCam versions allowed to use GPIO12 - now the PWM at pin 12 stops the camera immediately.

I have an additional issue using OTA coming from 1.51 going to 1.70.5
The config page reports "connection refused", whereas the browser can download the file.
(But that could be a software issue as I'm not sure if the OTA version 1.9 was already delivered with Annex 1.5?)

Thanks Peter, I'll check that.
About the OTA yes, you must update at the version 1.9 (the old one was working only for local updates and not by WEB)

Is there any chance to do an update from 1.51 to 1.70.5 without a physical connection to the module ?
I have one which is really hard to reach (in winter time).

If I got it right, the OTA-server of the windows Annex-toolkit together with the bin-file in the OTA directory should do the job. And that additionally needs the (old) OTA-client installed in the Cam.

This worked very smooth ! Thank you, this saves me a lot of inconveniences

@cicciocb I just wanted to thank you again for the gui.textarea function.

I'm currently using it in a program that controls a power supply and an electronic load, to do some experiments with high current MOSFET circuits.

The program has several pages (for settings, presets, etc.), and for every page, I use textarea to show a popup help text, loaded from separate text files.
Works well so far.

I know I'm annoying, but would it be much work to add a scrolling function and/or some text formatting, e.g. rich text format?

Or even better, html using https://github.com/warmcat/libwebsockets
(I know, I'm dreaming)
