New Release 2.00.9

[cicciocb]

Hmm, the serial connection is missing with the more powerful power supply, but I'll try it today with an ESP32 without a camera.
I don't have the time right now, so thanks for that.

Obviously, I was referring to a USB hub with a stronger power supply, one that is externally powered.
I have one of these because most recent modules-especially those with LCDs-require a significant amount of power.

My typical setup at the moment is this one:

External (switching) regulators for 5V and 3.3V, with reverse voltage protection diodes.
The ESP32 module already contains internal diodes, so you can use either an external voltage, or USB to supply everything.
And as cicciob said, some displays need more power than the internal (linear) regulators can provide.
I also often add a varistor a the external supply input. Long supply lines have inductivity, that can cause overvoltage, and you never know how good or bad a mains power supply may behave.

Hello community,

my first attempts with Annex are based on Francesco's recently published of the smallest possible program version using with ESP32-Cam, which photos can be sent by email as well as saved on a SD- card.
Based on this and with the help of many example files here in the forum, thanks to PeterN too, I have tried to create a small program extension, let me call it “Photo Trap”.

This program version can be triggered either by an external signal via interrupt, or by internal timer0. My intention with this program is to be able to operate a variety of applications, such as
----- Recordings at fixed time intervals for time-lapse videos, whereby the time intervals can be specified in advance in the program
----- Photos triggered by external sensors such as radar, IR or even light barriers

I tested the sending of emails and the simultaneous storage of these photos on an SD card with the internal timer, whereby a transmission takes place every minute. I have noticed that sometimes photos are not completely saved on the SD card, the error rate is about 5%.

Maybe someone knows this problem and has a solution.

I have not yet published a program text in this forum and will attempt to do so next.

There is a good solution for that issue now by means of AnnexCam 2.00.93
