Then I thought, surely there must be something for the Raspberry Pi here too. After a quick Google search, I found the Shinobi software, which had already been tested on the Raspberry Pi.

Many who have worked with the ESP32 Cam have thought about extending it with a PIR or other sensors. LiLyGo has released a series of cameras, including the current model with a PIR sensor and some other interesting additions.

Very small antenna connector, mostly used in combination with an adapter with RP-SMA socket
Continue reading "U.FL / IPEX Antennen Steckverbindung"For some ESP projects that work with SD cards, there is an adaptation of the standard Arduino SD library. The classes are usually called MySD and allow other pins to be specified for the SPI interface.

Neatly packaged in a silicone wristband, this is the smallest version of the ESP32 that I know of. The ESP itself does not have its own programmer. However, there is a kit that contains the wristband and a programmer. Once initialised, the wristband can be updated via OTA.
Continue reading "VORSCHAU – ESP 32 Armband – LilyGo-T-Wristband"With new developments, it's important to send some outputs via the serial port or another medium. Of course, these outputs can simply be deleted or documented. But at the latest when the implementation is extended, they will be needed again. There are different approaches, which I would like to briefly present here. Which variant is the right one...
Continue reading "Debug Ausgaben im Quellcode"I needed a library to poll multiple buttons. Since I had three buttons but needed at least 4 functions, I implemented a short/long press detection. Each button can therefore be pressed briefly or for a longer duration and, after release, will call a callback method accordingly. Apart from a loop through the buttons, this library should not…

The initial idea was to read the MJPeg stream from the ESP32 camera and display it on the TTGO screen. As I was having problems implementing the MJpeg protocol, I opted for a simplified version and am now reading snapshots from the camera. This has the advantage that whenever the...

Developed at Motorola in 1987, it implements a „standardised“ serial bus for communication with peripheral devices such as displays, sensors, etc.
