ESP8285 Infrared Board

Leave a comment

I've once again found a small board with an ESP on the fast Ali. This time, however, it's an ESP8285, which apparently only differs from the ESP8266 in its internal 1MB flash memory. This board costs just under 4 Euros, has no USB port, and must be programmed with applications using a programmer. On the other hand, it has an IR receiver and an IR transmitter and is quite small. The ports are not brought out via pins, but it seems quite possible to solder cables to the ESP board. You'll find the data as always in the following chapters.

ESP8266 RTOS SDK

Leave a comment

The RTOS SDK is Espressif's own programming environment for the ESP8266. Facts The Arduino SDK also encapsulates the functionalities of this SDK. Now one might ask why write specialised code for the ESP8266 by using the SDK directly. The answer is not entirely simple but here are a few arguments: The framework offers extended functionalities which...

SwitchLib

Leave a comment

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…
