Esp8266 specification divides into three parts: Hardware, Software, and Wi-Fi. In hardware specification, its package size is QFN 32pins with a dimension of 5mm x 5mm. Operating voltages range from 2.5V to 3.6V. The chip consumes 80mA of current on average. Its CPU is Tensilica L106 whi...
This instructiable builds onUsing ESP8266 GPIO0/GPIO2/GPIO15 pinsto show you how you can get four (4) usable inputs/outputs for you next ESP8266-01 project and how to use IC2 to get even more inputs. It also covers how to drive the on-board Blue Led and has links to how to ...
The ESP8266 has by far not enough RAM to hold this amount of information in the RAM. That’s why we used an old trick known from the first home computers to reduce the color information per pixel. Instead of 16bit “True Color” we use a palette of defined colors. Before the library...
This tutorial focuses on the pinout of the ESP32 development board, specifically the ESP32 devkit that incorporates the ESP-WROOM-32 module. While various versions of the ESP32 chip exist in the market, the ESP32 devkit utilizes the ESP-WROOM-32 module. Fortunately, the functionality of all ...
To make use of the Arduino IoT Cloud, there is a need to have a board that is cloud compatible. Also, you will choose between making use of the official Arduino board, as well as a board that is based on the ESP8266 / ESP32 microcontroller. This Arduino IoT Cloud presently supports ...
I am working on Esp32c6 module and the tool is Espressif ide(V 5.1.2). In my application ESP32C6 configured as a SPI slave and stm32 configured as a SPI master. My application is to receive the data from master(stm32) through spi protocol and send the received data to Wi-Fi throug...

[Simon] also makes extensive use of the Chrome developers tools when building the HTML for the ESP. This is a handy trick even outside of ESP8266 development which might be useful for other tasks as well. Even though most of the guide won’t be new to anyone with experience with these...

A disk volume called RPI-RP2 should pop up on your desktop. Double-click to open it, and then drag and drop the UF2 file into it. Your Pico is now running a webserver. Unfortunately it’s not going to be much use until we wire it up to our Ethernet breakout board. ...
