The ESP32 is capable to activate the energy saving modes of light sleep and deep sleep, but in many cases we cannot use such a solution, but it is still possible to apply some options to the functional units for reducing energy consumption.
Let’s set the sleep mode, disable the WiFi and scale the frequency to the CPU.
Modern web application need realtime update, for year we use polling system with REST call but now we can’t ignore WebSocket.
Here a complete reference implementation of a web application with token authentication.
Modern web application need realtime update, for year we use polling system with REST call but now we can’t ignore WebSocket.
Here a WebSocket server with esp8266, esp32 with some method to enable authentication.
Modern web applications need to update data in real time, for years we have used polling with REST calls but now we can no longer ignore the WebSocket protocol.
Here I am going to present a WebSocket client with esp8266, esp32 and Arduino Mega with enc28j60.Here a WebSocket client with esp8266, esp32 and Arduino Mega and enc28j60.
In the past 2019 new ESP32 board was born, the s2 family. At first only the ESP-IDF platform was supported, but now the version for the Arduino ecosystem is also quite mature, although the official version for the Arduino IDE has not yet been released.
Here a little tutorial to learn how to manage a complete web server via esp8266 esp32 or other arduino like device.
When we speak about web server we know that the basic is serving a web page, in a micro-controller we have some solution to do that.
Here a little tutorial to learn how to manage a complete web server via esp8266 esp32 or other arduino like device.
Now we are going to learn the basics, and a simple sketch to manage builtin led.
Serial Peripheral Interface Flash File System, or SPIFFS for short. It’s a light-weight file system for microcontrollers with an SPI flash chip. The on-board flash chip of the ESP32 has plenty of space for your files.
ESP32, a little guide on how to use this low cost but powerful microcontroller with WIFI integrated.
Pinout, specification and IDE configuration to start use your esp32.
FlatCAM is a program for preparing CNC jobs for making PCBs on a CNC router. Among other things, it can take a Gerber file generated by your favorite PCB CAD program, and create G-Code for Isolation routing.
Here we are going to create gcode and show the milling process.
