Electronic, 3D printing and embedded programming
I have been prototyping PCBs with the CNC for years. I have created a CNC machine suitable for this, and today I would not know how to do it without it.
I have been using bCNC for some time as a GCode sender, a very simple open-source software, we will see how to install it and do the probe.
The ESP32 has enough resources to be able to use a FAT system which is certainly more expensive in terms of resources, but which offers large dimensions and few limitations, as well as compatibility with various devices.
LittleFS was recently added and focuses on higher performance and directory support, but has a higher resource consumption and occupancy per file, although not by default for esp32 it should be remembered that it takes up less resources than FatFS.
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.
