Electronic, 3D printing and embedded programming
Microservices architecture is very popular for various reason, and It’s quite simple to implement with our microcontroller like esp32 or esp8266. The CORS request tunnel, OPTION and GET verbs.
I would like to monitor the status of my ABB Aurora inverter (formerly Power One now Fimer). So with a WeMos D1 mini I create a monitoring station with web interface, notifications and more.
Here we will explore the infrastructure of the project.
Microservices architecture is very popular for various reason, and It’s quite simple to implement with our microcontroller like esp32 or esp8266. POST, PUT, PATCH, DELETE.
LittleFS is recently added and focuses on higher performance and directory support, but has higher filesystem and per-file overhead.
Today for esp8266 and esp32.
Here I’d like to explain the version 2 of the EMailSender library, a big evolution respect to version 1, with support for Arduino with w5100, w5200 and w5500 ethernet shield and enc28J60 clone devices, and support for esp32 and esp8266.
Now you can add attachments also, loaded from storage device like SD, SPIFFS or LittleFS per esp8266.
Microservices architecture is very popular for various reason, and It’s quite simple to implement with our microcontroller like esp32 or esp8266. GET and JSON formatter.
Microservices architecture is very popular for various reason, and It’s quite simple to implement with our microcontroller like esp32 or esp8266. Startup.
RS-485 work as a broadcast; when you send a message, all devices connected to the wire receive that, so peoples use It is better to implement a lot of protocol to send a message to a specified device or a broadcast address. This article uses regular communication from two devices in a very simple way.
Library to use i2c pcf8574 IC with arduino, esp8266 and esp32.
This IC can control (until 8) digital devices like button or led with 2 only pins.
Here I explain the manage of multiple rotary encoder.
For static information (Web pages for examples), that not change frequently, esp8266 or esp32 have internal SPIFFS (SPI Flash File System) and you can upload data via Arduino IDE as explained in the article “WeMos D1 mini (esp8266), integrated SPIFFS Filesystem” but for fast operation and future support It’s usefully use FTP.
