Electronic, 3D printing and embedded programming
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.

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.

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.
