ESP32: manage multiple Serial and logging for debugging – 3
ESP32 have 2 multiple UART, they are very usefully for debug, and this device have also a core logging system that you can use to debug and control your code.
ABB Aurora PV inverter library for Arduino, esp8266 and esp32
Here my library that implements the complete communication protocol of ABB (ex PowerOne) Aurora Inverter suitable with Arduino, esp8266 and esp32.
Network Time Protocol (NTP), Timezone and Daylight saving time (DST) with esp8266, esp32 or Arduino
When you create a device you probably need to know the correct time, on wifi device the resonably choiche is to use Internet to get time via NTP.

Send emails with attachments (EMailSender v2.x library): esp32 and esp8266 – 2
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.
ESP32: integrated SPIFFS FileSystem – Part 2
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.
