YAML <=> JSON converter for ESP32, ESP8266, RP2040 and possibly other devices

This library enables you to use Interrupt from Hardware Timers on supported Arduino boards such as AVR, ESP8266, ESP32, SAMD, SAM DUE, nRF52, Teensy, etc. These Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other softw…

The FlashStorage_STM32 library aims to provide a convenient way to store and retrieve user's data using the non-volatile flash memory of STM32F/L/H/G/WB/MP1. It's using the buffered read and write to minimize the access to Flash. It now supports writing and reading the whole object, not just byte-and-byte. New STM32 core v2.0.0 is also supported…

mDNS Library for nRF52, SAMD21, SAMD51, SAM DUE, STM32F/L/H/G/WB/MP1, AVR Mega, RP2040-based boards, etc. using Ethernet W5x00. Supports mDNS (Registering Services) and DNS-SD (Service Discovery). Ethernet_Generic library is used as default for W5x00

This library enables you to use Interrupt from Hardware Timers on an SAMD-based board. These SAMD Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using millis() or micros(). That's mandatory if you …
