USB Mass Storage bootloader (based on UF2) for SAMD21 and SAMD51

This is simple yet complete WebServer library for AVR, Portenta_H7, Teensy, SAM DUE, SAMD21/SAMD51, nRF52, STM32, RP2040-based, etc. boards running Ethernet shields. The functions are similar and compatible to ESP8266/ESP32 WebServer libraries to make life much easier to port sketches from ESP8266/ESP32. Coexisting now with `ESP32 WebServer` and `ESP8266 ESP8266WebServer` libraries. Ethernet_Generic library is used as default for W5x00.

Minimalist portable USB device stack for SAMD21, LPC1800, LPC4300, Xmega

⚡️Arduino E-Mail Client Library to send, read and get incoming mail notification for ESP32, ESP8266 and SAMD21 devices. The library also supported other Arduino devices using Clients interfaces e.g. WiFiClient, EthernetClient, and GSMClient.

LMIC-node | One example to rule them all. LMIC-node is an example LoRaWAN application for a node that can be used with The Things Network. It demonstrates how to send uplink messages, how to receive downlink messages, how to implement a downlink command and it provides useful status information. With LMIC-node it is easy to get a working node quickly up and running. LMIC-node supports many popular (LoRa) development boards out of the box. It uses the Arduino framework, the LMIC LoRaWAN library and PlatformIO.

This library gives an example of how to get FreeRTOS running on Seeed production. The project can be used as a template to build your projects off of as well.

Functions for many of the ADC capabilities of the ATSAMD21 series.

TinyDraw is a package of drawing primitives on TinyGo displays.

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 need to measure some data requiring better accuracy. It now supports 16 ISR-based Timers, while consuming only 1 Hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based Timers. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks.

Simple way to control your IOT development boards like ESP8226, ESP32, Arduino SAMD21, Adafruit SAMD21, SAMD51, nRF52, STM32, Teensy, SAM DUE with Amazon Alexa or Google Home
