WiFi enabled Gate Controller Addon to US Automatic Gate Opener

Enabled watchdog interrupt on microchip SAM D21 using manually registers

Arduino library DAC control using a serial (USB) terminal

Library to read out unique serial number from SAM D21 MCU, e.g. Adafruit Feather M0

Flashing LED Matrix "Super Computer" display inspired by bigclivedotcom

Library to detect a multi reset, using EEPROM, DueFlashStorage, FlashStorage_SAMD, FlashStorage_STM32 or LittleFS/InternalFS. For AVR, Teensy, SAM DUE, SAMD21, SAMD51, STM32F/L/H/G/WB/MP1, nRF52, RP2040-based (Nano_RP2040_Connect, RASPBERRY_PI_PICO), Portenta_H7, etc. boards. Now using efficient FlashStorage_STM32 library and supporting new STM3…

An Arduino sketch for Arduino MKR WiFi 1010 boards to function as a USB keyboard emulator

Arduino gpio positive and negative edge counter for samd21 (Seeeduino Xiao, Trinket Mo, QT PY)

This arduino code for SAMD21 will record a gpio's high and low duration for multiple pulses.

This library enables you to use Hardware-based PWM channels on SAMD21/SAMD51-based boards to create and output PWM to pins. Using the same functions as other FastPWM libraries to enable you to port PWM code easily between platforms.

Make your SAMD21 Arduino functions faster.

SAMD21 add-on

Firmware for the ReWire pulse oximeter

Code to read out the register states of the Arduino MKR 1010 Wifi (SAMDG18a)

Example code using te wireless remote controller (SAMD21) to control the SparkFun RedBot (ATmega328P) via XBee.

A software defined pattern is given by serial input and then driven on a gpio pin. Fastest pattern has 2us intervals, but any interval may be specified.

Open source low power FANET wind sensor

This is a small modification of the Arduino Built-in Example "Use Multiple Serial Ports on the Arduino Mega". The UF2 file was compiled for the Adafruit SAMD21 QT PY, but the INO file should apply to many other MCUs.
