Justin Mattair's repositories
ArduinoCore-samd
This is a fork from arduino/ArduinoCore-samd on GitHub. This will be used to maintain Arduino support for SAM D|L|C (M0+ and M4F) boards including the MattairTech Xeno Mini and the MT-D21E (see https://www.mattairtech.com/). It adds support for new devices like the D51, L21, C21, and D11. It also adds new clock sources, like a high speed crystal or internal oscillator.
SAMD-MSD-Bootloader
USB MSD (Mass Storage Device) bootloader for Atmel SAMD chips
ArduinoCore-avr
Fork of the Arduino AVR Core to support MattairTech AVR development boards
BOSSA
BOSSA is a flash programming utility for Atmel's SAM family of flash-based ARM microcontrollers. The motivation behind BOSSA is to create a simple, easy-to-use, open source utility to replace Atmel's SAM-BA software. BOSSA is an acronym for Basic Open Source SAM-BA Application to reflect that goal.
EEPROM_CAT25
Driver for On Semiconductor CAT25 SPI EEPROM chips for AVR, SAM3X (Due), and SAM M0+ (SAMD, SAML, SAMC) microcontrollers on the Arduino platform.
CMSIS-Atmel
Register definitions for the SAMD21, SAMD11, SAML21, and SAMC21 (vendor portion of CMSIS)
