ArduinoZero-PMUX-report. Generate a user-readable report of the current state of the pins (what they're doing) on Arduino Zero and other SAMD21 based systems

3

Atmel_ATDF_parser. Python code that parses the XML from an Atmel .ATDF Device Description file, and allows you to find/print various information and relationships that are not present in the .h files.
