I’m currently exploring AVR and SAMD controllers for educational and personal projects. Like many people I started with AVR via Arduino and then migrated to Studio 7 and MPLAB X IDE. Most recently I’ve been focusing on the ATTiny3216, the AVR128DBxx, and the SAMD21.
I’ve posted some of my projects to GitHub, which you can see at this link: https://github.com/microPaul
