Arduino compatibility can mean a lot of things to a lot of different people, so we’ll try to be as concrete and specific as possible. For the Open-V, Arduino development tools, and interoperating on a hardware level with existing Arduino shields.
ORCONF 2016 was held earlier this month in Bologna, Italy:
ORCONF is an open source digital design and embedded systems conference, covering areas of electronics from the transistor level up to Linux user space and beyond. Expect presentations and discussion on free and open source IP projects, implementations on FPGA and in silicon, verification, EDA tools, licensing and embedded software, to name a few.
An annotated mRISCV die imageI don’t know about you, but the idea of an Arduino-class microprocessor board which uses completely open silicon is a pretty attractive prospect to us. That’s exactly [onchipUIS]’s stated goal. They’re part of a research group at the Universidad Industrial de Santander and have designed and taped out a Cortex M0…
Not only have [onchipUIS] successfully bonded their chip, but they’ve done so using a chip on board process where the die is directly bonded to a PCB. They used OSHPark boards and described the process on Twitter.
