The board circuit design and schematic are done. This is pretty terrible picture export. I couldn’t figure out how (spent 15 seconds) to export an SVG of the board without the copper fills. And here is the 3D rendering. A lot of 3D representations of components are missing, but the general gist is conveyed. All of the design work was done using KiCad (http://kicad-pcb.org/) EDA. Which of course means that I had to learn KiCad. Read more…

Finally real progress is being made. The I2C communication stuff is working on both chips. I’m taking the register-based approach and have tested the implementation of all of the basic registers. Did a bit of stress testing on the communications stuff – weird input, input overflowing buffer sizes, collisions, and etc. and everything seems to be working fairly well in a sense that there’s no corruption, the failures are predictable and graceful, all data gets Read more…
