issue 101 - Embedded systems newsletter

Embedded systems #101

Newsletters 101: Publish regularly and try as much as possible to keep the quality high.

Without transition, I would like to share that I’m working to add a new section to the website. A section to let engineers share on one page 2/3 pictures of their lab/desk and a few words on themselves. If you are interested to share your workspace, send me an email, and I’ll let you know what to do.

Thank you to Frank Wang for the header’s picture.

Happy reading!

Building a system based on the W65C816S microprocessor
An excellent series of posts describing component by component how the author creates them. There are posts on the PCB design, a VGA extension card, a sound card or the creation of an emulator. The author is still building the system so we can expect future posts.

Linux Inside
Very good writing covering the Linux kernel implementation details.

Driving a Large E-Paper Display with a Compact Xiao RP2040
This small project is interesting specifically because of the large aspect of the e-paper display. Nothing more, nothing less.

FabGL is a huge one man work. Fabrizio built an impressive set of libraries for ESP32. The biggest part is display driver but FabGL comes with few others components: keyboard and mouse control, audio engine, game engine, etc…
