Embedded Artistry

Here's a pinned tweet thread containing helpful resources for embedded developers. 🧵📌

Developers can run into trouble when using volatile in read-modify-write situations, such as ++ or -- operators - these can introduce an unexpected race condition. I recommend using wrappers like "volatile_load" and "volatile_store" to embeddedartistry.com/blog/2019/03/1…

We love studying existing software in order to find new approaches and techniques. This AX5043 radio IC driver shows us how we can decouple a driver from a communication bus using a minimal set of abstractions - just one in this case! embeddedartistry.com/blog/2019/08/0…

Fight for the space and time to reflect.

Die photo of an ALU chip, the venerable TTL 74181. I reverse-engineered a 74181 chip a few years ago; the layout is different in this one. righto.com/2017/01/die-ph… Thanks to @TubeTimeUS for providing the chip.

Have you avoided TDD because you've heard that your tests will be brittle and cause more trouble than they are worth? In 1999/2000 we thought the same thing only to discover the brittle tests were our fault. blog.wingman-sw.com/preventing-bri…

Most chips are formed on a silicon wafer, but this RCA telecommunications chip is constructed from sapphire. It is a silicon-on-sapphire CMOS chip, with silicon circuits sitting on top of a thin sapphire substrate. 1/11

The 386 processor (1985) was pivotal for Intel, moving the x86 architecture to 32 bits and moving the design to CMOS. Everything in the processor is controlled by the clock. Some tricky circuitry on the chip (red) generates the clock; let's take a look inside the die... 1/11

🎁 As we head into the holiday season, discover how you can be prepared to manage issue and improve products post launch. Join our panel of #embedded engineers from @mbeddedartistry and @wntrblm to learn more! RSVP here: hubs.la/Q02bmTv-0 #productlaunch @theavalkyrie

We keep calling ourselves software engineers, but engineers elsewhere advance their industry by analyzing failures and building up tools to stop those and make them standard industry practice! But we'll just have the same 6 problems, on a regular spin cycle, for like 40 years.
