Chris and Elecia talk about their current adventures in conference talks, play dates, and skunks. Elecia’s talks are available on YouTube: Creating Chaos and Hard Faults : An introduction to hard fault handlings, stack overflows, and debugging hard bugs Introduction to Embedded Systems (O'Reilly Expert Webinar) : An introductions to… well, embedded systems These are both advertising for the 2nd edition of Elecia’s book, Making Embedded Systems: Design Patterns for Great Software . You can also find it on O’Reilly’s Learning System and probably read it with your 30 Day Trial ( here ). Chris got a handheld game console, the Playdate ( play.date ), and has been writing a game for it. There is an interesting looking MicroPython port for it . We also mentioned Tiny Tapeout Demoscene which sounds pretty neat. And KiCanvas where you can see KiCAD schematics without loading KiCAD. Our newsletter has been off but will be back to normal next week. The RSS feed is probably not fun to look at but Elecia’s Rebloginator shows some Python tools for parsing feeds. Neither the dog nor the skunk seem contrite. Transcript…

Kwabena Agyeman joined Chris and Elecia to talk about optimization, cameras, machine learning, and vision systems. Kwabena is the head of OpenMV ( openmv.io ), an open source and open hardware system that runs machine learning algorithms on vision data. It uses MicroPython as a development environment so getting started is easy. Their github repositories are under github.com/openmv . You can find some of the SIMD details we talked about on the show: 150% faster: openmv/src/omv/imlib/binary.c 1000% faster: openmv/src/omv/imlib/filter.c Double Pumping: openmv/src/omv/modules/py_tv.c Kwabena has been creating a spreadsheet of different algorithms in camera frames per second (FPS) for Arm processors: Performance Benchmarks - Google Sheets . As time moves on, it will grow. Note: this is a link on the OpenMV website under About. When M55 stuff hits the market expect 4-8x speed gains. The OpenMV YouTube channel is also a good place to get more information about the system (and vision algorithms). Kwabena spoke with us about (the beginnings of) OpenMV on Embedded 212: You Are in Seaworld . Transcript Elecia is giving a free talk for O'Reilly to advertise her Making Embedded Systems, 2nd Edition book. The talk will be an introduction to embedded systems, geared towards software engineers who are suddenly holding a device and want to program it. The talk is May 23, 2024 at 9:00 AM PDT. Sign up here . A video will be available afterward for folks who sign up.…
