Part 51: Electronic Instrument Cluster Conversion – Part 5 – My 76 Mazda RX-5 Cosmo Restoration

Point is, this video clip consists of the whole of last setting up of the electronic tool cluster and it was an experience. Things damaged, mistakes were made, more things broke, and also add a lengthy wait for replacement parts.And after that I had the joy of experiencing it all while editing and enhancing this monstrosity. Here’s the thing: it worked out instead well as well as also though I have months of programs to make this cluster really do anything even more than puddle the needles, I believe it was worth it.

Part 51: Electronic Instrument Cluster Conversion – Part 5 – My 76 Mazda RX-5 Cosmo Restoration

Episode 51 of my ’76 Mazda Cosmo restoration is here! First, let’s talk length. That’s what she said. I know it’s ridiculously long. The title of my sex tape. Thing is, this video contains the entirety of final assembly of the electronic instrument cluster and it was an ordeal. Stuff broke, mistakes were made, more stuff broke, and add a long wait for replacement parts.And then I had the joy of reliving it all while editing this monstrosity. I could have split it into two, but then that would extend the instrument cluster to 6 parts and I just wouldn’t have it. So dear viewer, I implore you to have the same experience watching it as I had making it. But here’s the thing: it worked out rather well and even though I have months of programming to make this cluster actually do anything more than twiddle the needles, I think it was worth it.

EYE ON NPI – Digi-Key Electronics Innovation Handbook #EYEonNPI #DigiKey @DigiKey @Adafruit

Today’s EYE ON NPI is hittin’ guides – we’re including the Digi-Key Electronics Innovation Handbook (https://www.digikey.com/en/resources/innovation-handbook) today – which was just launched so it’s fresh as well as extremely brand-new. We just got ours in the mail!

The Digi-Key Innovation Handbook is your guide to maintaining some of the most highly referenced content from Digi-Key at your fingertips while giving you a lot of space to maintain your thoughts, tasks, and concepts handy. We highlight concepts, formulas, elements and also digital staples so you can describe them at any moment. From reference tables and also schematic symbols to resistors with Raspberry Pi’s the Innovation Handbook is the top place to try to find all your job needs. It likewise consists of over 120 grid-lined note pages for you to make use of any method you please. Obviously, we could not fit it all in guide so listed below you will certainly locate added details to go much more extensive right into each of the topics consisted of in the printed edition.

The Innovation Notebook has some overlapping details, yet is a lot more up to day. There’s likewise a lot of referral components – so if you simply need “a servo” or “an SMD red LED” there’s component numbers prepared to go for you to reference. I’m a big fan of that since there’s most definitely the most popular of each part, as well as for lots of manufacturers as well as beginners, they must just obtain that part rather than spending a whole lot of time in the Digi-Key search system.

In the front, there’s 40 web pages of layouts and also references, and after that there’s 120 gridded web pages, so it’s absolutely designed to be a scientific/design notebook, not simply a technical referral. Right currently it’s V1.0 of the publication, and also there’s possibly a great deal more stuff that they can include or boost. Please do not hesitate to send out comments, ideas and also future recommendations to support@maker.io to aid see to it the next version is also much better.

This note pad creates an excellent gift for any kind of pupil or manufacturer, as well as at a fantastic price. If you’ve obtained a cart going at Digi-Key, you can add one of these in – there’s hundreds of Innovation Notebooks in stock now (https://www.digikey.com/short/mf58fmj8) and also at least books aren’t affected by the part scarcity! If you want to look into the PDFs or other design resources, browse through https://www.digikey.com/en/resources/innovation-handbook for online tools, calculators, printouts as well as even more.

Introduction to RTOS Part 12 – Multicore Systems | Digi-Key Electronics

Running jobs in an RTOS on a multicore system can appear intimidating at. When writing programs that use even more than one core, many cpus have special architectures that you must keep in mind. We analyze the FreeRTOS port for the ESP32 (referred to as ESP-IDF) and just how to synchronize tasks on both cores.

The option to the challenge can be located right here: https://www.digikey.com/en/maker/projects/introduction-to-rtos-solution-to-part-12-multicore-systems/369936f5671d4207a2c954c0637e7d50

Code for this video clip collection (consisting of demos, services, and difficulties) can be discovered below: https://github.com/ShawnHymel/introduction-to-rtos

Configuring a multicore system can be divided right into 2 standards: crooked multiprocessing (AMP) and also symmetric multiprocessing (SMP). AMP needs a main core running an os to arrange jobs in other (second) cores. In SMP, the OS works on all cores, and also the scheduler is cost-free to draw jobs from a common listing.

ESP-IDF is the port of FreeRTOS for the ESP32, and also it sustains SMP. The ESP32 is a dual-core system (although, single-core variants exist). We look at exactly how the ESP32 design is set up and exactly how each core can access memory, resources, and also disturbs.

In ESP-IDF, we have the choice of pinning jobs to a core (to make sure that only that core may run a certain job) or setting a job to “no fondness” (to make sure that the job can run in either core). Using “no fondness” is easier to execute and also enhances CPU usage and also tons balancing without much initiative. It becomes hard to establish when specific jobs will certainly run, which makes forecasting target dates tougher. Because of this, lots of embedded developers like to pin tasks to cores, as it permits a higher degree of determinism.

We show exactly how to run tasks on either core in the ESP32 as well as established them to “no affinity.” Kernel things (e.g. semaphores, mutexes, and lines) work throughout cores with no modification, as the ESP32’s cores share memory.
