Inzichten over engineering,elektronica, firmware en embedded systemen
De Cyber Resilience Act schrijft het resultaat voor, niet de techniek. Drie concrete eisen uitgelicht: veilige firmware-updates, logging versus dataminimalisatie en de SBOM.
De EU Cyber Resilience Act stelt harde eisen aan beveiliging van connected producten. Het Jitter platform voorziet hier al in met MQTT over TLS en X.509-authenticatie per device.
Alles in een klap omgooien klinkt als de snelste route, maar stapsgewijs moderniseren is bijna altijd de betere strategie. Waarom? Je werkt altijd vanuit een werkend geheel en kunt veel eerder testen en bijsturen.
Iets nieuws vanaf nul ontwikkelen is zoveel makkelijker dan bestaande systemen aanpassen. Maar die luxe heb je niet als je een draaiend systeem moet moderniseren.
State machines have an image of being cumbersome and tricky to debug. But this doesn't have to be the case! In this post we show how we use them and why the Rust language makes this so reliable and painless to use.
As a PCB designer, the so-called 'ground plane' is your best friend. It makes layout easier, improves EMC performance, and as a bonus you get increased signal integrity. But be carefull to keep the ground plane intact...
When I got started in PCB design, layout seemed like the easy part. The CAD software enforces the schematics, so you just need to puzzle everything together until all connections are made. Right?
A Rust driver crate for the ADXL355 digital accelerometer. This driver accepts an embedded-hal SPI interface and a GPIO OutputPin. It implements the Accelerometer Trait so you can easily obtain both raw sensor data and scaled-to-Standard-gravity sensor data.
MicroSD cards. They are used in phones, cameras and all kinds of devices. A no-brainer to add some extra storage capacity to your project. They are advertised by their average read/write speed in MB/s. But there is a metric that is at least as important for certain applications: latency...
Updating the Bill Of Materials manually is tedious and error-prone, especially for PCB designs with many different components. The alternative is exporting a new BOM after every design change.
