In this post, we’ll walk through a couple methods for defining abstract hardware interfaces in Zephyr using the devicetree. You’ve probably seen abstract hardware interfaces implemented on popular development boards. Many boards provide a standardized connector interface like mikroBUS, Feather, MicroMod, Arduino UNO, etc. A defining characteristic of these interfaces is the ability to plug […]
Both Zephyr and Golioth have solutions for keeping track of multiple revisions of your hardware. Let’s walk through how to tell Zephyr there is both a “Rev A” and “Rev B” of your hardware. We’ll finish up by talking about how Golioth organizes OTA firmware updates for your different board revisions.
Learn how to create a portable Ozone project file that you can check into a git repository for future debugging of Zephyr applications.
The Modbus Vibration Monitor Reference Design allows you to immediately start talking to industrial devices using the Modbus protocol
Zephyr has a lot of tricks up its sleeve and most recently I used it to enable power regulators on a custom Golioth board. Perhaps the most interesting part of this is that it can be done entirely with the configuration code, without needing to dive in to any of the C files. And as […]
Ozone is a free graphical debugger for embedded firmware from SEGGER. It’s a powerful tool that can give you deep visibility into what’s happening in your embedded system. It’s especially useful when debugging nRF9160 Zephyr apps. Sorting out multiple threads and multi image builds can be tough, but this is the tool you want. In […]
We recently open-sourced the Golioth Reference Design TemplateĀ that we have been using internally as the starting point for our growing library of reference designs. Out of the box, the template provides an end-to-end working firmware example showcasing all of Goliothās key features. You can read more about whatās included in the Reference Design Template in […]
Golioth makes it easy to prototype, deploy, and manage vehicle telematics solutions using CAN bus and OBD-II. We also enable remote control, Over-The-Air upgrades, and device health monitoring in the automotive space.
There is a growing cultural awareness of the significant health impacts of poor air quality, especially in the wake of the COVID-19 pandemic and natural disasters like the wildfires in California. Indoor air quality is an often overlooked aspect of workplace health and safety. Yet it has been shown to have a significant impact on […]
Guest author Chris Wilson explains how a Golioth training inspired him to dig into how to add a new board definition in Zephyr
