]]> Abstract hardware interfaces in Zephyr https://blog.golioth.io/abstract-hardware-interfaces-in-zephyr/ Tue, 30 Apr 2024 15:12:50 +0000 https://goliothblogdev.wpenginepowered.com/?p=6786 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 […]

]]> Enabling power regulators automatically at boot in Zephyr https://blog.golioth.io/enabling-power-regulators-automatically-at-boot-in-zephyr/ Tue, 30 Jan 2024 16:11:14 +0000 https://goliothblogdev.wpenginepowered.com/?p=6158 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 […]
