Golioth is showcasing 4 different "color coded" demos at the Zephyr Developer Summit. This post explains some of the concepts and what you can hope to learn when you stop by.
Menuconfig allows you to search, select, and enable features in Zephyr with ease. What happens when you want to save your configuration? This post shows you how.
The Zephyr interactive shell makes it really easy to test out i2c devices before writing any code. This demo shows how to scan for i2c addresses, issue commands directly, and use the sensor shell to poll your devices for all sensor channels available as part of Zephyr's sensor subsystem.
Ethernet support is built in to Zephyr with several different chipsets to choose from. Here's how to add a W5500 Ethernet chip to your project and configure the Zephyr drivers to use it.
Now you can set your Golioth credentials from the Zephyr device shell. You also have the option to pull them from the Golioth cloud and automatically send them to the device from a single command on the command line. These new features use the Zephyr settings subsystem where they are stored in flash memory so that they persist after rebooting.
I needed to build 15 sets of the same firmware, but pass three unique variables for each copy. Zephyr has a solution for this: the Kconfig system. You can declare your own custom symbol, then set the value by passing a command line argument at compile time. Here's how to do this with your own projects.
