Hardware

Your ESP32-C3 can act as a secondary modem for any type of primary processor. This post shows how to program and utilize the ESP-AT default firmware.

As we previously wrote about, we attended the first Embedded World North America, held in Austin Texas...

If you have ever tried communicating with a device on a private network, you may have encountered Network Address Translation (NAT). Because the number of connected devices has long outpaced the number of unique addresses in the IPv4 address space, public IP addresses have to be shared between devices. This introduces a number of challenges.

Did you know that Zephyr doesn't have a plain old GPIO example? The closest thing is the blinky example that controls LEDs. Why is that? Zephyr expects you to write your own devicetree bindings. It's not that hard, and it's the topic of today's post.

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.

Golioth's new partnership with Memfault enables device data to seamlessly flow back to the cloud over CoAP and out to the Memfault platform. An upcoming webinar with Memfault and NXP will show how it's done.

Golioth Reference Designs now include purchasable hardware setups that mirror all functionality on our custom hardware solution....

Golioth's new custom hardware is an ePaper-based user interface that works with all of our reference designs. All it takes is Qwiic cable to connect to the i2c bus, and sensor readings and other information begins streaming to the face plate. Let's take a look!
