An increasing number of modern-day geolocation systems are based on linux. A framework called gpsd enables a simple mechanism to get geo-location data from location sensors. Check out this post that talks about using gpsd.
Tinkering with the Jupiter Nano: Part 3 – A Complete Guide To Enabling Yocto Support!
Yocto is the most preferred build system used by embedded linux developers across the world owing to its layered and modular nature. In this post, we see how to add Yocto support for this board and then build a minimal image to test this support.
Tinkering with the Jupiter Nano: Part 2 – Understanding the linux boot!
The Jupiter Nano ships with a debian image. However, not everyone wants to use debian. Also, something like Yocto allows you to heavily customize your linux image as well as reduce your boot time considerably. Check out this post that lays the foundation for creating a Yocto image.
Tinkering with the Jupiter Nano: Part 1 – Is it a microcontroller or a low-power linux machine?!
The Jupiter Nano is an open-source hardware based on an awesome MPU product from Microchip called the SAMA5D27C-LD1G. The boards exposes a lot of IO in spite of a tiny form-factor, boots a full-fledged linux distro as well as can support microcontroller-like development flow.
Raspberry Pi + ATECC608: Part 3 – Using PKCS#11 Token For MQTT Pub-Sub with AWS IoT Core
TLDR: In their run-time engine code, Amazon provides the ability to use PKCS#11 tokens to perform mutual TLS authentication with the cloud. Here, we use Microchip ATECC608 as a PKCS#11 token. By using Microchip's ATECC608, the act of generating and storing keys and certificates is rendered unnecessary and the device-to-cloud on-boarding is a breeze! Welcome … Continue reading Raspberry Pi + ATECC608: Part 3 – Using PKCS#11 Token For MQTT Pub-Sub with AWS IoT Core
Like the RPi Zero? You will love the Jupiter Nano!
I recently came across a wonderful, tiny, fully open-source board on CrowdSupply and loved it. Here's my take on this!
