How to Write a Simple Android Wear OS Hello World Application

Posted on by nerdhutblog

A few months back I treated myself to a new watch, and I decided to finally try a smartwatch. I haven’t thought that I’d use it as much as I ended up doing, but I noticed that the Android device lacks a few features that I’d previously found on the Apple Watch, most notably a native stocks app that helps keep track of my portfolio. Granted, I don’t know why I’d like to see my life savings disappear in real-time, but I decided to try and write a simple stock tracking app for Wear OS devices just for the sake of it. However, this article discusses how to get started with writing a custom program for Wear OS devices.

Introduction

In this part of the series I’m going to show you how to write a very basic C Host-Application that will run a program on the PRU of the BBB. This part of the series assumes that you have basic C skills. I’ll also include some useful links to the official ti API. Everything can be done with the tools that come with the BBB. Code Composer Studio (CCS) oder Eclipse are not needed needed but you can use them, if you want to.

BeagleBone Black programmable realtime unit (PRU) Hello World – Intro

Posted on by nerdhutblog

After receiving my BBB earlier this week, I was absolutely keen on using the Programmable Real-time (execution) Unit (or PRU), which is included in the main ARM-CPU of the BBB. But I soon realized that this is absolutely not a fun topic to start with, especially, if you are new to programming or embedded architectures. PRU programming can be pretty frustrating in the beginning and there is almost no community support or tutorials. But I’ll try to cover the topic as good as I can. Let’s get started!
