The purpose of this tutorial is to expound my notes on the studies I have done on the use of nRF51, but also serve for the nRF52, and thus share with the beginner as I of the Portuguese language. This tutorial is continuity in the [previous tutorial] (https://devzone.nordicsemi.com/blogs/1193/configuring-the-eclipse-oxygen-for-development/).The SDK 10 is chosen because there is still the S110 version of SoftDevice for the nRF51.If you find any errors, be sure to let me know, because they are annotations m...

This tutorial aims to help Portuguese language beginners, like me, with the nRF5x family and who chose to use Eclipse as a development tool.The tutorial will be very simple and we will use the Eclipse Oxygen and the GNU MCU Plugin, in addition to GCC 6.There will also be separate tutorials for each step, in this will be the only configuration of Eclipse for use of the Tools and soon thereafter will create another showing how to create a project using one of the examples, and finally a third demonstrating ...
