This post will detail a couple of different ways that an external antenna can be added to the Raspberry Pi 3.Share on Twitter ∙ Share on Facebook
The project is built on top of a LiFePO4wered/USB module. A small board is added with an MSP430G2131 microcontroller that takes care of monitoring input and output voltage, monitoring a PCB touch button, driving a power indicator LED and switching the load (the Raspberry Pi power). The microcontroller is also connected to the Pi’s I2C bus and monitors the Pi’s running state. The small board connects to 8 of the Pi’s GPIO pins but leaves the rest free to allow prototyping using fly leads.Share on Twitter ∙ Share on Facebook

There are multiple articles of how C++ is superior to C, that everything you can do in C you can do in C++ with a lot of extras, and that it should be used even with bare metal development. With this book, the author hopes to explain and show examples of how to implement soft real time systems without prioritising interrupts and without any need for complex real time task scheduling.
