A "Swiss Army Knife" Watch

Project Lead German Rivera     Location Sunnyvale, USA

The purpose of this project is to develop the embedded software of a "Swiss Army Knife" watch in Ada 2012 on the Hexiwear wearable device (http://www.hexiwear.com). The Hexiwear is an IoT wearable development board that has two NXP Kinetis microcontrollers. One is a K64F (Cortex-M4 core) for running the main embedded application software. The other one is a KW40 (Cortex M0+ core) for running a wireless connectivity stack (e.g., Bluetooth BLE or Thread). The Hexiwear board also has a rich set of peripherals, including OLED display, accelerometer, magnetometer, gryroscope, pressure sensor, temperature sensor and heart-rate sensor. The motivation of this project is two-fold. First, to demonstrate that the whole bare-metal embedded software of this kind of IoT wearable device can be developed 100% in Ada, from the lowest level device drivers all the way up to the application-specific code. Second, software development for this project will produce a series of reusable modules that can be used in the future as a basis for creating "labs" for teaching an Ada 2012 embedded software development class using the Hexiwear platform. Given the fact that the Hexiwear platform is a very attractive platform for embedded software development, its appeal can be used to attract more embedded developers to learn Ada. The scope of the project will be to develop only the firmware that runs on the application microcontroller (K64F). Ada drivers for Hexiwear-specific peripherals need to be developed from scratch, as they are not supported by AdaCore's Ada drivers library. Also, since I will be using the GNAT GPL 2017 Ada compiler and the GNAT GPL distribution does not include a port of the Ada Runtime for the Hexiwear board, the GNAT GPL 2017 Ada runtime needs to be ported to the Hexiwear board.
