Integrating the accelerometer of the AM335X Sitara Starter Kit in a QT application

This paper presents the development of a Qt application for the AM335x Sitara Starter Kit system (referred in the following as AM335x SK for the sake of notation). The application reads data from the AM335x SK's accelerometer, displays the three axes acceleration data on a Qt widget and determines the orientation of the AM335x SK (one of the six possible) as a function of the values of the three accelerations. This orientation is displayed in real-time on another Qt widget. Also, the Qt application sends the current orientation of the system to a MSP430G2553 microcontroller via Bluetooth, to be displayed on a 2×16 LCD. For this communication, the Bluetooth module of the AM335x SK is used, while MSP430G2553 is supplied with a HC05 module. Some buttons which allows the starting or the ending of the entire application or only the Bluetooth communication part are included in the window of the Qt application.
