aburch1 83:0d3572a8a851 23 @file : main.cpp
aburch1 83:0d3572a8a851 24 @authors : Radu Marcu, Jacob Williams, Niall Francis, Arron Burch
aburch1 83:0d3572a8a851 25
aburch1 83:0d3572a8a851 26 @section DESCRIPTION
aburch1 83:0d3572a8a851 27
aburch1 83:0d3572a8a851 28 This is the main class where the program runs on startup, this is
aburch1 83:0d3572a8a851 29 a multi-threaded application that will that make the ST F401 Nucleo Target board
aburch1 83:0d3572a8a851 30 take periodic measurements of senor data, including temperature,
aburch1 83:0d3572a8a851 31 pressure and humidity, at a fixed set sample rate. A max of 120 measurements are stored
aburch1 83:0d3572a8a851 32 within RAM at any one time, available to be printed to a termial output via a serial port
aburch1 83:0d3572a8a851 33 connection.
aburch1 83:0d3572a8a851 34 Once 120 measurements are stored, the oldest measurements are overwritten using a circular
aburch1 83:0d3572a8a851 35 buffer, so that the most recent 120 measurements can always be stored on the device.
aburch1 83:0d3572a8a851 36 The application can provide logging data when measurements are taken if logging is turned
aburch1 83:0d3572a8a851 37 on using the logging command (See readme.md).
aburch1 83:0d3572a8a851 38 The application has been written to reduce power consumption where possible by utilising
aburch1 83:0d3572a8a851 39 Thread signals and sleeping when not in use.
aburch1 83:0d3572a8a851 40 Serial Communications are handled within a sepearate thread to ensure that no action will
aburch1 83:0d3572a8a851 41 block or interrupt the CPU when measuring samples.
aburch1 83:0d3572a8a851 42 The serial communications use a priority system, allowing errors to be printed with a higher
aburch1 83:0d3572a8a851 43 priority than logging messages and the application to be terminated and reset by user input
aburch1 83:0d3572a8a851 44 if required.
