Data Structures
Here are the data structures with brief descriptions:
| AbstractHandler | Inherited by all handlers. It forms the basis of any handler, by having a simple run function, called in main.cpp, and a setRequest function which is used to set a request specific to the reimplemented class |
| CircBuff | Writes in and reads out byte arrays into a circular buffer |
| Dht22Result | The Dht22Result struct is the information read from a Dht22 Grove sensor |
| GprsHandler | Saves recipients and looks after incoming and outgoing messages |
| GroveDht22 | Handles the interface to the DHT22 humidity and temperature sensor |
| MeasurementHandler | Forms the link between data generation and data output, and stores settings |
| MyTimers | Creates a Ticker and decrements a collection of unsigned longs that act as timers across the program |
| SdHandler | Writes messages to file and handles SD card status |
| UsbComms | Handles input and output for the serial port connected to a PC The main run() function cycles through checking for input and copying to a buffer to be handled, and checking the output buffer to see if there is anything to be sent out |
