sensorInterfaces

NOTICE: If you would like to implement this library and use it on a Raspberry Pi or any other supported hwlib system, then follow these steps:

• In UltrasonicSensor.hpp uncomment "// #define HWLIB_ENABLED" (see code below)

// If we want to compile this code on a system supported by hwlib, then we have 
// to uncomment the define below. There's a check for this define in 
// "get_distance()" that will throw an exception if not defined. This way the 
// code will also be able to compile on non-supported hwlib systems.
#define HWLIB_ENABLED

• In your main, or anywhere you use a Sensor with hwlib, we need to include the correct file for the system we are using. See the hwlib documentation for more info. In our project it was used like this:

// The define below will be used to check whether or not we are on a hwlib
// supported system. If not, then hwlib related methods won't be used. 
// This way the code will be able to compile on non-supported hwlib
// systems as well.
#define HWLIB_ENABLED

#ifdef HWLIB_ENABLED
#include "hwlib.c"
#endif

int main() {    
    // If HWLIB_ENABLED was defined, we can call some methods specific for hwlib
    #ifdef HWLIB_ENABLED
    bcm2835_init();
    #endif
    
    return 0;
}

Documentation

You can find the documentation for Sensor Interfaces right here. Here you will find examples and links to other libraries.

IMPORTANT NOTE: This version is based on Clock and TimeStamp from ADT_Clock_merge. Those files will eventually end up in ADT, which is also how our CMakeList.txt works. For now you can copy Clock and TimeStamp from ADT_Clock_merge and paste them in the correct folders in ADT.
