- * Dallas' DS1820 family temperature sensor.
- * This library depends on the OneWire library (Dallas' 1-Wire bus protocol implementation)
- * available at <http://developer.mbed.org/users/hudakz/code/OneWire/>
- *
- * Example of use:
- * 
- * Single sensor.
- *
- * #include "mbed.h"
- * #include "DS1820.h"
- * 
- * Serial      pc(USBTX, USBRX);
- * DigitalOut  led(LED1);
- * OneWire     oneWire(D8);    // substitute D8 with actual mbed pin name connected 1-wire bus
- * float       temp = 0;
- * int         result = 0;
- * 
- * int main()
- * {
- *     pc.printf("\r\n--Starting--\r\n");
- *     if (ds1820.begin()) {
- *         while (1) {
- *             ds1820.startConversion();   // start temperature conversion from analog to digital
- *             wait(1.0);                  // let DS1820 complete the temperature conversion
- *             result = ds1820.read(temp); // read temperature from DS1820 and perform cyclic redundancy check (CRC)
- *             switch (result) {
- *                 case 0:                 // no errors -> 'temp' contains the value of measured temperature
- *                     pc.printf("temp = %3.1f%cC\r\n", temp, 176);
- *                     break;
- * 
- *                 case 1:                 // no sensor present -> 'temp' is not updated
- *                     pc.printf("no sensor present\n\r");
- *                     break;
- * 
- *                 case 2:                 // CRC error -> 'temp' is not updated
- *                     pc.printf("CRC error\r\n");
