Tom Kreyche / ADT7410

Library for ADT7410 I2C temperature sensor. Use this instead of TMP102 when you need to measure temperatures lower than -40 degrees C. The device is guaranteed to work at -55 C but will actually read lower temps. See http://mbed.org/users/tkreyche/notebook/adt7140-i2c-temperature-sensor/ for more info.

Detailed Description

Example: 

 #include "mbed.h"
 #include "ADT7410.h"

 ADT7410 tempSens1(p28, p27, 0x90, 100000);

 int main() {

   // reset sensor to default values
   tempSens1.reset();

   // read the config register, should be default
   printf("Config: 0x%x\n", tempSens1.getConfig());

   // reduce sample rate to save power
   tempSens1.setConfig(ONE_SPS_MODE);

   // check config register was set correctly
   printf("Config: 0x%x\n", tempSens1.getConfig());

   // get temperature every two seconds
   while (1) {
       printf("Deg C %f\n", tempSens1.getTemp());
       wait(2);
   }
 }
