Detailed Description

test_TMP102 Class Library to provide very simple interface for mbed

Example: 

 #include "mbed.h"
 #include "test_TMP102.h"

 // make test_TMP102 instance using GPIO pin name.
 test_TMP102 temp0(dp4,dp5);

 // make test_TMP102 instance using I2C object.
 I2C i2c(dp4,dp5);
 test_TMP102 temp1(i2c);

 int main()
 {
     float t0,t1;

     i2c.frequency(400*1000);

     while(1) {
         t0=temp0;
         t1=temp1;
         printf("Temp: %7.3f, %7.3f\r\n", t0, t1);
         wait(1.0);
     }
 }
