jensstruemper 0:755bd47fd6be 33 * This recent implementation wraps the example code of Jonathan Jones into a library.
jensstruemper 0:755bd47fd6be 34 *
jensstruemper 0:755bd47fd6be 35 * The float read_temp(int select) memeber function will take one argument:
jensstruemper 0:755bd47fd6be 36 * <ul>
jensstruemper 0:755bd47fd6be 37 * <li> "0" to return ambient temperature </li>
jensstruemper 0:755bd47fd6be 38 * <li> "1" to retunr object temperature </li>
jensstruemper 0:755bd47fd6be 39 * </ul>
jensstruemper 0:755bd47fd6be 40 *
jensstruemper 0:755bd47fd6be 41 * Example:
jensstruemper 0:755bd47fd6be 42 * @code
jensstruemper 0:755bd47fd6be 43 * #include "mbed.h"
jensstruemper 0:755bd47fd6be 44 * #include "MLX90614.h"
jensstruemper 0:755bd47fd6be 45 *
jensstruemper 0:755bd47fd6be 46 * I2C i2c(p16, p17); //I2C_SDA, I2C_SCL
jensstruemper 0:755bd47fd6be 47 * MLX90614 mlx90614(&i2c);
jensstruemper 0:755bd47fd6be 48 *
jensstruemper 0:755bd47fd6be 49 * float temp;
jensstruemper 0:755bd47fd6be 50 * int select; // 0 = object temp, 1 = ambient temp
jensstruemper 0:755bd47fd6be 51 *
jensstruemper 0:755bd47fd6be 52 * int main(){
