messi1 0:a1ed9ce625d4 2 * Used for interfacing the TMP007 with the mbed.
messi1 0:a1ed9ce625d4 3 *
messi1 0:a1ed9ce625d4 4 * Example:
messi1 0:a1ed9ce625d4 5 * @code
messi1 0:a1ed9ce625d4 6 * #include "mbed.h"
messi1 0:a1ed9ce625d4 7 * #include "TMP007.h"
messi1 0:a1ed9ce625d4 8
messi1 0:a1ed9ce625d4 9 * #define Address 0x40 // depending on pin ADR0 and ADR1 it can be either 0x40, 0x41, 0x44 or 0x45
messi1 0:a1ed9ce625d4 10 *
messi1 0:a1ed9ce625d4 11 * TMP007 sensor(p9, p10, Address);
messi1 0:a1ed9ce625d4 12 *
messi1 0:a1ed9ce625d4 13 * int main()
messi1 0:a1ed9ce625d4 14 * {
messi1 0:a1ed9ce625d4 15 * while(1) {
messi1 0:a1ed9ce625d4 16 * printf("TTemperature: %f F \r \n", sensor.readObjTempF(Address));
messi1 0:a1ed9ce625d4 17 * wait(0.5);
messi1 0:a1ed9ce625d4 18 * }
messi1 0:a1ed9ce625d4 19 * }
