2.8.2 Demonstration of Program
Assuming the hardware has been configured correctly, the µPD70F3318Y MCU has been
programmed with the demonstration program code, demonstration is as follows:
5. On Reset of the CPU, observe two dashes on the LED. Press SW2 to read and display the
temperature as sensed by the probe attached to the MAX6627 device. The temperature will be
displayed serially through the LED. For example, the temperature +35ºC would be displayed as:
− 3 5. blank tens digit, units digit with decimal point
− 5. 0 units digit with decimal point, tenths digit
− 0 0 tenths digit, hundredths digit
6. Press SW3 to read and display the temperature as sensed by DS1722 device. The temperature will
be displayed serially through the LED. For example, the temperature +27.25ºC would be
displayed as:
− 2 7. blank tens digit, units digit with decimal point
− 7. 2 units digit with decimal point, tenths digit
− 2 5 tenths digit, hundredths digit
7. Change the temperature at the devices, and check the temperature as reported by pressing SW2
and SW3.
