| Abstract: | The main control and communicating interface circuits of the multi- rate watt- hour meter based on MSP430 single chip isdiscussed in detail in this paper. The principle of the multi- rate watt- hour meter is also introduced. The measuring of watt- hourhas higher accuracy by the special AD7755. Addresses and data of the clock/calendar and data storage circuits are transferred serial-ly via the two- line bidirectional I2C bus which simplifies circuit and enhances the reliability. Software and reliability design of this system are also mentioned. |
| Keywords: | multi-rate watt-hour meter MSP430 single chip communicating interface |
