The Parameters Modification Device of Digital Automatic Voltage Regulator

摘要

The device, which can modify and save the parameters, is proposed in the paper. The parameters are modified by the four keypads and are saved in the EEPROM. The EEPROM communicates with CPU via the Inter-Integrated Circuit bus interface, and The program is wiitten on the Inter-Integrated Circuit bus protocol. In addition, the display is connected to the CPU serial port. The obvious advantage of the device is using a few of CPU ports, so that the device can be transplanted to the other control systems.
