中文说明：在以dspic30f4011为主芯片的控制板上，对于需要预置或者在以后操作中需要写入的数据可以通过EEPROM来操作。本源码的控制对象是一台电焊机，在开机之前，EEPROM里面需要预置一些电流、电压、推力电流、以及以后需要开发的其他功能的参数（如电流上升时间、电流缓降时间以及脉宽时间参数），本例以手工焊的电流、电压为预置的数据。在焊机开始焊接前，如果需要操作面板，那么在操作完面板后，新的数据将会载入EEPROM，来替换旧的数据，从而实现数据的更新。
English Description：
In the control panel with dsPIC30F4011 as the main chip, the need for the preset or need to write after the operation data can be operated by EEPROM. The control object of this source is a Teclast welder, before starting, the inside of the EEPROM need to preset some current, voltage, current, thrust and other functions need to be developed parameters (such as the current rise time, fall time and pulse current delay time parameter), in this example, the current manual welding voltage to a preset data. In a welder before welding begins, if need the operation panel, then in the end after the operation panel, the new data will be loaded into the EEPROM, to replace the old data, and realize data update.
