中文摘要：

基于SEED—DEC2407的控制模板设计和开发了一个电阻点焊控制器。先对DSP控制模板的各功能模块和软件集成开发环境进行了简要介绍，然后根据电阻点焊过程的功能要求，设计了电阻点焊控制器的总程序框图，并分别对UART模块、定时器模块、D／A模块、I／O模块进行了软件编程与调试，最后对点焊控制器的总程序进行调试与应用。实践结果表明，本文设计的电阻点焊控制器是可行的。

英文摘要：

A resistance spot weld controller was developed based on SEED-DEC2407 control board. The functional modules of the control board and its software integrated development environment were introduced. The total program frame of resistance spot weld controller was designed according to the requirements of resistance spot weld process, and the programming and debugging were performed respectively for the modules of UART, the timer, D/A and I/O. Finally, the total program of the controller was debugged and tested, and the results show that the developed resistance spot weld controller is practical.
