时钟芯片在轴向变量柱塞泵控制器中的应用

Application of Clock Chip in Controller of Axial Variable Plunger Pump

基于I2C总线,对轴向变量柱塞泵控制器的时钟/日历模块进行了开发,重点介绍了该模块从底层到顶层的汇编语言程序的开发方法和思路。联合调试结果表明:对轴向变量柱塞泵控制器时钟/日历模块的开发达到了预期的功能要求,通过该模块不仅可以给整个系统提供时钟/日历参考,还可以对时钟/日历信息进行校正和更新。

Clock/calendar module of the controller of axial variable plunger pump was developed based on I^2C bus, in which, development methods and thoughts of assembly language program from the bottom layer to the top layer of the module were introduced in detail. Combined debugging results indicate that the development of clock/calendar module of the controller of axial variable plunger pump has attained the preplanned function requirements, and clock/ calendar reference can not only be provided, but also clock/calendar messages can be revised and renewed by means of this module.
