数控直流电流源程序

1、-作者xxxx-日期xxxx数控直流电流源程序【精品文档】/*跳线说明：1）将EXP-LM3S811板卡上JP9、JP13跳至左侧（短接1-2）；2）将EXP-min_system_board板卡上JP13、JP14、JP15、JP16跳至右侧（短接2-3。操作过程：1）将EXP-min_system_board板卡上K1拨动开关拨至ON状态，给液晶上电；2）调节RP1电位器，使液晶有合适的背光；3）上电，编译并下载程序，复位后全速运行程序；观察液晶显示的内容，再修改程序使之显示自己的内容。*/#include systemInit.h#include ADS7886.h#include TL
