Delay on stm32 , worked on STMicro STM32F103 ARm Cortex M3 , by using C Language .

This is part of code for test delay functions made it by me, i used some of kind memory function to remember when a switch is pressed and when is released, and go trhough a toggle function to turn on/off a led on the board, the trainning board i used

采用的主控芯片LPC1768系列CORTEX-M3内核处理器，时钟晶振XT=12MHZ，系统时钟96MHZ，外部时钟PLCK.定时器匹配 查询定时器停止位、定时器匹配 查询中断标志:本程序利用定时器产生1S的时间中断，同时切换LED状态，采用查询方式 定时器匹配 定时器硬件延时函数：本程序使用定时器作为硬件延时函数；定时器匹配 定时器硬件延时函数： 本程序利用定时器产生1S的时间中断，同时切换LED状态，采用中断方式；定时器匹配输出：本程序利用定时器产生1S的时间中断，同时切换LED状态-Usi

适用于M3内核的STM32软延时设定模块，提供较为精确的软件延时(STM32 soft delay setting module for M3 kernel, providing more accurate software delay)
