能较为准确的计时并将时钟、分钟、秒钟显示到数码管上，此实验是利用DSP的定时器做时钟，并将时钟、分钟、秒钟显示到数码管上。编写程序时先编写定时器初始化程序，运用DSP定时器来定时计数，并通过定时器中断服务程序刷新数码管。其硬件连接原理图和I/O端口地址译码请参考实验五输入输出模块中的数码显示输出模块。-Can be more accurate timing and the clock, minutes, seconds display to digital control, this experiment is done using DSP timer clock, the clock, minutes, seconds display to digital pipe. Preparation program to prepare the first timer initialization procedure, the use of DSP timer to count from time to time, and through the timer interrupt service routine refresh digital tube. Schematic diagram of the hardware connection and the I/O port address decoding Please refer to experiment five input and output module digital display output module.
