摘要
本文介绍了一种新的用于DSP系统中的键盘处理方法。与单片机系统中常用的程序扫描键盘处理方式相比,这种定时-计数的方法能够有效地节约系统开销,且对键盘处理快速可靠。
A new approach of keyboard operation in Digital Signal Processor systems is developed in this paper. Compared with the traditional program-scan approach in the MCU system, the presented Timer-Counter approach in this paper is time-saving, besides it can process the keyboard quickly and accurately.
