摘要
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 developedin this paper. Compared with the traditional program-scan approach in the MCU system, the pre-sented timer-counter approach in this paper is time-saving, besides it can process the keyboardquickly and accurately.
