A change from 0 to 1 at the Reset (R) input of the timer while the timer is running resets the timer. This change also resets the time and the time base to zero. The timer is also reset if the signal state is 1 at the R input while the timer is not running.
问题找到了,请看以上解释。
只是有点奇怪,我只复位了一次,为何T保持不输出呢?
If anything can go wrong, it will.
