要点有3：
1. TMR1中断，每次中断显示led的一位，且将键盘的状态存储链推进一步。
2. TMR1中断处理中，为便利实现各位的显示，采用了寄存器4(FSR)间接寻址方式。
3. 键盘用多级状态机方式，不会为按键判断占用机时，整体显示和键盘响应非常“干脆”；用“下键”标志防止重复读键，从而对于下键和抬键的开关抖动都能够有效抑制。-Main points of 3: 1. TMR1 interrupt, each led one of the interrupt display, and store the state of the keyboard chain to push further. 2. TMR1 interrupt handling, in order to facilitate the realization of you display, using a register 4 (FSR) indirect addressing mode. 3. Keyboard with multi-level state machine approach, will not take up machine for the key judgments, the overall display and the keyboard response is " simply" use " under the key" symbol to prevent duplicate reading keys to carry keys for the next key and the switch jitter are effectively suppressed.
