基于C的PS2键盘解码实验源码，属于51单片机的范畴，注意:如SHIFT+G为12H 34H F0H 34H F0H 12H，也就是说shift的通码+G的通码+shift的断码+G的断码，当中断10次后表示一帧数据收完，清变量准备下一次接收，当键松开时不处理判码，如G 34H F0H 34H 那么第二个34H不会被处理，再次注意：若晶振速度太高可以在这后加小的延时。-C-based PS2 keyboard decoding experimental source, are 51 areas of SCM, Note: SHIFT+ G to 12H 34H F0H 34H F0H 12H, that shift the pass code+ G' s pass code+ shift+ G code of the broken-off code, when the interrupt 10 times that a data collection finished, ready for the next variable to receive clear, when the key is released, does not deal with sub-codes, such as G 34H F0H 34H 34H then the second will not be processed again Note: If the high crystal speed can be added in this small delay.
