PHILIP驱动器PCF8576驱动程序，可驱动4×40个点

设计使得原本需要14个IO接口的键盘显示少用了9个单片机IO接口,虽然该设计的优势在本实验中没有完全体现出来,但若在现代工业设计中应用此方案,在对引脚需要较大的产品中其优点将体现得淋漓尽致。.-Design makes the original needs 14 IO interface shows the use of a keyboard 9 Singlechip IO interface, although the advantages of the design in this experiment did not fully reflected, but in modern industrial design in the application of this program in the pairs of primers Products feet larger in its merits and will be reflected most vividly. .
