FatFs06.rar
FatFs is a generic file system module to implement the FAT file system to small embedded systems. The FatFs is written in compliance with ANSI C, therefore it is independent of hardware architecture. It can be incorporated into cheap microcontrollers, such as 8051, PIC, AVR, SH, Z80, H8, ARM and etc..., without any change.

(1) 硬件電路中用P1.0~P1.7控制按鍵,其中P1.0~P1.3掃描行,P1.4~P1.7掃描列。
(2) 用P0.0~P0.7,P2.0~P2.7控制LED,其中P0.0~P0.7控制七段碼a,b,c,d,e,f,g,用P2.0~P2.7為數碼管位選信號。
(3) 用,P2.0~P2.2作為LCD的RS,R/W,E的控制信號。用P0.0~P0.7作為LCD的D0~D7的控制信號。
(4) 用P3.7口控制蜂鳴器(J2,J4斷開,J3短接)。
(5) 電路為12MHZ晶振頻率工作,起振電路中C1,C2均為30pf。
