Piece machine pin function is described as follows:
VCC: supply voltage；
GND: ground connection；
P0 mouthfuls: P0 mouthful is two-way I/O mouthfuls of 8 drains open circuit, and every foot can absorb 8TTL gate current, when P1 mouthfuls of pin
When writing 1 for the first time, it is defined as high resistant input.P0 can be used in external program data storage, it can be defined as data/
The 8th of address.In FIASH programming, P0 mouthfuls are used as true form input port, and when FIASH is verified, P0 exports true form, this
When P0 outside must be raised；
P1 mouthfuls: P1 mouthful is that internal 8 for providing pull-up resistor are I/O mouthfuls two-way, and P1 mouthfuls of buffers can receive output
4TTL gate current, after P1 mouthfuls of pin write-ins 1, it is high for being pulled up by inside, can be used as inputting, and P1 mouthfuls are low level by outside drop-down
When, electric current will be exported, this is because the reason of internal pull-up, when FLASH is programmed and is verified, P1 mouthfuls connect as the 8th bit address
It receives；
P2 mouthfuls: P2 mouthful 8 for an internal pull-up resistor I/O mouthful two-way, and P2 mouthfuls of buffers are receivable, export 4 TTL
Gate current, when P2 mouthfuls by one writing, pin is drawn high by internal pull-up resistor, and as input, and therefore as input when,
P2 mouthfuls of pin is dragged down by outside, will export electric current, this is because the reason of internal pull-up, works as P2 mouthfuls and be used for external program storage

After P3 mouthfuls of write-ins " 1 ", they are high level by inside pull-up, and are used as input, as input, since outside drop-down is low electricity
Flat, P3 mouthfuls will export electric current (ILL), this is because the reason of pull-up；
RST: input is resetted, when oscillator reset device, to keep the level time of two machine cycles of RST foot；
ALE/PROG: when accessing external memory, the output level that address latch allows is used for the status of latch address
Byte, during FLASH programming, this pin is for inputting programming pulse, and usually, the end ALE is exported with constant frequency cycle
Positive pulse signal, this frequency are the 1/6 of oscillator frequency, therefore it can be used as to the pulse of outside output or for timing mesh
, it is noted, however, that an ALE pulse will be skipped whenever being used as external data memory, such as want to forbid that ALE's is defeated
0 can be set on the address SFR8EH out, at this point, ALE is only executing MOVX, MOVC instruction is that ALE just works, in addition, this draws
Foot is slightly drawn high.If microprocessor is forbidden in external execution state ALE, set is invalid；
/ PSEN: the gating signal of external program memory, by during external program memory fetching, each machine is all
Phase twice/PSEN is effective, but when accessing external data memory, effective/PSEN signal will not occur twice for this；
/ EA/VPP: when/EA keeps low level, then external program memory (0000H-FFFFH) during this period, regardless of
Whether internal program memory is had, when paying attention to cipher mode 1, internal lock is RESET by/EA, when/the end EA holding high level
When, internal program memory around here, during FLASH programming, this pin is also used for applying 12V programming power supply；
XTAL1: the reversed input of monofier and the input of internal clocking operating circuit；
XTAL2: carry out the output of self-reversal oscillator.

The oscillator of composition, XTAL1 and XTAL2 are respectively the input terminal and output end of oscillating circuit, and clock can have internal or external
It generates, the external timing element on XTAL1 and XTAL2 pin, internal oscillator circuit will generate self-oscillation, in the present embodiment
The shunt-resonant circuit that the timing element used forms for quartz crystal and capacitor, crystal oscillator frequency use 12MHZ, the electricity of C1, C2
Capacitance takes 30pF, and the size of capacitor plays frequency trim.
Specifically, AT89C51 single-chip microcontroller start operation when or the when of crash need to be reset, make CPU and other
Functional component is in a determining original state, and starts to work from this state, and there are many reset modes for single-chip microcontroller, commonly uses
Reset operation have an electrification reset and hand-reset mode, the present embodiment uses simplest electrification reset mode, and circuit is as schemed
Shown in 11, electrification reset is realized by the capacitor charging of external reset circuit, and the reset signal that reset circuit generates is (high
Level is effective) internal reset circuit is sent to by RST pin, AT89C51 single-chip microcontroller is resetted, reset signal will continue
More than two machine cycles (24 clock cycle), it can just make AT89C51 single-chip microcontroller reliable reset, upon power-up, C1 is equivalent to
Short circuit will cause erroneous resets when encountering interference sometimes, can add a decoupling capacitor in reset terminal, can obtain good effect.
So that explanation, forward direction lights a LED, at least needs 10~20mA, if electric current is not big enough, LED is inadequate
Greatly, but regardless of being the I/O mouth of AT89C51 or the output end of TTL, CMOS, high state output electric current be not it is very high, but 1
~2mA, therefore it is difficult direct high state driving LED, additional driving circuit is at this time just needed, therefore 74LS245 is added
