DESCRIPTION Use MCS-51 MCU to make the controller to accomplish drive with the RC500
Can operate the Mifare One
It is very few to occup resources (RAM ), only 19 byte, very favorable for reduction of cost
Use RS232 and PC link to each other, through run DEMO process to operate the computer that can read and write the card.
Can be used as Mifare one read and write device.
Integrated design (The antenna can be used alone)
Offered two sets of source code of C51 and A51 with same function.

INTRODUCTION
OF HARDWARE CPU adopt MCS51

RF circuit include RC500 that produce of PHILIPS and RF antenna that set in the developboard
RS232 interface

INTRODUCTION
OF SOFTWARE PC DEMO PROCESS
Operate the developboard through inputting the command, read the content in cards, show on the interface, or write the information imported to on the card.

DEVELOPBOARD PROGRAM
1) Communication program
Intermit the receive and dispatch control, storage the information that received from the serial interface to the buffer, or send the information of the buffer area to the serial line.

2) Command process
Interpret of the received command
3) Card operating program
According to the received the command to operating the card, make use of exhausting possible few resource, not occupy the CPU'intermit, and assure the card can quit safely from function when move the area of the read and write in any time.
Take the writing card function of the compilation for example :
Except a working register group, just occupy 1 digit of sign and 19 bytes EMS cell (include the 16 bytes are written into the data).Whether C51 or program of com-pilation may write into the 89C52, if not consider with occupy the PC communication resource, May even write into the 89C51.

Include the function as follows :
Initialize RC500, seek card, defend collide, select card, switch format of the KEY, transmit KEY, validate KEY, deduct money and add money, move the wallet to the buffer area, copy the wallet of the buffer area, card dormancy, read RC500-EEPROM, write RC500-EEPROM, resume leave factory setting of RC500, tune the use-defined RC500, tune the KEY of RC500－EEPROM, startup the antenna, close up the antenna.
