Hi, plz help me
my RFID shows some garbage values
I have used code available in the project named
How to interface RFID with 8051 microcontroller (AT89C51)March 31, 2014 at 8:53 am #11430
LCD needs ASCII data to display anything on it. First check RFID with hyperterminal. If its showing values fine then tell me what are the ID numbers of your TAG.
We have to convert the digit into ASCII.

Can it be known from printed on it??

Hyper terminal is a computer communication software. Some uses of hyper terminal are:
1.Use a TCP/IP n/w to connect to systems on the internet or your n/w.
2.Use a Dial-up modem to dial into modem based systems.
3.Talk directly to many different types of devices using serial COM ports.

Hyperterminal is a communication tool. In windows xp, its by default installed but in Vista, 7 and 8, its not available. You can download it from website. Its easily available.
Once installed, you can connect RFID module with PC. for laptop you need usb to serial converter.
You can not identify unique tag number without reader. You need above mentioned setup.
If you find any difficulty, post us back.April 7, 2014 at 10:54 pm #11500
I got the serial number using HyperTerminal.April 8, 2014 at 8:39 pm #11508I get the card number using Hyperterminalcard numbers and numbers printed on card are;4E00706E3B6B –0007368251 112,282194F006DD849B3 — 0007198793 109,553694F006DD858A2 — 0007198808 109,553844F006DE25595 — 0007201365 109,57941i have tried all the code given in engineersgarage but still it shows garbage.plz plz plz help methank you..April 10, 2014 at 3:26 am #11510
Once you are getting with hyperterminal, lets move ahead step by step…!!
1. WAP to receive data serially on 8051… Send single byte data from hyperterminal and display it on LCD
2. Modify above progra, to receive data from hyperterminal and store in array and display it on LCD
3. Run the same code with RFID instead of HYPERTERMINAL…!!
All the best…!!!April 10, 2014 at 7:13 pm #11521
TH1=0xFD;TMOD=0x20;TR1=1;is this right code to recieve 8 bit data at 9600 baud??April 14, 2014 at 11:29 am #11550
The above code is only to initialise serial communication at 9600 baudrate.
To receive data use following function…
From above code, you will get data in variable a.April 15, 2014 at 12:06 pm #11557Pratik AgrawalParticipant
Hi, I have connected my rfid module with hyperterninal but it is not showing any data, what should i do?April 16, 2014 at 4:00 pm #11578
