reading rfid 125 khz

[daredevil3]

Hy everybody. I build a circuit rfid.
The reader frequency is 125kHz, the output from the reader sends pulses to the pin RA4 pic16f887 with the internal oscillator set to 8MHz.
If a tag is present, the pulses conform to a bit rate of 512us per bit.
When a tag is present it will transmit its code over and over.
The code will consist of long pulses (about 512us each = 1 TTL)
and short ones (about 256us = 0 TTL)
Can you help me to write a source code for pic16f887 that receive data to RX pin (RA4) and display it on LCD 16x2?
Thank you very much

Sorry for my english

Hi,

you might want to have a look at this: Ficara Emilio Pietro Giovanni - Personal Site - Home Page

There is a project for an RFID 125KHz door opener. It uses an ATMEL ATtiny2313.

Thank you for replay, I search source code, I have found only hex.
