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
