i have rfid reader module sending serial data 8n1 9600 baud at TTL format
and transmits 7 byte with one second cycle
i used serin2 and serin commads and received data and displayed them on display without synchronization data is changing and floats even it reads same tag
at proteus a make coomunication by simulating rfid reader as a pic628 sending 7 byte data like reader and
i will use hserin command
how can i synchronize pic877a with rfid reader which command must be used
at this kind of communication
