hi guys,
i m doing pjt on attendance registry using RFID i got a RFID reader of digant technologies 125khz its interfaced to the UART of 89s52 i need to get the id from the tag as a string to the MC i succeed first time bt for next reading of id i need to reset the MC even if i have looped the reading part which works at time of serial interrupt. if i dont reset then garbage characters are read by MC. please help me out of this.. How? No information supplied. If you have written a program that requires you to reset the processor to get out the next ID, then don't you think you have to focus on that program? How many lines of information have you written, describing your program or the protocol you use in your program? How many source lines have you posted? So exactly how are we going to be able to help? What have you done, to figure out what the difference is between running the program from start, and continue running the program after the first code has been processed? What have you done to make sure that the program automatically starts from a similar state for each new tag ID (of course without considering resetting the processor)? |
