#169635 - rfid help needed |
it is required from me to build a code for 8052 that reads a number sent by an rfid tag.
the design is based on the ic (u2270 ) that reads from the antenna and sends te code to 8052. i had a problem that i found that even in case of te absense of a TAG that there is a signal on the output of ic and this is not a regular signal to be able to distinguis it from the code sent by the TAG the circuit that i use is te 1st application mentioned in the datasheet of (u2270) by Atmel inc.can any one help me? thank you |
