I am doing a project on RFID based shopping cart...but now am having trouble connectiong RFID module to the microcontroller(AT89S52/AT89C52) am using.
The RFID module i purchased consists of EM-18 reader module and it has been connected to max232 and then to RS-232...so the module has rs232 output..now can i connect directly from rs232 to tx pin of microcontroller? or is there another way?
