UART interface and MAX232
I am interfacing RFID with PSOC4 pioneer kit. The RFID output is obtained thorugh a DB9 connector, using UART interface. When I connect the pins directly i am not getting the correct values but only junk values. Should i be connecting a max 232 IC for interfacing the RFID reader?? Is there any other solution ?? What are the things to be taken care while doing it ?? can anyone give an idea how should I proceed ?
