I am trying to interface a magnetic card reader with the mini-max/51-c. I am connecting the card reader to p2.7-p2.5 which is typically used for the keypad. When a card is swept trough the card reader data is supposed to be sent trough p2.7 serially. I was wondering if any knows a way in which I could display the data being sent through P2.7 on the LCD screen or save the incoming data in a string or array.
any amount of help would be appreciated
