Hi, there:

We connected PC keyboard with 8031 exactly same as Philips Application 434, When I pressed the key, I can get the key correctly.

But the problem is the keyboard that we are using contains a mag stripe reader on it, when I swipt the card, I can see a lot of chars are sending to CPU through Scope.. but I cann't get whole bunch of chars...

What I am planning to do is using Timer1 interrupt.
If timer1 timeout,
only one key is pressed
else
several keys are sent...

Anybody has a good idea?

Thanks

Frank
