#8814 - RE: Level Triggered Interrupt applications. |
Hi Fran, have a look at what I've posted in the thread 'connect magnetic card reader to 8051'. The reader data, available at the /RDD (data pin), has to be sampled synchronously in the falling edge of /RCP (clock) signal, so it's a good idea to connect /RCP to the /INT pin. The irq service routine would read the /RDD (data pin), move bit to carry, RLC, .... and RETI Saludos :) Txip. |
