#96144 - INt on pin level change Responding to: ???'s previous message |
Also do you guys know of a chip that can interrupt the CPU on the status change of a port? I interfaced my 16F628 with a PC keyboard and it would be nice to interrupt the CPU when the keyboard wants to send something instead of waiting for the keyboard to send (and locking the CPU in a loop while waiting).
You can use the KBI (keyboard interrupt) on the LPC9xx family (and others) and/or you can use the INT0/INT1 pins to sense the interrupt. It should be no big deal and you should be feeling a great joy at this time for being able to use an architecture as "modern" as the 8051 (compared to the PIC). GB |
