Hi. Im 15, and I live in Argentina. Okay, lets start coding. :)
I was wondering if I could use the hardware interrups in a 16F877A to ckeck the status of the USART receiver, and the status of some buttons (on portB change). I looked in the manual, and there seems to be two commands:
ON INTERRUPT and ON_INTERRUPT. The one that does it on software is really wasteful of memory, and makes the whole code run much slower, so how can I configure the other interrupts??? I would really appreciate it if you could give me some code examples. Thanks in advance, Manuel.
