Hi,
i found that two interrupts(USART and RB0) are working and when i turn on micro it goes to interrupt routine.
for RB0 i should connect a pull up resistor but when i connect the out put of the RF reciever to it interrupt occurs.
i don't know why?
maby the noise of RF reciever (when we don't have data) is the reason.
for USART interrupt ,i have the same problem but in this case , there is no deference between connecting and not connecting the RF reciever.
when i turn on micro it goes to interrupt routine.
what is the reason?
what should i do?
