hello.,
i need tutorial for Serial UART using interrupt and C18 Compiler.
please provide me link to understand this..
Thanks..

If you know how to use interrupt then its simple to use any peripheral with interrupt. In c18 there are only two vector locations (high and low priority) unlike 8051 where you have vector for each interrupt. By defult all interrupts are high priority, So you only have one isr for all. In ISR you check for interrupt flag and do work for whichever flag is set.
I am really not sure if there are tutorial out there that explains you regarding interrupt programming in c18. I suggest try google it once, you will find some examples.

what its mean by serial uart??kingrosekhan123
Seriously ?
Try this link
http://en.wikipedia.org/wiki/Universal_asynchronous_receiver/transmitter
Then google for details of how the Uart/ Usart built into PICs works.

UART is a serial protocol. I think try to understand the topology of serial and parallel interfaces first. It might help you understand basics.
