Hi, I need some help regarding the UART feature in 16F877. I need to send a byte of data over the serial port to the PC(just for the sake of implementing UART). I am using a 11.0592 MHz crystal oscillator. 1. DO I need to use a MAX232 driver or can I directly connect to the serial port(DB 9) pins(TX and RX). 2. I have a windows PC. How can I read the serial port ? I mean if I send the data from the PIC, how can I know what data I am receiving etc. Are there any programs or s/w ?
