TX9D: 9th bit of Transmit Data, can be Parity bit.

TRMT: Transmit Shift Register Status bit.

So now, letвЂ™s see how these registers can be configured. Here, TXSTA and RCSTA are the control registers. Register configurationД«efore moving on to program lets understand the registers associated with PIC16F877A UART. So the same value should be set in RealTerm. We will be configuring our UART to work on a Baud rate of 9600. Make sure you chose the right port and Baud rate in Realterm. we will use the serial terminal, вЂ RealTermвЂ™ for transmitting and receiving data from the computer side. This tutorial will focus on receiving a character typed on PC and then transmitting that back to PC to display on the screen. TTL вЂ“ RS232 converter circuit TTL вЂ“ USB converter circuit But if you want to build your own, use the below circuits. TTL вЂ“ RS232 or TTL USB converter modules can be easily purchased. Also, you may directly use a TTL to USB converter. If your PC doesnвЂ™t have a DB9 port, you might want to use an RS232 to USB converter. This can be achieved using a DB9 connector. which is a level translator that helps the PIC Microcontroller to connect with a PC using RS-232 telecommunications standard.

In this tutorial, we learn to Enable the inbuilt hardware module for UART in PIC16F877A Microcontroller and how to communicate with your Computer using the UART protocol.ДЇor this, we will use an IC called MAX232.

Serial communication using a Microcontroller is one of the easiest operations to learn on a microcontroller and it comes into use in almost every application. A universal asynchronous receiver-transmitter is a hardware module for asynchronous serial communication in which the data format and transmission speeds are configurable.
