Serial communication with Pic 16f877 using UART

Abstract of that project: Using UART port we can establish serial communication between any devices. Here in my project Serial communication with Pic 16f877 using UART I will show you how easily we establish communication between two devices. In my project we know the pin no 25,26 in PIC16F877 are use as UART. The pin number 25 is use for receiving and 26 is used for transmitting.

Hardware needed: See the circuit diagram bellow we use MAX232,UART port, Pic16f877 and LCd (Lm106L) to make our project.

For Simulation: we use Mikcro C pro to write the embedded C program for PIC16F877. We used Proteus 7 Professional for simulation. And for simulation of our project Serial communication with Pic 16f877 using UART, we replace COMPIM and MAX232 with Virtual UART Terminal.

So see our replace circuit for simulation in Proteus in bellow.

Mikcro C Pro Code:

To interfacing UART with Pic we have to use some new command those are

UART1_Init(Baudrate):is Initialize UART module at specified baudrate.

 UART1_Data_Ready() : use to check data is receive or not.

 UART1_Write_Text(“Start”): use to write declared text on uart

 UART1_Write(): use for transmit uart data.

 UART1_Read(): use for read the uart data.

 Now see at below the programing code to understand use of above mention command.
