what is wrong with my code

[bloke203]

I am trying to send and receive data using PIC16F877, MAX232 and Hyperterminal. Can you suggest me the soultion of it?

void main( )

{
unsigned short i;
PORTA = 0;
PORTC = 0;
PORTB = 0;
TRISA = 0X01;
TRISB = 0X0;
TRISC = 0X80;


// Initialize USART module (8 bit, 2400 baud rate, no parity bit..)
Usart_Init(9600);

do {

TXSTA.SPEN =1;
if (Usart_Data_Ready()) { // If data is received
i = Usart_Read(); // Read the received data
PORTB = 0X04;
// delay_us(150);
Usart_Write(i); // Send data via USART

PORTA = 0X01;
}
}while (1);


}


// I am using mikro C compiler.

Anykind of help will be appreciated

Thanks

Regards

Your question is not proper.

1. No defination for Usart_Read() & Usart_init().
2. Are you using this function externaly? No header file included.

Thanks for the reply.

But Usart_read and other bits are coming from mikro C library itself. I am trying to send a character through Hypt terminal and want to receive the same data back to my Hyper terminal.

My program compile fines. It compiles fine. It doesn't give any error. When I dwnld its hex file into my PIC16F877 then it doesn't give me any character back to my hyper terminal.

Pls help me
