PIC16F876-A problem with bootloader

mikroc usart_write examples

I m using PIC16F876-A....i hv copied the following program given in mikro C examples for bootloader....bt i hv been facing difficulty in building it....

void main()
org 0x1E7D
{

Susart_Init(129); //20MHz crystal

if (Susart_Write_Loop('g', 'r') != 255)
Start_Bootload();
else
Start_Program();
}


Someone please explain this program to me....as the instruction "Susart" is not given in help topics.....!!!!!!!!!!!!!

usart_write

Here you are the description

Prototype: void Usart_Write(unsigned short data);
Returns: Nothing.
Description: Function transmits a byte (data) via USART.
Requires: USART HW module must be initialized and communication established before using this function. See Usart_Init.
Example: int chunk = 0x1E;
Usart_Write(chunk); /* send chunk via USART */

This is from the help of the MikroC, there's nothing called "Susart". It's just "Usart".

I hope this helps.

Re: PIC16F876-A problem

thanx for your concern......bt i hv read about USART....and i hv used it for serial communication.....this problem is different from that...i think so..!!!!!!!!!

I hv used similar example for PIC18F252 and it was build successfully.....bt a different kind of problem occurred....for which i hv put a query at following link....
