the problem of my code.

[Lion]

Hello,

I am using PIC16f877.

I got two problem.
First of all. the compiler told me that "Line 3(5,47): Baud rate out of range" but I think that the baud rate 9600 is not out of the range. Am I right?

My code is following:

__________________________________________________

#include <16F877.h>
#use delay(clock=100000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)
#define BUFFER_SIZE 18

void main()

{
char szAddr[BUFFER_SIZE];
int nBytesRead;


puts("get address\r");
delay_ms(1);
printf("the device address is %S", szAddr);
}

______________________________________________________

The second problem:

I am trying to send a string to my wireless device by TX but I do not know how to control it. I mean that I need to send a command which is only for the wireless device to control it to make this device to connect to another one. How can I know that this command has already sent to TX? Do I need point out the specific PIN such as PIN_C6?

I am really really new on the C and Microcontroller.

Any help will be really appreciated!



Thank you very much.



Sincerely,



Brian

The compiler is right. You said the clock is 100,000. That is very slow. The clock is used to generate the baudrate. So 9600 baud would be OK if you are using a much higher clock.

Hello RLScott,

It works now. Thank you for your reply.
The first problem is solved.
Does anyone have suggestion for second problem?
Any help is appreciated.
Thank you very much.
Sincerely,

As written any serial output will go to pin C6. Is this what you want? Do you have one serial stream to a terminal and another to the wireless? If so you need to use "streams" with your #use RS232 statements.

It would help if you told us what wireless device you was using.

Hello,

Thank you guys' kindness.

I am using PIC16f877 and MPLAB v8.10 with CCS.

I try to use PIC16f877 (PIC A) to control a bluetooth by USART and to communicate with another PIC (PIC B )which also has a bluetooth device on it.

My question is that I need to send some command to bluetooth such as "get address" which is to get the address of bluetooth or "con 00:8A:16:7C:89:7L" which is a command to connect to the other bluetooth.
I do not know how to send the string to bluetooth TX (PIN_C6) in PIC A or get a string from RX(PIN_C7) in PIC B.

I am really really new on C and PIC so could you tell me how to do that?

By the way, I knew the basic concept of stream but I have no idea how to use it with USART or how to write a code with it.
Could you guys kindly explain to me or give me some example to understand how to use it?

Any help will be really really appreciate.
Thank you very much.
Sincerely,
Brian
