How to PIC 16F887 connected with Xbee X24 by RS232 to PC

[kudo99]

Hi , I'm A , from Thailand and I'm new in coding microcontroller

I have problem with my project. I want to connect microcontroller from PC to PIC by Xbee.
My Xbee base is connected with PC by USB ( I use PDG-U Serial Converter to USB ) , my remote Xbee is connected with PIC
by RS-232 connect to RC7(RxD) ( My board microcontroller has slot and named it completely )

now I have no idea to make my project successfully , I have read older forum that use Usart library but it's still doesn't work.

Please help me

Best Regards

A

Hi!

Please, visit the links below:

http://www.mikroe.com/eng/products/view ... ee3-board/
There, you'll find information about connecting mikroElektronika's EasyBee boards and also demo examples written in our compilers.
I'm sure that this will help you get started with your project.

thank you very much Salavisa ,, I love your webboard 'coz make me know a lot of information about PIC and MikroC

Hi , I can't fix my problem now .. data is not collect from usart Rx that I sent to from PC serial port !

please help , I'm sick of it now and so tried ;(

Code: Select all

//#include<adc.h>
int c_switch = 0 , c_o2 = 0 ;
int pause = 40000 ;
int count = 0 ;
unsigned char * data ;
unsigned char receive ;
unsigned short i = 0;


void interrupt(){
char temp ;
while(!Usart_Data_Ready()) ;
i = 0;

do{
temp = Usart_Read();
PIR1.RCIF=0;
data[i] = temp ;
i++;
}while(!Usart_Data_Ready());


} // end void
