Re: Please help!! receiving more than one character on PIC16

hi, sorry it took so long. here is the code im using.


#include <16F877.H>
#device ICD=TRUE
#fuses HS,NOLVP,NOWDT,PUT
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C7, rcv=PIN_C6)

void main(void)
{
char x;
x=" ";
while(1)
{
char x;
if (kbhit())
{
x = getc();
}
}
}
 

why do you define "char x;" twice? it should be just once...

I think the code works very well, it will read all the characters in "x" maybe you need to read two characters at time??? duh!

Code: 
void uart_gets(char *s)	// Get String from UART
	{
		
		while(((*s)=uart_getc())!=13)s++;//until last character is carriage return
		*s=0;
	}

enjoy!
