| RS232 using MPLAB UART1 |

Hi Folks,
I am new to this compiler and have a question about using UART1 to simulate input. It works fine in ASM but a simular C version hanges on the getc() and does not take the input from the text file. My progam is very simple | Code: | #include <18F4550.h>
#ignore_warnings NONE // report all warnings
#define CLOCK_48MHz // micro clock frequency
#include <stdlib.h>
#include <STRING>
#include <CTYPE>
#include <STDDEF>
#use delay(clock=48000000)
#use rs232(baud=9600,xmit=PIN_C6,rcv=PIN_C7,bits=8,parity=n)
void main()
{
int8 x=0x55;
while(1)
{
putc(x);
x=getc();
}
}
|
Does this mplab feature work with the compiler or is there a problem with the code snippet.
PS the unital 'U' character is displayed in the display box.
Regards
Robert. |

The text file that you give to UART1 has to have the text in quotes.
Example:
| Quote: | | "ABCDEFGHIJKLMNOPQRSTUVWXYZ" |
