problem with switch case statements
PostPosted: Mon Feb 03, 2014 9:19 pm     Reply with quote
Hi everybody.. Im trying to do a switch case statement but the compiler throws an error...

*** Error 117 "probando_uart.c" Line 142(1,2): Improper use of a function identifier
*** Error 51 "probando_uart.c" Line 144(1,5): A numeric expression must appear here
*** Error 51 "probando_uart.c" Line 167(1,5): A numeric expression must appear here


this is my code
Code:

#include <16F877A.h>

#define LED_ON(x) output_high(x)
#define LED_OFF(x) output_low(x)
#define ledR PIN_B1
#define ledV PIN_B0

 }




im working with Xbee modules.. the problem appears when i try to compare the variable RUTA with a switch case...

RUTA is a byte
the cases would be EDR11, EDR12, EDR13..... these are bytes too.

Any help??
Thanks

Look carefully at this function. You're missing a brace.
