problem with sending data to PIC18F2550 through RS232

[stoyanoff]

Hi, everyone! I made a simple pcb with PIC18F2550 and MAX232. Here is the hardware: https://dox.bg/files/dw?a=3b528d5ba9
So the controller works fine. It recieves data from the line(I`m using PC for transmitter). But when I tried to send data from the microcontroller it doesn`t send anything. Here is my code:

#include <18F2550.h> 
#fuses HS, CPUDIV1, NOVREGEN, NOPBADEN, NOWDT 
#use delay(clock=20M) 
#USE RS232 (baud=9600, xmit=PIN_C6,rcv=PIN_C7,BITS=8,PARITY=N,ERRORS) 

void main() 
{  
   while(1) 
   { 
      putc(5); 
   } 
}

It just blocks any the debugger can`t pass the #use RS232 line... I remove the MAX232 but again even without anything connected to it`s pins the microcontroller blocks there and it doesn`t transmit anything.
Do you have any idea what`s going on here??
Thanks!

Instead of linr putc(5)

Try this

putc('5')


And give some delay after that.

And i think with that

#use rs232 line you are usibg software uart try to use internal uart

i am not sure about syntax but ut is likr this

#use rs232(uart1,9600 like that
see ccs manual

- - - Updated - - -

Use this
//RS232 Configuration
#use rs232(baud=9600, UART1, errors)

and dont forget single quotes and delay

- - - Updated - - -

//RS232 Configuration
#use rs232(baud=9600, UART1, errors)

ise this and dont foget quotationd and delay
