PIC18F4550 RS232 mplab ide

[clau]

Hello,

I'm using a PIC18F4550, MAX232 and MPLAB IDE.

I'm desesperate!! I want a simple example code.

Here's my "schematic" :

I just want a simple code in c so I can confirm that RS 232 is working!

PS- I'm using RCOM Serial

Best regards,

#use delay (clock=4000000)
#fuses HS,NOWDT,PUT,NOBROWNOUT,NOLVP
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, bits=8, parity=N)


void main ()
{
	
	printf("Hello World \r\n");
	output_high(pin_d1);
}
