PIC24F16K101 UART Problem
PostPosted: Fri May 20, 2011 3:52 am     Reply with quote
Hello ...

I have a problem with the PIC24F16K101.
UART1 Pin11 and PIN6 is connected to a MAX232, the electronic functions are perfect, at pin 6 of the pic comes to the character from the terminal.

But the pic does not respond with the following code.
He run up to getc and stays there.

In the other direction, that's very good,
characters sent by the controller com on in the terminal program.

Code:

#include <main.h>
#include <stdlib.h>
#include "stdio.h"

char c0, c1, c2, c3, c4, c5, c6, c7, c8, c9, d0;

#INT_RDA


void main()
{
setup_adc_ports(ALL_ANALOG,VSS_VDD ); 
setup_adc(ADC_CLOCK_DIV_4|ADC_TAD_MUL_8);


enable_interrupts(intr_global);


output_bit(pin_b13,1);
output_bit(pin_b15,1);
   
while(1)
{

#use rs232(uart1,baud=9600,parity=N,xmit=PIN_B7,rcv=PIN_B2,bits=8)

c1 = getc();

printf("%c",c1);

output_bit(pin_b13,0);delay_ms(250);output_bit(pin_b13,1);delay_ms(250);
}
}

You have #int_rda without any interrupt code.

Thanks for the answer....,it is right #int rda has nothing to do there

But is not the problem.....

The same code (without #int rda) works on a PIC24FJ128GA010 properly

Hello ....

the problem is solved....

my extra RS232 PCI card for 2 additional RS232Ports has received but not sent correctly

to the internal com port it works well

greetings ...
