| Problem with 18F45K22 RS232 Configuration |

Hi, i have problem with this pic... Not work the RS232 by Hardware.
The port by Software if work :/
Someone know what configuration should I do.?
| Code: | #include <18LF45K22.h>
#device ADC=10
#FUSES NOWDT //No Watch Dog Timer
#FUSES NOBROWNOUT //No brownout reset
#FUSES NOLVP //No low voltage prgming, B3(PIC16) or B5(PIC18) used for I/O
#FUSES NOPBADEN //PORTB pins are configured as digital I/O on RESET
#FUSES NOMCLR //Master Clear pin disabled
#use delay(crystal=12MHz)
#use STANDARD_IO( A,B,C,D,E )
#use rs232(baud=9600,bits=8,parity=N,xmit=PIN_C0,rcv=PIN_C1,ERRORS,stream=debug) // Configuración debug (Software)
#use rs232(baud=9600,bits=8,parity=N,xmit=PIN_C6,rcv=PIN_C7,ERRORS,stream=uart1) // Configuración UART1 (Hardware)
#use rs232(baud=9600,bits=8,parity=N,xmit=PIN_D6,rcv=PIN_D7,ERRORS,stream=uart2) // Configuración UART2 (Hardware)
#define LED PIN_C2
#define DELAY 1000
void main(){
setup_timer_0(T0_OFF);
setup_timer_1(T1_INTERNAL|T1_DIV_BY_8); // 174 ms overflow, Setup timer: Reloj interno, preescaler= 8
set_timer1 (0xE4D); // Carga del TMR1 0.165=4/12000000*8(65536-x),x=3661 >> Tiempo de desbordamiento es 0.165 segundos
setup_timer_2(T2_DISABLED,0,1);
setup_timer_3(T3_DISABLED|T3_DIV_BY_1);
setup_timer_4(T4_DISABLED,0,1);
setup_comparator(NC_NC_NC_NC);
setup_ccp1(CCP_OFF);
setup_ccp2(CCP_OFF);
setup_ccp3(CCP_OFF);
setup_ccp4(CCP_OFF);
setup_ccp5(CCP_OFF);
setup_dac(DAC_OFF);
setup_adc(ADC_OFF | NO_ANALOGS);
setup_adc_ports(NO_ANALOGS|VSS_VDD);
setup_wdt(WDT_OFF);
fprintf(uart1,"Hola mundo");
fprintf(uart2,"Hola mundo");
fprintf(debug,"Hola mundo");
while(TRUE)
{
//Example blinking LED program
output_low(LED);
delay_ms(DELAY);
output_high(LED);
delay_ms(DELAY);
//TODO: User Code
}

First thing I see is that you are using reserved words for the stream names.
Try using something besides UART1 and UART2 like U1 and U2
Try this: (default is 9600/N/8/1)
#use rs232(UART1,ERRORS,stream=U1) // Configuración UART1 (Hardware)
#use rs232(UART2,ERRORS,stream=U2) // Configuración UART2 (Hardware)

I alway use this configuration for others pic, and i have not problem...
i changed this, but still not work... I think the problem is C6,C7 and D6,D7 this pins need some configurations. :/
Thanks you. |
