CCS C Help!!!

[Wilksey]

Hi guys,

I have compiled a program in HITECH C which uses a software bit banged serial routine on a 16F887. All works fine, same board, same level shifts etc, but this time I created a simple program using CCS C V4.105 and the serial message is coming out with parity errors and incorrect data. Any help appreciated.
4MHZ internal clock btw.

Code below.
main.c

void main()
{
   setup_oscillator(OSC_4MHZ);
   setup_adc_ports(NO_ANALOGS);
   setup_adc(ADC_CLOCK_DIV_2);
   setup_spi(SPI_SS_DISABLED);
   setup_timer_0(RTCC_INTERNAL|RTCC_DIV_1);
   setup_timer_1(T1_DISABLED);
   setup_timer_2(T2_DISABLED,0,1);
   setup_ccp1(CCP_OFF);
   setup_comparator(NC_NC_NC_NC);
   setup_vref(FALSE);
   enable_interrupts(GLOBAL);

   while(1)
   {
      printf("1234");
      delay_ms(1000);
   }

}

main.h

#include <16F887.h>
#device adc=8

#FUSES NOWDT                    //No Watch Dog Timer
#FUSES INTRC_IO                   
#FUSES NOPUT                    //No Power Up Timer
#FUSES NOPROTECT                //Code not protected from reading
#FUSES NODEBUG                  //No Debug mode for ICD
#FUSES NOBROWNOUT               //No brownout reset
#FUSES NOLVP                    //No low voltage prgming, B3(PIC16) or B5(PIC18) used for I/O
#FUSES NOCPD                    //No EE protection
#FUSES NOWRT                    //Program memory not write protected
#FUSES RESERVED                 //Used to set the reserved FUSE bits

#use delay(clock=4000000)
#use rs232(baud=9600,xmit=PIN_A0,rcv=PIN_A1)

Ok, fixed it by putting this line below

enable_interrupts(GLOBAL);

:

set_tris_a(0b01000000);

Ooops!

Problem now is it is riddled with parity errors, i have changed the use code to:

#use rs232(baud=9600,xmit=PIN_A0,rcv=PIN_A1, parity=N,stream=pc)

Still doesn't want to play!

Any ideas?

Nevermind, found out the PSU was giving 5.10 volts, not 4.98 as it should!!
