| 2nd printf is never run in simulator? |

why does my program stop before the 2nd printf in the simulator?

| Code: | #include "C:\Documents and Settings\scott\Desktop\test.h"

#int_AD
AD_isr()

int1 i = 0;
void main()

port_b_pullups(TRUE);
setup_adc_ports(RA0_ANALOG);

i=1;
delay_ms(10);
output_high(PIN_B7);
delay_ms(1000);

printf("hi");
printf("BYE");
printf("2 BYE");
}

| This needs to be addressed to Microchip |

Josh,
You need to address all these questions about problems in MPLAB to the Microchip forum, not here..
CCS has on more then one occasion made it clear that they make no guarantees about supporting CCS C in MPLAB. Any interface CCS provides is a courtesy and CCS cannot be expected to provide support for a Microchip product especially a free one. They sell their own IDE and debugger that works very well with the CCS compiler. |

dyeatman is correct, you'll probably get a much better response in Microchip forums.
But as a general rule of thumb, never step into/over delay and RS232 statements. Either set a breakpoint on the next line after them and run the code, or go to the next line and right-click, then choose 'Run to here'. |

| I am asking about that because ccs does not have a simulator |

| Is that the whole program? No device? No #use rs232? No clock speed? Fuses? Look at the CCS example files to see how to setup a C file. |

| Ok The device information I used was created by the wizard. I will post it when I get home. I know the wizard does not put in NOWDT when you turn the box off so I was wondering if it left somehting nessisary out. |
