18F2550 Blinking LED With Pickit 2

[kiewic]

Thanks mackrackit, but unfortunately it doesn't work. I made the changes you recommended, but the PIC continues not working

How is the MCLR pin connected?

If it is not connected to anything then change the 3H line to

__CONFIG    _CONFIG3H, _PBADEN_OFF_3H & _MCLRE_OFF_3H

[mackrackit]

I just tested this on a 4550 (I do not have a 2550) and it works as expected.

DEFINE OSC 8
@ __CONFIG    _CONFIG1L, _PLLDIV_5_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_2_1L
@ __CONFIG    _CONFIG1H, _FOSC_INTOSCIO_EC_1H
@ __CONFIG    _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
@ __CONFIG    _CONFIG3H, _PBADEN_OFF_3H & _MCLRE_OFF_3H
@ __CONFIG    _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L & 0DFh
OSCCON = %01110000

    TRISD = %00000000
    TRISC = %00000000
    flip:
    HIGH PORTD.7
    PORTD.6 = 1             'Turn on LED
    PORTC.0 = 1
    PAUSE 500               'Delay for .5 seconds
    PORTD.6 = 0             'Turn off LED
    PORTC.0 = 0
    PAUSE 500
    GOTO flip

The MCLR pin is connected directly to the first pin of the Pickit 2.

I tried changing that configuration, but nothing happened.

[mackrackit]

Might be a stupid question but are you compiling for the correct chip?
Are you using MCS?

Yes, 18F2550 is selected on the combo box.

I'm using MicroCode Studio 3.0.0.5 and PICBASIC PRO 2.50B. When I compile, it uses the MPLAB assembler and it opens and closes a console window.
