Hi, it is the first time I am trying to run a simulation of my ADC code in proteus, but I am facing a problem - I cannot even blink an LED currently. Following is my code to blink an led:



Include "modedefs.bas"
DEFINE OSC 4 ' OSCCON defaults to 4MHz on reset
DEFINE OSCCAL_1K 1

@ __Config _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_ON & _MCLRE_OFF & _BODEN & _CP & _CPD

pause 50
VALUE VAR WORD
PORTA=0
PORTC=0
TRISA = %001000
TRISC = %001000
CMCON = 7
ANSEL=%10000000
ADCON0=%1011100
ADCON1=%01010000
ANSEL = 0
OPTION_REG = %10001111

SWITCH_ON VAR ADCON0.0
START VAR ADCON0.1
CHECK VAR PIR1.6

START1:

WHILE 1
TOGGLE PORTC.5
PAUSE 100
WEND
GOTO START1

I have also attached a screenshot of my proteus connections. Once I get this corrected, I will run a simulation of battery monitor using ADC. Thanks

Another screenshot at the time of simulation. Can someone please tell me what are these blue and red dots appearing in when I simutlate? Thanks

Try connecting pin 4 (MCLR) of the pic to the regulator output V+.

Hi Mark, I have tried connecting MCLR to power via 10K. Problem is still there. But I think MCLR should not affect the operation as it is Off.

Hi, here is the DSN file. I had to make it a zip file as otherwise it does not appear in the 'select attachment' window.

Hi Darrel, it is really interesting that the code is running on your system.

Could it be that I have loaded the hex file or some other setting wrongly? I have attached the screenshot of the EDIT COMPONENT. I even tried it with the config word to be '0x3E4C' but no luck.

The only difference was that I put the code in the same folder as the .dsn file.
But that shouldn't matter.

Are you running the latest version of proteus?
I zipped the folder and attached it. Give it a try.

Hi

Runs fine on v 7.6 SP 4 Pro here ...

no special trick to use.
