16F914 and MPASM

[jderson]

Thank you, Bruce. I just tried it again with the following line:

__config_DEBUG_OFF_FCMEN_OFF_IESO_OFF_BOD_OFF_CPD_ OFF_MCLRE_OFF_PWRTE_ON_WDT_OFF_INTRC_OSC_NOCLKOUT

It made no difference. Compiles in MPASM with no errors, but will not run:

__config_DEBUG_OFF_FCMEN_OFF_IESO_OFF_BOD_OFF_CPD_ OFF_MCLRE_OFF_PWRTE_ON_WDT_OFF_INTRC_OSC_NOCLKOUT
OPTION_REG = %11000000
INTCON = 0
PIE1 = 0
PIE2 = 0
ANSEL = 0
TRISA = %00000000
TRISB = %00100001
TRISC = %00000000
TRISD = %00000000
TRISE = %1000
OSCCON = %00000001
CMCON0 = 7
ADCON0 = 0
WDTCON = 0

SSPCON = 0
CCP1CON = 0
CCP2CON = 0

CLEAR

LCDPS = %00110000
LCDCON = 0
LCDSE0 = 0
LCDSE1 = 0
LCDSE2 = 0

PORTA.7 = 1
LED1 VAR PORTA.7

Main:

PORTA.7 = 1
pause 10
PORTA.7 = 0
pause 10
goto Main

Any other suggestions?

It shouldn't compile the way you did it... seems odd syntaxe.

How about

@CFG1 = _DEBUG_OFF & _FCMEN_OFF & _IESO_OFF & _BOD_OFF & _CPD_OFF
@CFG2 = _MCLRE_OFF & _PWRTE_ON & _WDT_OFF & _INTRC_OSC_NOCLKOUT
@   __CONFIG CFG1 & CFG2

If you really got this to compile as-is, you definitely have something VERY strange
going on.

That config line is really a mess. Try the attached and let me know if it works.

Problem finally solved! The config settings were the problem. Thank you, Bruce, your code worked. Thanks also to Charles Leo at MeLabs. You both solved the problem at the same time! Will I ever learn?
