Don't know what's wrong!

loop:
high portb.0
pause 500
low portb.0
pause 500
goto loop

try that.

Hello PICante,
The 628A has analog comparator inputs, so unless you are using them turn them off with
CMCON = 7
then read the post on config fuses
try:

@ DEVICE pic16F628A, HS_OSC ' Change HS to XT for 4mhz

@ DEVICE pic16F628A, WDT_ON
' Watchdog Timer

@ DEVICE pic16F628A, PWRT_ON
' Power-On Timer

@ DEVICE pic16F628A, MCLR_ON 
' Master Clear Options (Internal)

@ DEVICE pic16F628A, BOD_OFF
' Brown-Out Detect

@ DEVICE pic16F628A, LVP_OFF
' Low-Voltage Programming

@ DEVICE pic16F628A, CPD_OFF
' Data Memory Code Protect
' Set to CPD_OFF for Development Copy
' Set to CPD_ON for Release Copy

@ DEVICE pic16F628A, PROTECT_OFF

DEFINE OSC 20 ' for 20 mhz, change to fit your OSC speed

that code should setup your configs if using the default compiler, MAPSM uses different configs.

Hello PICante,
The 628A has analog comparator inputs, so unless you are using them turn them off with
CMCON = 7

But not on PortB.0...(that was my first thought too).
Everything else still applies in full...if not more...

Thanks all of you!

I have some reading to do (obviously) and I get back on this matter if I don’t figure it out myself!
One 180 page datasheet and then some … phuuuu.

Thanks again :-)

Merry Christmas!

Stop whining

I am looking at the data sheet for the 18F4550 over the holiday.

428 pages!

Merry Christmas to you too.
