Serin serout problem

[lerameur]

yes it does oscillate
when I put thisline:

@ DEVICE PIC16F876A , HS_OSC , WDT_OFF , PWRT_ON , BOD_ON , LVP_OFF , PROTECT_OFF

and not:
DEFINE OSC 20

led on RC3,.. do not work

@ DEVICE PIC16F876A , HS_OSC , WDT_OFF , PWRT_ON , BOD_ON , LVP_OFF , PROTECT_OFF

TRISC =0

Pause 1000 ' Wait 1 second

loop:

lcdout $FE,1, "Number: ", dec 55
pause 100

portc.3=0
portc.3=1
pause 300
portc.3=0

goto loop

end

even this do not work...
compiles and everything, but no action

DEFINE OSC 20 is for PBP and it's internal compiler and setting up various timing loops; it doesn't set any config bits anywhere in the PIC.

Leave both in there.

then why doesn't the program in post 242 work ??

osc running at ~20mhz?
are you using a crystal or one of those can oscillators?
all other things being equal, it's probably the programmer's fault (not you, I mean the actual hardware)

[lerameur]

i am using a crystal 20.0Mhz
programmer ? I have another one ...

ok TRied the easy Prog Programmer,
http://www.embedinc.com/easyprog/index.htm
does not work more, same thing, I meam .. nothing is happening...

Just curious, is the chip a 16F876 or a 16F876A.... there's a difference as far as programming method goes...
