Internal osc ckl out

[Edward LaBudde]

Hi all, newbie here.  Was checking the clk out config.  With this code a 12F675 works ok  Here is the code:

'An external osc output
'Tested 02-19-09 works

'Chip model
#chip 12F675, 4
#config osc = INTRC_OSC_CLKOUT

dir gpio.4 out 'Pin 3
dir gpio.5 out 'pin 2

start:
set gpio.5 on
wait 100 us
set gpio.5 off
wait 100 us
goto start

Tried the 16F88 it does not work!  with this code:
'An external osc output
'Tested 02-19-09 does not work!

'Chip model
#chip 16F88, 8
#config osc = INTRC_CLKOUT

dir portA.6 out 'Pin 15
dir portA.0 out 'pin 17

start:
set portA.0 on
wait 100 us
set portA.0 off
wait 100 us
goto start

I checked the chip data an all appears well

here is what the .asm says:
__CONFIG _CONFIG1, _INTRC_IO & _WDT_OFF & _LVP_OFF & _MCLR_OFF

it should say?: INTRC_CLKOUT

It does not look like it set the clock out!

What am I doing wrong?, Regards, Ed.

Hi Ed.

I think you are right: _INTRC_IO is internal clock NO clockout , it should say INTRC_CLKOUT

But this way works ok for me: #config INTRC_CLKOUT

Kent thanks again.  You are correct as usual!  It does not like
#config osc = INTRC_CLKOUT,

it likes yours #config INTRC_CLKOUT

There were no warnings of course.
