PWMOUT frequency

[jsimpson001]

does anyone know how to set pwmout to a freq of 38khz, ive already had a go but it doesn't seem to work (the project is an IR beam alarm, and the IR LED is being modulated.

Heres the code
<code><pre><font size=2 face='Courier'>
'INFRARED BEAM ALARM FOR PICAXE-08M

symbol detector = pin3
symbol stateval = b0

init:
low 1
let stateval = 0
pwmout 2,38,19
wait 2
goto detect

detect:
if detector = 1 then sendback
if detector = 0 then valset
goto init

valset:
let stateval = 1
goto action

action:
if stateval = 1 then alarm
if stateval = 0 then init
goto init

alarm:
high 1
goto sendback

sendback:
if detector = 1 then detect
if stateval = 1 then alarm
</font></pre></code>

According to my PWM wizard, 38kHz @ 50% duty is PWMOUT pin, 25, 53.

The PWM wizard is in the program editor, look in PICAXE/wizards/pwmout
