PICAXE Send NEC Codes Using PWM

I am trying to send some NEC transmission codes to control my colour changing bulb using a PICAXE. The microcontroller I use is not too important right now, but I will need LCD's and RTC modules later on.

I have read some of the IR documentation on the PICAXE manual, however, it only uses the SIRC protocol, which will not work.

I believe I need to use a pwm pin connected to an ir led to generate this. However, I am not sure how to do this - or even if this is possible.

Side note: I am also confused as to how I can generate the 38khz carrier frequency as well.

Thank you so much for the help.
