Manual says IRSEND, but I get an invalid command error to that.
IR SEND seems more happy, but I still get a "Variable name" error. �

What am I doing wrong?

EDIT: Do "dev" and "key" as per the manual page 26, have to be variables?
I would have thought you could just insert actual integer values here, but perhaps I am wrong....

Don't know which version you are using but 25046 is invalid. Should be between 0 and 31

25046 is what was reported by the examine code in the manual:

Oh, BTW, Micromite2 firmware 5.0408

Perhaps I need to update if there is a newer version?

IR SEND uses the sony 12-bit code. 5-bits for the dev (0-31) and 7 for the key (0-127). Receive can also receive NEC codes

For codes other than Sony you will need to find the specifications and use Bitbang Bitstream.

UPDATE:

The NEC code Csub works a charm to control my LED projector.
The old remote-control is wearing out, and I often have to press the buttons VERY hard to get things to work, but cos it was a projector out of eBay several years ago, I cannot find replacement remote controls for it.

Using a MicroMite solves this problem completely, and now I can built a wee box of tricks that with one button press, will turn the projector on and set it to the input I want etc, and then another button can turn it off.

Thanks to matherp, for writing the NECSend Csub, without which, I would not be able to do this.
