Hello, i've been lurking in the backgrounds, picking up what I need to program a Pronto TSU2000 remote, and am almost complete.
The last device I'm trying to code is a NEC LT240K projector, which when it is powered on requires 2 seconds of the on button being held down.
I've done some searches, and came across the IR tutorial, and tried diagnosing the IR code.
I'm trying to isolate what I need to do to get a macro to have the on button seem to be on for the 2-3 seconds needed to power on the projector..
As a secondary purpose, I wanted to learn how to clean up the IR code to be a "clean" code, if possible.

Anyways, if anyone could take a look at this, I'd appreciate it!

006d-frequency of ir carrier formula: Frequency (kHz) = 1000000 / (N * .241246)
where N = decimal value of second hex code (in this case dec[6D] = 109)
so frequency = 38028.87 kHz. Freq has a tolerance of +- 10% so roughly a 40000 kHz cycle.

0016 0e3e


Okay, now is it just the 0016 0e3e that needs to be repeated? am I missing something here?

So i create a button with the repeatable code, and alias it, how many times?

also, the NEC codes are supposed to be 34 bits divided into 4 strings of 8 bits (say A, B, C, and D)
A & B are supposed to be compliments but they aren't in the code learned above (dirty code?)
C & D seem to be compliments of each other no questions here

and finally, how would one clean this up? or is it "good enough"?

Sorry for the length, I've tried going as far as I can, and just need a little push... :)

I believe this is the NEC protocol where the second 8 bits are the Sub Device code. When you hold down the button of the above code the 0154 0055 0016 0e3e is the part that repeats. In terms of clean it's not bad and should work fine, I would suggest it is easier to generate clean codes via Make Hex etc. than to clean dirty ones, but others may disagree. I remember previous threads on the best way to accomplish the 2 second button press so try a search.

Cool, I was just missing the 0154 0055. I created a new button with the 4 hex #'s, aliased them about 10 times, and it worked.

Only bad thing,
right after i tested this, the screen decided to die?
I still have a backlight, and can hear the buttons being pressed, but can't see anything...
I'm hoping it's just the screen, (I've seen the tutorials on replacing those...) ARG!
Tried reflashing, and am going to leave it w/o batteries overnight tonight... sigh
just when everything is going well...

Do you have the finished code that you could post. Would be a great help as I cannot get my remote to learn the codes.

Thanks

Yeah, I'll post the on / off codes tonight. If you are trying to setup a button to power it on / off without having to hold down the button (like I am), the repeat code, which is listed above (0154 0055 0016 0e3e) needs to be aliased about 4 times for the on, and about 5 for the off after the on off codes.

This is the NEC 240K on code (should also work for the 260)
0000 006d 0022 0002 0154 00aa 0016 0014 0016 0014 0016 0014 0016 003e 0016 003e 0016 0014 0016 0014 0016 0014 0016 003f 0016 0014 0016 0014 0016 003e 0016 0014 0016 003f 0016 003e 0016 003e 0016 0014 0016 0014 0016 0014 0016 003e 0016 0014 0016 0014 0016 0014 0016 0014 0016 003e 0016 003e 0016 003e 0016 0014 0016 003e 0016 003e 0016 003e 0016 003e 0016 0618 0154 0055 0016 0e3e

and the off (uses the same repeat)
0000 006d 0022 0002 0154 00aa 0016 0014 0016 0014 0016 0014 0016 003e 0016 003e 0016 0014 0016 0014 0016 0014 0016 003e 0016 0014 0016 0014 0016 003f 0016 0014 0016 003e 0016 003f 0016 003e 0016 0014 0016 0014 0016 003e 0016 0014 0016 003e 0016 0014 0016 0014 0016 0014 0016 003f 0016 003e 0016 0014 0016 003f 0016 0014 0016 003e 0016 003e 0016 003e 0016 0618 0154 0055 0016 0e3e

And finally,
Removing the batteries from the pronto for a day seemed to fix the screen issue. Now, baring any future found bugs, the programming is done! Thanks for the help!
