I am trying to generate NEC1 codes with device 4 and I get the following for function 0.

0000 006D 0022 0002 0157 00AC 0015 0015 0015 0015 0015 0040 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0040 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0040 0015 0689 0157 0056 0015 0E94

I am simply dragging the included NEC1.irp file (that comes with Makehex) to the Makehex program. Why does it repeat twice without me specifying it to repeat?

The IRP file looks like this:

Device=4
Function=0..255

Protocol=NEC
Frequency=38000
Time Base=564
One=1,-3
Zero=1,-1
Prefix=16,-8
Suffix=1,-78
R-Prefix=16,-4
R-Suffix=1,-174
Default S=~D
Form=*,D:8,S:8,F:8,~F:8,_;*,_

Notice that there is nothing in there about repeating. What gives?

Looks right to me.


What do you mean by it repeats twice?

Is that something you see in the Pronto Hex that you think means repeat twice?

When you press the button on your Pronto, does the device do the action twice?





The parts of the IRP I quoted tell MakeHex how to contstruct the "repeat part" of the Pronto Hex. The repeat part of the Pronto Hex tells the Pronto what to do while the user holds the button down (assuming single action per button). If you hold the button long enough (or have some Pronto settings to make the Pronto act as if you had) the device MAY interpret that as repeating the command.

I wasn't clear on that from the readme that came with Makehex. I guess if I don't want any repeating, I would just insert the timing into the form syntax instead of defining R-Prefix, R-Suffix, Prefix, and Suffix. Is that the case?

The Prefix and R-Prefix lines define the '*' character used in the form. The Suffix and R-Suffix lines define the '_' character. In early versions of MakeHex that was the only way to get such timing into the form. Now you can put timing info directly in the form if you prefer that to using * and ;. But that choice isn't directly relevent to your stated goal of removing the repeat.

The ';' and everything following it on the form line describe the repeat. If you want a signal that can't repeat, remove the ; and everything after it. (for simpler protocols where the ; is the first character of the form, you would remove just the ; to make it non repeating).

If there is no ; then the R- lines will be ignored. You might then want to remove them just to reduce confusion.

Where can I find the Makehex program?
