DTMF coder

[Constantin_Ivl]

I have a problem. I have some program, which generate DTMF signal with the determinate parameters. I can`t set the determinate duration of the signal. There is keypad number set, but it should be hand-set. For example "3" "4" "2" . I mean, the signal of this numbers, which were fixed before, arise after the key START pushing. The signal (dual tone)  should come out of each number with the  definite (variable) duration, and definite (variable) interval between them.

Perhaps it is a language barrier, but I don't understand what you are asking for.  Your VI seems to behave the way I'd expect it to if it was a telephone keypad, other than the fact the tones seem to have a bit of "warble" to them.
