As long as you aren’t faster than 40 ms between presses, you’ll datsheet the second press. Duane Benson 1 4. May I know how to transfer the data from pins: Started by fastline Yesterday at 8: Then connect the DSO pin 15 to a digital input with an interrupt-on-change and process when it goes high.


Incidentally, another approach would be to simply feed audio into the USB port using an off-the-shelf product, and then have the computer perform the DTMF recognition. I can’t definitively tell by the data sheet if the KT output would change if you pressed a second key while the first one is still pressed, but I’d guess that the fist output would stay latched unless you fully released the first key prior to the second press.

That is if I press a button say 1 darasheet immediately within the same second if I press key 2 Will it be able to recieve and decode the DTMF correctly with proper time synchronization? Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at If you press one key and then quickly press the next, you should be okay and get the second keypress as the maximum interdigit pause time is 40 ms.

This will be my first try at USB intefacing! Kt31770 you get the interrupt, read the Q1 – Q4 data, do whatever pre-processing you may want and send it out the USB port. My phone-set have no caller id facility. If I’m reading your data sheet right, it ignores such impossible-to-decode signals, and during such times acts the same as when it hears nothing but silence.
