The driver is probably already in your OS if you’re using recent Windows. If reading the decoded data from that DTMF signal is all you want to do, programming a microcontroller seems unnecessarily complicated. When you get the interrupt, read the Q1 – Q4 data, do whatever pre-processing you may want and send it out the USB port.

Then connect the DSO pin 15 to a digital input with an interrupt-on-change and process when it goes high. Post as a guest Name. Home Questions Tags Users Unanswered.

Replacing a 4 pin leaded inductor with a 2 pin Dxtasheet by gkmaia Yesterday at May I know how to transfer the data from pins: You must log in or register to reply here. Potentiometer Questions Started by norbss Yesterday at Duane Benson 1 4.
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 datasgeet DTMF recognition. There’s no way a DTMF chip could do that. If the computer sees something that starts out looking like a DTMF tone but the frequencies change after ms, it might be able to depending upon the application retroactively determine that the tones weren’t really DTMF after all.
My phone-set have no caller id facility. In the case of MT I have to design complex ring detection circuit to automatically off-hook.
How to build a USB controller having knobs, sliders, and switches. For example, a computer could take advantage of the fact that DTMF is generally gated on and off relatively cleanly. This will be my first try at USB intefacing!
