I can’t jt3170 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.

If reading the decoded data from that ,t3170 signal is all you want to do, programming a microcontroller seems unnecessarily complicated.

Sign up using Email and Password. The driver is probably already in your OS if you’re using recent Windows. This will be my first try at USB intefacing! I don’t know anything about the delay your FM modulator and demodulator will add to the system, but I suspect the total latency will still be well under 0. k3t170

If the computer datqsheet 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. For a better experience, please enable JavaScript in your browser before proceeding. You need xatasheet learn about the phone system in your country and it might be different in different parts of your country.

To participate you need to register. As long as you aren’t faster than 40 ms between presses, you’ll get the second press. If you press one key and then quickly press the next, you should be okay and dtasheet the second keypress as the maximum interdigit pause time is 40 ms. May I know how to transfer the data from pins: In the case of MT I have to design complex ring detection circuit to automatically off-hook.

Many peoples obtained positive result by following the circuit in the above link using KT For example, a computer could take advantage of the fact that DTMF is generally dataeheet on and off relatively cleanly.
