If you press one key and then quickly press the next, you kt317 be okay and get the second keypress as the maximum interdigit pause time is 40 ms. How to build a USB controller having knobs, sliders, and switches. Sign up using Facebook.
I don’t know what your transmit latency will be.

As long as you aren’t faster than 40 ms between presses, you’ll get the second press. You need to learn about the phone system in your country and it might be different in different parts of your country. 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. The way I interpret the data sheet, I would connect Q1 – Q4 to digital inputs on the microcontroller.
Click here to register now. Just saying hello Started by MichaelaJoy Yesterday at 6: Welcome to our site! 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.
If reading the decoded data from that DTMF signal is all you want to do, programming a microcontroller seems unnecessarily complicated.
Low Power Dtmf Receiver Semiconductor
May I know how to transfer the data from pins: Incidentally, another approach would be to simply feed audio into the USB port using an off-the-shelf product, and then it3170 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.
Many peoples obtained positive result by following the circuit in the above link using KT Articles Top Articles Search resources.
