DTMF generator

[JensG69]

It's kind of annoying to repeat the same answer over and over again. With an USB-6008, you can only use the DAQmx-Write-> 1 Sample selections. No waveform, no 2D-Array. With one channel just 1 numeric.

A USB-6211 on the other side is capable to run your programm from your first message...

Hi Gerdw,

         I've connected using usb 6211 and i can generate a DTMF tone and another thing is i have connected the output with the HT9170 DTMF receiver and i tested using that decode it gives exact signal what i want, now what i want is i need to auto generate a tone with some delay in ms, i have attached you a code so that you could understand and i have used time delay function to give a delay between each tone but it not affecting the output.

Thank you,

Regards,

Paul

Hi Paul,

i need to auto generate a tone with some delay in ms

What about a state machine approach? Or a queue-driven state machine?

It would be very easy to handle things like "automated state changes"!

(Easiest would be to use a FOR loop to dial an array of numbers…)
