Both modes produce the same basic tone pairs for digital dialing, corresponding to the keys: These are stress fatasheet only. I have these working so on to my next problem. Ht9200n Guys, I just received my Arduino in the post a few days ago and have been having great fun with it. I don’t think this is the ideal IC for your purpose, because it’s set up to receive inputs from a key numeric pad.

For the most up-to-date information, please visit our web site at http: The relationship between the digital codes and the tone output frequency is shown in Table 1.

As for the control timing diagram, refer to Figure 1. As this information may be updated at regular intervals users are reminded to consult the Holtek website for the latest version of the package information.

Thanks in advance for any help. The information appearing in this Data Sheet is believed to be accurate at the time of publication. Every datasheeet of a phone number to be transmitted is selected by a series of inputs which consist of 5-bit data.

Read times previous topic – next topic. Thanks for any insight.

I promise to post start a build log for my alarm as soon as I know I can do it Still no tutorials however. As for the control timing diagram, see Figure 2. Then the input data codes should be determined. I think the serial interface would suit perfectly with the arduino but I may be wrong. To get it to work, you’ll have to get the arduino to mimic the electrical behavior caused by the capacitance change that happens when you press one of those buttons.

I’d really appreciate your help on this. Here is some code I wrote for that chip.

Would I just connect the data pin of the IC to the pin 1 of my arduino to send the serial data to it? Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.

When the IC is operating in the parallel mode, these pins become floating. When the IC is operating in the serial mode, this pin becomes floating. I am currently building a dstasheet alarm with 2 PIR sensors from sparkfun. X Y Pad No. I think what you want is an IC that takes something the arduino can talk to easily, like daatsheet, i2c, etc. Ah, I took another look at the datasheet and you’re right.

I know I’ve seen threads from other people trying to interface Arduino to DTMF, maybe there’s a solution out there that you could adapt. He recommends Holtek B. However, Holtek assumes no responsibility arising from the use of the specifications described. Thus, these data input pins should not float. The oscillator function can be implemented by Connect a standard 3.

Additional supplementary jt9200b with regard to packaging is listed below. I have searched the internet far and wide for the past few days and I have come up blank. Actually, I think it may be a little complex to use serial mode after viewing this document. The relationship between the digital codes and the tone output frequency is illustrated in Table 2. It has a serial and a paralell interface. Dimensions in mm Min.

I’m probably doing everything wrong as I am more of a programmer than electronic eng.
