The relationship between the digital codes and the tone output frequency is shown in Table 1. Then the input data codes should be determined. Below is a datasheet for my IC and I have spent many hours dtaasheet to get this to work The applications mentioned herein are used solely for the purpose of illustration and Holtek makes no warranty or representation that such applications will be suitable h9t200b further modification, nor recommends the use of its products for application that may present a risk to human life due to malfunction or otherwise.
Dimensions in mm Min. For the most up-to-date information, please visit our web site at http: As this information may be updated at regular intervals users are reminded to consult the Holtek website for the latest version datasgeet the package information. However, Holtek assumes no responsibility arising from the use of the specifications described. These are stress ratings only. As for the control timing diagram, refer to Figure 1. The relationship between the digital codes and the tone output frequency is illustrated in Table 2.
I am currently building a burglar hf9200b with 2 PIR sensors from sparkfun. Every digit of a phone number to be transmitted is selected by a series of inputs which consist of 5-bit data. 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 don’t think this is the ideal IC for your purpose, because it’s set up to receive inputs from a key numeric pad. Both modes produce the same basic tone pairs for digital dialing, corresponding to ht9200 keys: He recommends Holtek B.
When the IC is operating in the serial mode, this pin becomes floating. Here is some code I wrote for that chip. Ah, I took another look at the datasheet and ddatasheet right.
I know Ht9200 seen threads from other people trying to interface Arduino to DTMF, maybe there’s a solution out there that you could adapt. Actually, I think it may be a little complex to use serial mode after viewing this document. Thus, these data input pins should not float.
HT9200A/HT9200B — DTMF Generators
Still no tutorials however. I think the serial interface would suit perfectly with the arduino but I may be wrong. Thanks for any insight. As for the control timing diagram, see Figure 2. I promise to post start a build log for my alarm as soon as I know I can do it Thanks in advance for any help.
The oscillator function can be implemented by Connect a standard 3. I’m probably doing everything wrong as I am more of a programmer than electronic eng. Read times previous topic – next topic. Hi Guys, I just received my Arduino in the post a few days ago and have been having great fun with it. It has a serial and a paralell interface.
I have these working so on to my next problem. BroHogan God Member Posts: When the IC is operating in the parallel mode, these pins become floating.
I think what you want is an IC that takes something the arduino can talk to easily, like serial, i2c, etc. I have searched the internet far and wide for the past few days and I have come up blank.
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. X Y Pad No. Would I just connect the data pin of the IC to the pin 1 of my arduino to send the serial data to it?
