Friends, please help me,
I need to assemble a player without a recording, the simple as possible for an ISD1760 chip corder. The esquematic only needs to have PLAY, FORWARD and ERASE, a 5V regulator, output AUD / AUX and nothing more. The output will go to the powered speakers my computer.
Please help me with the layout, because I have urgency to Introduce this project.
Thank you
MAFONI
You might want to try a search for isd1760 on this forum. This is what I got: http://www.picbasic.co.uk/forum/show...9896#post69896
Friend, I am not looking for code programming, but only the electronic circuit diagram of the player.Quote:

Well then, how about this one? http://media.digikey.com/pdf/Data%20...SD-COB1700.pdf
Friend, this recorder has too. I just need the playback.Quote:

I think I cannot help you, because I don't know what you are up to. Perhaps you can tell us more about what you are trying to do.Quote:

If I were you, and from what you have told us so far, you could edit the schematic I sent you. Here it is without the record button. But again, I don't seem to have a clue what you are up to. Maybe I am doing your homework? Really can't tell.

Friend, if homework, would not be asking for your help and yes my teacher.Quote:

When starting a particular key on the radio transmitter, the corresponding sound will be activated in the corder chip, I already have a system that will convert the digital signal from the transmitter to the receiver's analog, or activate sound through the key / jump PLAY. The sound is amplified by a mini amplifier, PC type of computer boxes.
The sounds are recorded separately, according to the need and timing for this is that the only accurate part of playback.
I tried to mount a circuit based on this scheme but its not work, do not know if what I called did not have to call and / or did not care what they had to call, so I'm asking only the outline of the relevant part of the circuit and FORWARD PLAY, no longer need the ERASE, when I have to delete something from your recorder, you have to be very simple and small.
Now that you know what I want to do, could you help me?
Perhaps, as my English is not the best, is not making me understand, sorry.
Looking forward,
MAFONI
Thanks Mafoni,
Are you going to be building this hardware? And if you are going to build it, you can pretty much build it any size you want.
Or are you are searching for pre-built hardware? If so, why are you asking specifically for a ISD1700 device?
Mafoni, I have PM:ed you
Yes I will build and use a ISD1760 and other 1730 devices.Quote:

Here is a schematic for one that is controlled with a PIC12F683, and the example PicBasic Pro code. This example uses a similar demo board to the one I referred to earlier. So between the two, you have a full schematic of the interface, and all the supporting electronics. Since you are building it, edit it as you please, and build it like you want.Quote:

One question, for playback only ever get to use a device programmed PIC? I can not do it in very simple way as were the players in the ISD 2500 series (schematic attached)?Quote:

It looks like the ISD1700 series requires more external components than the ISD 2500 series.Quote:

Could you tell me what these components, only the portion of the playback.Quote:

You could remove the two "Optional" blocks on the lower right, and you could remove the microphone. However, you would not have a way to record anything into your device. You could remove all push buttons except for play. The data sheet says to keep all the other capacitors in there for good voice quality. You can probably get rid of the LED. I'm not really sure about what else you could give up. Reset seems nice to have.
EDIT : I did find a schematic someone made for an alarm clock that used the ISD1700 series. It has omitted many parts that the data sheet recommended. Not sure about the quality difference. Attached is that schematic.

Thanks.
These are really good one and worthy to visit here. I think so that this one is great
totally relevant to the post and it was good experience to read
