Equiry about the addressing method for multiple messages for ISD Thread starter cincailo Start date Feb 27, Hi, I’m now doing a project and need to record some segments of voice for example voice1 till voice26 replay them randomly.

There is a bit confusion and I hope that somebody may give me some hints. So I plan to set up the circuit for recording purpose only without PIC as in the application notes of ISD, then connect all the address line A0 to A9 to push button.

After that, I want to know which sound store in what addressI play it back and use the push button for addresses A0-A9 as I mention above to determine which sound in what address.

For example, 01 A9-A0 it play back the voice1. So voice1 address is Then after i determine all address for voice1 till voice26, I will write a C programming into my PIC, declare the address for voice1 till voice26 and when to play them which input button to press to PIC input pins.

It will automatically set EOM when i finish record one voice? Since there is no push button or any switches in EOM pin. When I want to play back the voice, it should be will automatically playback right?

So It is not using the push button for address only it will play back. How to set this? To erase all the voice I have recorded, it is I just need to reset my chip? Since the datasheet stated not to connect them. But if not, my PIC will know what my program state about the address? Hope you can understand what I mean. Hi, Attach the datasheet for ISD series just in case you want to review it. I don’t have that. What is it use for? What you will be doing with that, is determine the length and starting address of each message.


I would setup the chip circuit in a breadboard with dip-switches and pull-down resistors on the address lines. You will set the address of the first message, at binary zero. Then use the dataeheet to record the message at that address.

Change the dip-switches for the second address and record. And so forth for the other messages. The information in that will help you select specific addresses in the chipcorder’s memory to place your messages. The PIC can then use these addresses to play back each message. I could not find a link at Winbond for this document, so I am attaching scanned copies.

I had said that you should set up a dtaasheet for recording, but there is no reason that the whole process could not be controlled by darasheet PIC. Though the breadboard and manual operation might be better until you get comfortable with the address and control processes.

Ya, thank you very much. I get what you mean. So will try to understand the datasheet and try on breadboard first. Boncuk New Member Mar 3, Hi cincailo, I wonder why you plan using the ISD It also has longer recording time. Hi Boncuk, Nice to see you. It is a much more challenging chip to understand compare to ISD Just want to make sure that the method of addressing that you told me actually I need to set my ISD into operational mode or do nothing about that?

As you know that the A0 till A9 address bus can be address and can also be the selection of operational mode.

Equiry about the addressing method for multiple messages for ISD2560

Hi, Facing a problem here. The CE is edge sensitive, is there any way to change it to level sensitive without entering the mode operation? When playback, it will voice out sound1 but when the switch is not release, it will play sound1, sound2, sound I don’t want that.

I want it to voice out sound1, even though the switch is not release, it is still sound1. Have try to change the programming in PIC but seem no way to make it only voice sound1. So thinking is it the CE edge sensitive problem.

From, cincailo KMoffett said: You will not be using “MODE”, you will be using direct addressing. So, A8 and A9 are held low, and you will address the chip with A0 through A7. I’m going to start to the same cincailo’s road Parallel data adressing is light in terms of power so, you can keep free your PIC to examine the rest.


And very simple code to write I love this solution!!! And thnaks to KMoffet for providing disappered datasheets! I’ve knew it yesterday Ya, ISD17xx series will be good choice. Maybe would be ok for both keep our contact to exchange materials and experience in implementing it as slave of PIC.

Thanks David for hints Actually i’ve found an Honk Kong ebay seller where i have buyed already received 10 isdso, for now, parallel addressing will be my way. But, anyway, seems better to implement in a project already strctured due its semplicity parallel addressing and facility and low resource needed to run it. To got running by parallel addresing a is very simple; you have set up a time counter by your PIC and transfer data on addres inputs; put LOW play pin and after ms put down CE.

Then start the counter for time required to play only the frame you need, at timer owerflow, put again high CE and play pin at moment i don’t remember its number and will stop playng. I’ll go to implemet software in next days now just realized a little try Let me know if you’ll need more suggestion. Thanks for David and Pirvcb. For ISD, there are actually a lot ways to run the parallel addressing.

Understand your method but then how about when recording?

I found out one problem about my method is that when recording. It seem it will take 1. Isr2560p what I mean? Don’t know this problem can eliminate or not by time counter method. Looking forward for your answer. By the way, why ISD is not a good choice? Just because you get the C programming for ISD?

Can you send the C programming and related info about ISD to me?

Actually I datasheer few ISD on hand too, may survey it. You must log in or register to reply here. Replacement Transformer Started by ncag 9 minutes ago Replies: Datasheets, Manuals or Parts.
