Tue Apr 26, You’ll rarely find things explained the way you want in technical documentation.

That thought led me to consider the SS line, the Slave Select signal. Good news is their ‘design notes’ PDF is very well documented so you might only have to make 2 pots of coffee to get it up and running.

Jsd1740, it probably is not necessary to build one. This is in response to a PM that came to me recently and I thought it would be better handled in the forum. Seriously, have a copy by your computer, by your bed, and in the bathroom.

This should have everything you need to make it work plus a little extra. I’ll try again using all defined pins, thanks for confirming my confusion!

The pins have built-in pull-up resisters. Hope these thoughts help you along. Ise1740 seems the ISD just doesn’t like to cooperate. Hope you don’t feel irritating that I keep asking the stupid question. But I also have some questions and problems to resolve in getting other commands to function properly and getting multiple commands to work together. What’s odd — for my application, anyway — is that you cannot write the Play Pointer directly.

Actually we need to modify the circuit? Hello cincailo, I have not found any problems with the schematics in the ISD manual. From, cincailo Thomas Taylor said Please give me some information about that, with standalone mode only, because i can’t make on SPI mode more isd1704 in my schedule [noparse]: I now have successful 2-way communication with the ISD.

I have not been able to get back to working on the audio level aspect and lsd1740 that I might be doing something wrong and the chip will perform better when I become better acquainted with it. Thats the part what i dont understand correctly.

Datqsheet it seem really hard to use this chip. Some let you know that everything went well or is normal. Display posts from previous: I would like to hear from anyone who uses this chip and has had satisfactory experience with the audio datsheet.

But for step 6, datqsheet need to design our own board? It was just easier for me to learn the standalone mode first, then the SPI mode with the assembly programming of the SX I put all my manual in a three ring binder with section tabs. I’ve attached my latest “lab” code; it seems to work as I intended.

All the extra copies of special pages I had right before me or posted on a board in EASY reading distance.

As far as the analog paths: This was my journey into the ISD series. For hardware SPI, you can reverse the bits by calling a routine before you send data to the chip, and after you receive it. You can go with the default settings unless there is something in your design that dictates otherwise. However, as I said, I feel it was fundamental to catching my misunderstanding.

So the code I wrote has everything you need to record and playback sounds of varying length.

I’ve never done this before, is there any special care or extra setup I should consider? I did some testing with a 16F with your version of the compiler.

I think there is a problem with the 16F data sheet. Mon Apr 25, 5: I’m from the old school. How can i obtain start AND end addresses of a sound. I don’t have the 16F, but they are in the same family. I found my problem as to why I could not execute one ISD command after another. Still absolutely no response from the ISD unfortunately, but I’m confident the program is correct now.

I used the analog input Anain. Look at section 8. SRC SX forum code See the end of this post for an example, and a link to some routines that reverse the bits: When they are there…and when they are not there.

Mon Apr 25, 6: Hello everyone, I hope someone can dataasheet some things up for me on this forum, about the isd17xx. These will be handy to have right next to as you will be thumbing through the rest of the manual all the time while still referring to these pages.

I like to see the bits — every one of them! I also tried ksd1740 the engineers for Nuvoton but they don’t seem to exist in the US.
