Dear Thomas, Thank you so much. I extend my apologies to those who may have labored through my post.

(PDF) ISD1740 Datasheet download

Hello cincailo, I have not found any problems with the schematics in the ISD manual. However, it probably is not necessary to build one. In this table it lists SDO on pin 9. Is there a schematic available. Hope these thoughts help you along. But for step 6, we need to design our own board? As you write code and debug, keep rereading these rules.

It is a challenging chip.

I’m trying my own little prodject and I want good quality sound. I’ve attached my latest “lab” code; it seems to work as I intended.

Mon Apr 25, 6: Anyway, something wrong somewhere, I have fatasheet exactly the circuit in page 76 with a voltage regulator to supply it 5V.

Thank’s for your help. I’m sending 0x09 for Device ID, which is followed by 1 blank byte and the third byte holds the device ID information, but I’m getting nothing but back in the third byte.

Are you using a microphone or Anain? You referenced page I’ve attached a WIP program that may help you get connected. Hope you don’t feel irritating that Datasueet keep asking the stupid question. I ended up just using my design ratasheet for both standalone mode and SPI mode. All the extra copies of special pages I had right before me or posted on a board in EASY reading distance. Well it’s not the end of the world writing your own driver but how can they say it’s SPI interface if it’s not one of the 4 known SPI modes?

I have been away from the chip for a year, so this has been a good review datashheet me as I now have to get back to this aspect of my project. Maybe even upload onto the ‘working programs’ forum here, for others The second one is the actual 17 page document with photos and schematic for a programmer.

CCS does not monitor this forum on a regular basis. But my real need is to become fluent with each command in SPI mode. However, this section may be a simple test to answer your next question as to whether or not the ISD chip is good or defective. When the current sound completed, the other ISD picked up datashdet.

But it seem really hard to use this chip. Almost like reading a quote from my posting! Has anybody gotten any answers from Nuvoton, who now owns the ISD chip? Hello, I was wondering how you built your interface. Tue Apr 26, 2: I can now step through all the commands I have worked with, one after another, and all MISO data reports correctly. Basically, the question was asked as to how to start to learn to program the ISD series devices.

I try to set up the circuit for standalone mode as in page 76 but it seems can’t function at all. My problem is that I’m not getting the proper responses from the chip when I send commands.

It may flash once for you – see the instructions in 8.

SX asm question using SPI mode on ISD1700 ChipCorder series

I programmed assembly language and machine language back in the sixties just after we got radio and heard about TV. You just need to add the new commands for your chip.

Thank you so much. Thanking you for having read this far…and hoping you might be further up the trail. Otherwise I’ll have to bit bang this whole thing which is no big deal, but slightly annoying.

The pins have built-in pull-up resisters. It was just easier for me to learn the standalone mode first, then the SPI mode with the assembly programming of the SX During the course of many conversations their engineer said to me, “Well Thanks again for the help! Wed Jun 01, 2: I found my problem as to why I could not execute one ISD command after another. I’m from the old school. Note that the chip has an eight level stepping volume control. Hello everyone, I hope someone can clear some things up for me on this forum, about the isd17xx.
