When using the SDP-S daughter board to control/interact with the AD5668SD_Z eval board, i am encountering an "Error connection" message that shuts down the software interface for the eval board. i have the driver, am supplying power to the eval board, and have all jumpers in their proper locations. in spite of this, the error connection message keeps me from interacting with the software, and i cannot make use of the eval board.

What kind of troubleshooting can be done, and how can this be resolved?

EVAL-AD7124-4ASDZ detected as AD579x board in ACE – EEPROM ID issue

MSKAnalysis — Mon, 22 Sep 2025 05:29:32 GMT

Using SDP-CB1Z + EVAL-AD7124-4ASDZ. ACE recognises it as board.ad579x_8x_6x. I suspect wrong EEPROM ID. If this is an EEPROM issue can I get the correct EEPROM file or programming utility? The board is also not recognised by the AD7124 Eval+ software its states: "No supported evaluation boards found" on start up

I am using the SDP-S Controller Board to control EVAL-ADF4110, and the evaluation software is not very convenient to use. I want to directly use Python to control the frequency output of EVAL-ADF4110. SDP-S cannot recognize the code value I am sending, so do you have the control protocol and communication protocol of the SDP-S Controller Board or a more detailed command list and example code.

EVAL-SDP-CH1Z data streaming

JEstayo — Mon, 14 Apr 2025 03:25:17 GMT

Hi,

Can someone please advise if the SDP-H1 can be configured as described in the thread below to allow data streaming?

Thank you!

(+) Streaming data with the AD4134 eval board and SDP-H1 - Q&A - Precision ADCs - EngineerZone

"Hello,

I'm evaluating the AD4134 as a candidate ADC for a low-noise measurement we are developing. I managed to get the combination of EVAL-AD4134 and the SDP-H1 evaluation boards working and talking to each other. However, I can only record a maximum of ~100ksamples with the ACE software that ships with the SDP-H1. What I'd like to do is to stream data off the EVAL-AD4134 / SDP-H1 and write it to disk for later processing, can I reconfigure the SDP-H1 to function in this way? I believe USB supports enough bandwidth for me to stream 4 channels of 24-bit data at ~1 MSPS so I don't expect that to be a bottleneck, but ideally, I'd like to use the on-board memory buffer on the SDP-H1 such that I do not suffer any discontinuities. Browsing the forum, I came across this thread but some of the links there are broken, so I figured I'd ask if anyone has had a similar application requirement and managed to get the combination of SDP-H1 and EVAL-AD4134 working.

Thanks!"

Controlling EVAL-ADF4107 + SDP-S from Python

qwertyu — Tue, 11 Mar 2025 13:06:36 GMT

I have an EVAL-ADF4107 that is connected with an SDP-S to a Windows PC. Currently, the system is manually controlled with the GUI of the `Integer-N Software (Rev. 7.7.4)` that is found [here](https://www.analog.com/en/resources/evaluation-hardware-and-software/evaluation-boards-kits/eval-adf4107.html#eb-documentation). I would like to know whether it is possible to control it from Python. If yes, I would appreciate any hints on how to do this.

13 Hz interference seen on SPI of EVAL-SDP-CH1Z

Regarding generation of AC signal through EVAL-CN0350-PMDZ kit for proper frequency analysis

SFZ — Tue, 07 Jan 2025 07:45:12 GMT

I have purchased your product whole kit of consisting 1. EVAL-CN0350-PMDZ 2. EVAL-SDP-CB1Z 3.SDP-PMD-IB1Z , as i wanted to generate signal form my PZT sensor for frequency analysis in the CN0350 software, but my problem is that its not generating proper AC signals , which are preferred in my study.

Following pics show the response I am getting, which is not at all helpful in analysis and is absurd

Following is some examples of the kind of response I require for my urgent analysis ( well refined AC signal, as PZT generates AC voltage/charge)

And following is my circuit I used

Please help me solve this situation as soon as possible, so that I move ahead with my study

SFZ — Thu, 26 Dec 2024 07:13:52 GMT

Hello,

I recently purchased your product of all accessories required with EVAL-CN0350-PMDZ, now the issue is with the software version not supporting the SDP board it keeps showing the following window, it look like I have an older CN0350 software version which does not apparently seems to work with my Windows 10 version

This type of window appears , although I have downloaded the ADI SDP driver, but still the problem is persistent and it also shows in my device manager.

Please can you provide a solution to this , its very important for my doctoral work.

The SDP-S cannot connect to the EV-RADAR-MMIC2

opensky — Sat, 21 Dec 2024 01:31:59 GMT

We have created an evaluation board based on the EVAL-RADAR-MMIC and are using it to connect to the SDP-S via a 120-pin connector. However, the evaluation board is not being recognized, which seems to be an issue with the EPROM. How can I program the EPROM?Can you provide the EPROM file?

Thank you very much.

Reading out data through python not working [installation problems]

bdck — Fri, 18 Oct 2024 07:25:55 GMT

Hi, thanks in advance for any help:

Setup:

ADXL313z accelerometer sensor -> sdp interface board rev2 -> blackfin eval-sdp-cb1z -> usb -> computer

on my laptop: win11, python 10, vscode with ubuntu WSL active, venv active

The board is already shared to wsl: lsusb shows `Bus 001 Device 002: ID 0456:b630 Analog Devices, Inc. Blackfin USB Device`

Issue: I cannot get my python code to access the data from the sensor. It never finds the sensor.

Also iio_config does not seem to ever work (i suspect the problem is here)
Library version: 0.23 (git tag: v0.23)

Compiled with backends: local xml ip usb

Unable to create Local IIO context : No such file or directory (2)

What i tried(i tried alot):

sudo dpkg -i libiio-0.26.ga0eca0d-Linux-Ubuntu-22.04.deb

pip install pylibiio

pip install pyadi-iio

Current code:

import adi

# Create the device interface using the USB bus and device number

sdr = adi.adxl313(uri="usb:1.2") # Bus 001, Device 002

# Read data from the device

data = sdr.rx()

# Print the data

print(data)

SDP-B Controller board can not detect the Eval board

Jackie1 — Wed, 02 Oct 2024 20:48:13 GMT

I am using the EVAL-SDP-CB1Z board to interface with the EVAL-AD5421SDZ.

I am dealing with the common error I have seen on here, which is the board can not be detected.

It is my understanding that the startup of the evaluation software first tries to read a serial number from the EEprom on the AD5421SDZ.

This is the detection process that fails. I have uninstalled and reinstalled the drivers several times and according to some notes on the FAQ, the drivers for the SDP-B are installed correctly. The device manager indicates that the the SDP-B board is connected to the PC via USB. See screen shot.

I have 24 VDC connected to the J7 connector on the AD5421SDZ board. However, I have no indication if the board is powered on. I would suspect that either the board is not on or the EEprom does not have the serial number required to have the board detected.

Is there an optional way to power the AD5421SDZ board? Is there a way to determine if it is powered on?

It is very disappointing that this is the issue that has to be dealt with before doing any evaluation work.

I have seen responses to others with this similar problem and they are told that there is not any time to deal with SDP-B board issues.

This is not a very good response to customers that are trying to evaluate a part that they may want to use in a design. If you do not have time to assist customers with the boards you have built, well then we do not have time to evaluate your part for our design. This means we move on to another manufacture for the parts that we use in our designs.

Please let me know if you have any positive ideas as to the way to solve this issue.

Thank you,

Data stream from ADAR3000/3001-EVALZ collect

Meloni — Wed, 11 Sep 2024 09:08:07 GMT

I'm trying to collect the data stream from ADAR3000/3001-EVALZ in Matlab or C/C++/C#
This should be possible, but the documentation is lacking. The hardware works fine in the AD ACE software and SDP-S Controller Board, but I would like to do the acquisition directly on Matlab, etc....
Possibly? How so?
Thank you all for the information.

EVAL-AD5781 can't be controlled by ACE

howardaaa — Fri, 07 Jun 2024 06:56:09 GMT

Hi,

I've got 1 EVAL-AD5781SDZ(REV B) and 1 EVAL-SDP-CB1Z.

And I power EVAL-AD5781SDZ through J11 with 5V supply.

I connect EVAL-AD5781SDZ J4 with EVAL-SDP-CB1Z J14.

I connect USB of EVAL-SDP-CB1Z with my laptop.

I opened ACE and it can detect EVAL-AD5781SDZ.

But I can't control AD5781 with ACE software, the screen is shown below.

The connection is as described in the user guide

EVAL-AD5781SDZ (Rev. 0) (analog.com)

And I measured, VDD=+13.7V， VSS=-14V, IOVCC=3.3V.

What could be wrong?

What else do I need to check?

EVAL-SDP-CB1Z + dual EVAL-AD7616

mpe1994 — Fri, 17 May 2024 06:52:37 GMT

Hey there,

I just started using the EVAL-AD7616 with the SDP-B controller (EVAL-SDP-CB1Z) on Windows PC. I need to convert 24 analog channels, so I'm planning to use 2x AD7616 to have up to 32 channels.

I would like to use a single master board (i.e., 1x SDP-B) to control at the same time 2x EVAL-AD7616 and acquire data via the evaluation software. First, can I do this? I understand that connectors A and B of the SDP-B share some pins, and there are 3 SPI interfaces. Can I connect 2x EVAL-AD7616 to the same SDP-B evaluation board? Can the software control the two of them?

Hope my questions are clear!

Best,

MPE

Windows unable to find EVAL-575XSDZ with SDP-S

acording — Mon, 06 May 2024 14:25:30 GMT

Hello,

I just received an EVAL-AD5755-1SDZ and SDP-S to test a DAC I am going to be working with.

I connected the power as shows in the datasheet, supplying the eval board with +/-15V for AVDD and AVSS respectively and 5V to AVCC. When I apply power I see D2 turn on green, see picture.

I also connected the SDP-S to my Windows 11 Laptop and I see PWR is green and LED1 is amber (not sure what this means, the datasheet just says it is for application developers), see picture.

I can see the SDP-S show up in Device Manager as well, see picture.

After all that when I open the AD575X Evaluation Software it says that no matching system is found, see picture.

I have tried to re-install the drivers and the program. Used both the online version and the version that came on the CD in the box. I have tried numerous USB ports and PC restarts.

I am not able to get Windows to recognize this dev board. Any help is appreciated.

Consultation on AD4134 communication and FPGA code

yifang — Wed, 20 Mar 2024 01:59:19 GMT

Hello,

We have an actual situation based on using your AD7760 product, but during testing, we found that the waveform it collected always has overshoot and ringing phenomena at the edges that cannot be filtered out. Afterwards, we purchased your products EVAL-AD4134FMCZ and EVAL-SDP-CH1Z for testing, and were quite satisfied with the performance of the AD4134 chip. We would like to use the AD4134 chip to replace the AD7760 for development and design. However, as we are not very familiar with AD4134, and after referring to some information on your official website and forum, we found that there is still a lack of information about AD4134 communication and FPGA code. May I ask if you can provide us with some information.

Control problem of SDP-H1

APTX4869321 — Sun, 03 Mar 2024 10:41:36 GMT

The SDP-H1 manual says that a pin is reserved to trigger and control the FPGA, as shown in the picture, then how should I use this pin to trigger the FPGA, my purpose is to achieve the function that the FPGA will output only when the trigger comes？

Header Support for AnalogDevices.DPG.EvaluationBoards.dll

mihaim — Tue, 30 Jan 2024 11:08:43 GMT

Hi,

I am looking to source the header files for the SDP (SDP-S) driver. Currently I have the AnalogDevices.DPG.EvaluationBoards.dll but need the header file to load into LabView.

I would like to get some more information on the .dll specifically how to use the API's from C and LabView. LabView should typically open a session, read/write some spi's, close session. Each session will be linked to a specific usb / virtual serial port. If there's a manual that could be supplied, that would be great.

If not, is there any way I could get another .dll that would work with LabView? Any help would be appreciated.

Kind regards,

Mihai
