Hi @salman

See the following post:

 

[I2C Communication for MCP9600]

Hi @Alt

Do you have a I2C master which controls the MCP9600 ?
What is the I2C frequency ? you have set the Logic Analyzer to 100Hz but you probably need at least 4x the I2C freq for correct interpretation

[Digital Discovery to collect 16 bit SPI data - multiple slaves with same CS, CLK, MOSI and individual MISO]

Hi @Shalin

In your screenshot the MISO does not look right, it is very noisy, normally this should be stable for a clock period.
Such noisy MISO can not be received, interpreted correctly.

Hi @Shalin

For me you project returns the loopback data correctly.
Have you changed anything else in the subVIs ?

You have changed the MISO to be #4 DIO28
With a wire between MOSI-DIO26 and MISO the capture is correct:

Hi @Shalin

Are you using the latest software version ?

 

[DWF documentation issues]

Hi @reddish

Yes, it is corrected.

Feel free to ask if something is unclear.

Hi @Pauluck

This Record stores raw samples, use the Protocol for SPI data.

[DWF documentation issues]

Hi @reddish

Thank you for the observation.

The header file always contains the correct definition.

As usual, I corrected and replied immediately, but for some reason it seems that the message was not sent.

Hi @Shalin

Make sure you are looking at the correct MISO wire.

Hi @samuel.cregut

Use the Protocol/SPI/Spy.
Under View menu you can adjust the history (max lines) or use receive to file for even more data.
The latest version adds multi CS/MISO and receive to binary file options:

Hi @Josh Williams

I almost forgot the DPS3340, which can be used as AWG (in voltage or current) and Meter with 1kHz update rate.

I hope this helps:

Hi @Josh Williams

Power Adapter for Analog Discovery (1,2,3) is in works, it should be available in a few months

The ADP5250 DMM is intended for precision rather than speed. This is a rebranded VirtualBench with 1/2channel 1G/500MHz oscilloscope, AWG, power supplies, DMM, without special hardware features, no: record, play, pattern generator, protocols... and supported only under Windows.

[AD2: Trigger Wavegen1 from a Patterns DIO# using Trigger T1 on the fly wires. Minimize trigger delay]

Hi @tdavis

The outputs have a certain delay from trigger, digital pipelining + DAC.. The AWG output to be exactly in phase with the DIO, it should be triggered earlier and wait used to align.
For AD2 the Wavegen delay is about 160ns, so 3us + 11.84us will be in phase with the Patterns T0+15us signal. patterns wavegen.dwf3work

Hi @tdavis

See the following setup as a solution:

[Analog Discovery 2 not recognized by windows]

Hi @A.Chuck

Glad to hear that.

The USB controller does not need to be programmed since the IDs are stored in external EEPROM.

[Digital Discovery to collect 16 bit SPI data - multiple slaves with same CS, CLK, MOSI and individual MISO]

Hi @Shalin

See the example I attached earlier.
In C code a pointer can point to one value or to an array. In LabVIEW make sure to use the proper type.

Hi @Reet02

I wanted to say Python, but it got autocorrected to Phone.

Hi @Ostin Flores

There are no examples in C# but the Python Phone ones can be used as pseudo code examples.

Hi @MaciejR

You can disable auto-configure with FDwfDeviceAutoConfigureSet(hdwf, 0) and use FDwfAnalog/DigitalOut/InConfigure when needed.

Hi @Ostin Flores

You can find a C# wrapper in WF SDK/ samples/ cs/

Edit: I recommend using the newer version since if fixes a NA bug of 3.20.1

 

 

[AD PRO 3000 Waveform SDK]

Hi @Take4

The ADP3X50 input channels have two input ranges 2V and 50V. Configure dwf.FDwfAnalogInChannelRangeSet(hdwf, channel#, c_double(2.0))

With newer software version you don't have to complicate with Record mode, the default normal (acqmodeSingle) allows you to capture 128Mi samples, see AnalogIn_Trigger.py and other examples.

The latest versions also provide device buffering, memory segmentation, low latency <1us for consecutive captures.
