Hi @DZe

 

Hi @AbbyM
For 64bit ARM the arm64 and for 32bit ARM the armhf should be used.
You have in message the links to a newer release candidate version.

Hi @rim
This seems to be a bug in the underlying libraries, Qt5.12, when 3D plots are above each other.
It is solved in Qt5.15 and this will be used in the next installer if all other things work correctly.
Thank you for the observation.

Hi @AbbyM
See the Help and reference page:

Hi @AbbyM
1. For better ethernet performance use a local switch or direct connection.
With AD2 USB I can get 1-2MSps, this device always records at 2 channels.
With ADP3X50 the earlier mentioned DDRam buffered recording limits (128MSps@125MHz/1ch...) and for longer or through linux mode 2-4MSps for 1 channel, this device will record on the enabled 1,2,4 channels.
The sustainable streaming rate depends on the computer, available usb bandwidth, controller performance, cpu...


 
2. Yes, see the WF app Help

 
The instruments (Scope, Wavegen...) are implemented in the Zynq Programmable Logic. The standard firmware or embedded Linux runs in the Zynq Processing System. The PL and PS communicates through AXI.

Hi @Ricky
Sure, pic 1
With the 6th device configuration the supplies can also be used as slow AWGs, pic 2

Hi @AbbyM
See the application Help

Hi @HarissonJones
dwf.FDwfDeviceParamSet(hdwf, DwfParamFrequency, c_int(83360000)) # 8x 10.42MHz
dwf.FDwfDigitalOutEnableSet(hdwf, c_int(0), c_int(1)) # DIO (0) 24
dwf.FDwfDigitalOutDividerSet(hdwf, c_int(0), c_int(4)) # /4
dwf.FDwfDigitalOutCounterSet(hdwf, c_int(0), c_int(1), c_int(1)) # /(1+1)

Hi @crile
Yes and that is the default path, which can be changed on the first installation.

Hi @Anthocyanina
Yes. It depends on the noise. What you are seeing is the derivative +/- sample to sample noise it captures. In M1 I didn't multiply it with the rate so you can see a +/-~2mV noise.
You probably want if(isNaN(prev)) prev = C1; and having the initializer code var prev = NaN;  for the first sample to be zero.

Hi @crile
You can use it if you need it.
I've written this dwfcmd long time ago when the WF app was only for Windows to have some Linux support.
This dwfcmd app can be simply used (with arguments or command file) to control the devices (generate signals and capture) or its source code can be modified for specific tasks.

Hi @crile
The device should be closed when calling the close function. Are you calling the enum function again when before the isopened one because the infos are collected during enum ?
Device_Enumeration2.py

Hi @crile
I don't know which software version are you looking at but it seems to be ok in the latest version.
 
 

Hi @crile
I'm not a Python expert either. The prefixes are from my Hungarian notation coding habit...

Hi @crile
You can find a C# wrapper in the WF SDK/ cs/ dwf.cs, add this to your project. The examples are under py/ and some under c/ which can be used as pseudocode for examples for other languages.

Hi @crile
For digital output see the WF SDK/ samples/ py/ DigitalOut_Custom.py, DigitalOut_CustomBus.py ...
and for analog AnalogOut_Custom.py, AnalogOut_Pattern.py ... examples.

Hi @crile
You can use csv or a simple new line delimited list of values: default.csv
The source code of the dwfcmd app is also there.

Hi @Davidson.Cassagnol
You could use network/impedance functions. Take a look at the examples in WF SDK/ samples/ py/ 
AnalogImpedance_Analyzer.py
AnalogImpedance_Compensation.py
AnalogImpedance_Input.py
AnalogImpedance_Measure.py
AnalogImpedance_Meter.py
AnalogImpedance_OffsetSweep.py
AnalogImpedance_OffsetSweepCp.py
AnalogImpedance_ThinkSpeak.py
AnalogNetwork_Analyzer.py

Hi @LJH
See the following: ex1.py (changed to sine to be easier to verify)
If you are capturing less than 32Ki samples/channel you can use single capture mode.
You could use up to 32Ki samples for analog-out custom for higher resolution signal.
I recommend using the latest version sine beside other things it fixes some related to ADP3000 recording.
 

Hi @Anthocyanina
Just increase the height of the Bus or the interpreter you are using, specify format, skip bits if needed...
Alternatively in the Script tool you can add plots or transfer the Logic Analyzer data to Scope channel data or Wavegen...

Hi @AlanB
Here you can find the new version in which there is no need for DataSet after Configure:
Try with param stop. With run option, if the previously used application exited with shutdown the IO voltage level translators remain disabled.
dwf.FDwfParamSet(DwfParamOnClose, c_int(1)) # 0 = run, 1 = stop, 2 = shutdown
If the run option is needed, after open use the following to set the IO voltage and enable the translators:
# set digital voltage between 1.2 and 3.3V
dwf.FDwfAnalogIOChannelNodeSet(hdwf, c_int(0), c_int(0), c_double(3.3))
dwf.FDwfAnalogIOConfigure(hdwf, c_int(0)) 
The Digital Discovery play output captured with Analog Discovery:

Hi @LJH
See the following: adp3450.py
I've added trigger for analog-in, changed analog-out to custom mode since the number of samples fits in the buffer, changed the rate and run length
