[[BUG] Waveforms 3.21.3 UART Protocol analyser does not work]

Hi @gabagool

I thought you were using Digital Discovery, which can adjust the DIO voltage, but Analog Discovery doesn't have such features.

What UART rate are you using ?

[Generation of sin square wave with waiting time.]

Hi @ohkubo

Yes, see the following:

[RISC-V CPU Support (BeagleV Fire)]

Hi @Ronnie

Unfortunately there are no plans yet as this would first require FTDI drivers for this architecture.

[Firmware Update failing on my ADP3450]

Hi @bfpa40

The communication errors are probably related to the computer or OS.
You could try to see if any useful information is printed on the ADP3450 UART.

[Analog Discovery 2 PYDWF Issues with parallel instruments]

Hi @dramnytz

Yes, all the instruments (oscilloscope, logic analyzer, pattern generator, and each awg channel) operate independently in parallel in the device FPGA. These can be synchronized with internal or external triggers, and awg channels can be locked to work synchronized.

[Digital Discovery Scripting]

Hi @engrpetero

'undefined' indicates that the script was executed but did not return anything.

[Digital Discovery - Step Back]

Hi @engrpetero

Enabling "Debug with Logic Analyzer" will open a Logic interface if it is not already open and add the currently used protocol and options.
After that, the Logic settings can be modified and additional interpreters can be added.

[Digital Discovery - Step Back]

Hi @engrpetero

The Protocol tool uses the device Pattern Generator and Logic Analyzer resources. When the Protocol is used the Patterns and Logic show Busy state.
When the "Debug with Logic Analyzer" option is enabled, the Logic Analyzer can be used to investigate the signals. In this case, the Protocol instrument will not receive data, it will only send data.
You can have multiple instruments open and the last used takes control over the specific device resource.

[Logic Detector as trigger in Scope. Is it possible?]

Hi @m72

Thank you for the observation. It is fixed for the next version.

[Analog Discovery 3 WaveForms - Automotive Measurements - Custom Probes Needed Please]

Hi @JonD

Is this what you are looking for? Are there other options to consider adding?

[Idle Vout of V+ at AD3]

Hi @plswelcomeroh

This is expected. It is the leakage current from the voltage monitor and setting rails.
It can be minimize with a dummy load, like 1k resistor.

[Analog Discovery 3 WaveForms - Automotive Measurements - Custom Probes Needed Please]

Hi @JonD

The Zmod Scope, AWG, Digitizer have SMA connectors.
EclyplseZ7 is primarily a development board but it can be also be used with WaveForms.
https://digilent.com/reference/programmable-logic/eclypse-z7/start
https://digilent.com/reference/zmod/scope/reference-manual

I'll try to add display modes after I return from holidays, tomorrow.
The custom probes probably later since this may require more time to implement (due to the overlapping code) and I'll have to focus on nextgen devices.

[Script, Time between pulses, DIO0]

Hi @Steve Pratt

Please use "CyclesMin" or "CyclesMax"
It will be fixed in the next version.

[Suitability of AD3 as digitizer for the vhs-decode project]

Hi @joebobjoe

The AD3 can capture at up to 125MHz on up to 2 (8) channels up to 64k (2x32k) sample device buffer. The record streaming is also sampled at 16bit/channel, can work at up to 10MHz on 1 channel, 5MHz 2 channels. The inputs are differential and DC coupled, with BNC adapter single ended and AC/DC switch.
The ADP3x50 and EclypseZ7 have device buffer of 128/256Mi samples, allowing to capture up to 125MHz on up to 4 channels.

[Testing Network and Impedance Analyzer using python]

Hi @kjhalek

Have you seen the examples ?

[Audio Adapter + stereo mode performance debugging?]

Hi @Andy-205

The board has 4 layers: top, bottom, GNDA(left)|GND(right), V-(left)|V+(right)
Pins 28-30 should reliably connect to TP1-3 since these are on GNDA, a large internal plane on the left side.
I only have revA and B prototypes, so I'll have to ask my colleagues to check this next week.

[AD3 appearing in device manager but not detected by Waveforms]

Hi @nanderson

The AD does not use the COM port but a faster communication method with the device. The Virtual Com Port is disabled in the device eeprom, but this can be overridden from the computer. If this is enabled and an application opens this it will block WaveForms access to the device.
Make sure the 'Load VCP' is unchecked, see:

 

[Digital Discovery software install error]

Hi @PS_Spectra7

It looks like MSVC 14 is missing/broken on your system.
Check the following to install it or from https://aka.ms/vs/17/release/vc_redist.arm64.exe

[Analog Discovery 3 WaveForms - Automotive Measurements - Custom Probes Needed Please]

Hi @JonD

Do the Custom Probes need anything else than unit, attenuation and offset shift adjustment?
Under Option you can find "Channel Editor" where channels can be configured quickly. (I think I added this after your earlier question in this topic.)
You could also save project or workspace for different setups (probes, views... ). This may be more useful than having custom probe option.

Segments Display, are you looking for the View/Persistence ?
Persistence is also available in XY and XYZ view, and Spectrum Analyzer.

Peak Detect, Channel # / Sample Mode: Min/Max

There are no plans yet for 4 Channel Affordable Scope, but newer WaveForms versions provide dual mode which lets you control 2 identical devices at the same time. See the Help tab/ Waveforms/Device manager and AD3/System frequency
4 scope channels are available in ADP3450, EclypseZ7 with 2 Scope, Digitizer... Zmods

[Rs and Xs calculation]

Hi @Magda

The magnitudeRatio is C1/C2 FFT magnitude at the frequency step.

[AD3 appearing in device manager but not detected by Waveforms]

Hi @nanderson

1. Have you checked the used driver version, as shown in the other post ?

 

I've seen 'broken' Windows where the driver files are not getting replaced.

2. To clean up the system from 'bad' drivers see the following post:

 

3. Verify the ftd2xx.dll version located in C:/Windows/System32

As a secondary solution you could try to copy C:\Program Files (x86)\Digilent\Runtime\UsbDriver\amd64\ ftd2xx64.dll
so WaveForms to use the correct dll version to: C:\Program Files (x86)\Digilent\WaveForms3\ as ftd2xx.dll 
or for the entire system to: C:\Windows\System32\ as ftd2xx.dll
