Hi @bryan78

It is corrected in the latest version:

 

That looks like it fixes it, thank you

[ADP3250 fw 3.22.13]

Sorry it took me a while to get back.

Here I am triggering on break for uart and letting it run on repeat. after a while it just stops updating but says triggering. When using the smaller memory size It continues to repeat trigger.  I took a video to help explain the problem.  I am running it in Ethernet connection.  The versions should be visible in video.

[ADP3250 fw 3.22.13]

When I am using the various protocols like UART under Logic, I can not get it to trigger correctly when using the line 1 in device options.  If I change it to use line 2 then the device triggers as expected.   I am not exactly sure what the difference in functionality between the 2 memory setting but the first just doesn't seem to work correctly and that is the one it defaults to when starting a new workspace

Hi @bryan78

ADP5 is VirtualBench for which I cannot change the firmware.

Is there a way to use digital input of the digital discovery?  Thanks

Never mind,the counter already works in the digital discovery under the Logic analyzer.  Just wasn't in your list of supported devices.

Unfortunately the AD2 FPGA logic is full, such feature would not fit in the device.

Is there a way to enable it for the adp5250 if even at lower speeds, or the digital with using the digital inputs?  Thanks

@attila

Appreciate you adding it to the GUI, you're killing it 😃

@artvvb thanks, I will play around a bit more

[Wavegen Sweep to and from]

Is there a way to have the sweep go to and from a start and stop frequency instead of wrap around?  I have tried accomplishing it in a script but I am relying on setting the frequency time and using wait() to switch start and stop frequency.  This leads to un-smooth transfers or the possibility the timing is a bit off and it wraps around before stopping.

It's working. Appreciate it

[ADP-5250 DMM log]

Hi @bryan78

You could use the Script tool to print or log measurements to file.

DMM.run();
while(wait(2.0)){ // every 2 seconds
  print(DMM.Measure.value)
  //FileAppendLine("~/Desktop/log.txt", DMM.Measure.value)
}

I came back to this one once again.  Is there any chance in the future of adding an export or log to file option in the gui?

[Script for SPI]

Hi @bryan78

In newer versions the SPI transfers can automatically control the CS, so there is no need to use start/stop.
My intention was to make it backward compatible... start/stop will be fixed in the next version.

One other question about the scripting.  How do I switch back and forth between protocol reception and logic analyzer inside the script?

Ill try removing them all.   I spent a day on it until I figured out I could get it to work by setting active state opposite and somewhat works.  Glad I am not loosing my mind.   thanks

[Script for SPI]

in the Discovery2 when I run the example SPI script, it doesn't look. the Stop() is releasing the chip select.  Also to accomplish this I have to make the protocol setting opposite of what I am expecting.  I think the Stop and Start function are reversed???

[Adp5250 continuity]

Thanks for the latest feature.  May not be possible and also preference, but may be better if it latches the state until next check.  So it is a tone instead of constantly beeping.  Really like that it was also added to the voltages also, thanks.

[Differential signals]

It would be nice to have a feature to output a differential signal to replicate rs485.  I find myself often having to generate a pattern on one pin and then the inverse on another to drive a differential signal.   It would also be nice if this was available under protocols.

Hi @bryan78

There is no such option yet, but we can add it.

That would be great.  Keep me from having to look up.  If you are able to add that can you also add the inverse, break detection.  So beep either for good continuity or set to beep when open based on adjustable values. Thanks

[Adp5250 continuity]

Is there a way to make the continuity check under DMM beep under a set resistance?  I don’t see a way to enable it.

[SPI and I2C on adp5250]

@attila

I see, I thought the custom didn't work because of the data transfer error I got.

The sensor tab is greyed out for me.  Would want to use the sensor option to eliminate the long delays between chip selects,  but how could this be done if you use patterns to generate it?

 

[SPI and I2C on adp5250]

didn't want to flood the forum, just wanted to say thanks for jumping through some hoops to get SPI and I2C going for this.  Confused myself when testing because it took a second to realize you had to use the static IO lines for driving the signals. It looks like only single and dual spi are available, couldn't select the other data lines for quad.   Any other features you can add to the adp5250 with some creativity is greatly appreciated.  Could it be possible to replicate a sensor or custom script for it also ?  Just that next step would fill the gap in what its missing.  Wish we could just use patterns on it :)

Hi @sushant

The Digital Discovery has 256MiB of RAM, so the length for 32bit @ 100MHz is ~0.671sec
https://digilent.com/reference/test-and-measurement/digital-discovery/start

If you have multiple devices is it possible to have another record where the other stops? Like a trigger out for data full?

Hi @bryan78

The 'Repetition' channel/signal option is not available for Digital Discovery. Without this the pattern is repeated while the Pattern Generator is running.
The disabling of this option will be solved in the next version.
The next version won't list disconnected ADP5250. With the current sw version uncheck the Filter/Remote option.

is repetition setting option possible on the analog discovery2?  I hate when using the feature on the DD or 3450 and then breaks if I go to the ADiscovery 2,  thanks 

[SPI protocol]

Hi @bryan78

In Custom, Script and API the Select is software controlled so the timing is around 1ms.
With Sensor a custom pattern is built including the select signal with such timing:

Here is what I am getting

I think I got it,  the delay goes away when moving the functions to loop instead of initialize.  Is there a reason for this or documentation explaining it?  thanks

[SPI protocol]

When writing scripts for the SPI protocol, there is a long delay of over 1.5mS from chip select "Start()" to the clocking out of data.  is there a way to drastically reduce this?  It breaks the way an FPGA is expecting the data

[Adp3450 adapter]

Why is there no official interface for hooking up the impedance or curve tracer boards to the adp tools ?

thanks

[External Reference clock]

Appreciate it.  Any idea if it would be better, less phase noise if I have a clock at 50MHz compared to 10MHz?

[External Reference clock]

It looks like the adp3450 allows me to setup triggers as an external clock reference.  Is this really allowing me to use a precision reference clock and if so, do any of the other models allow the same thing?
