  1. Thanks for the answer. Maybe in the future there will be a chance to integrate hex editor in WF2.
  2. Hi @attila, Recently I have not been following updates on Waveforms software and I see a lot of new, interesting features, like AVR programmer. Of course now there might be requests to add programming feature for other uC (like STM32), but I came up with different idea, that in my opinion would be more useful. Quite often we have to read contents of some memories or program them (I2C, SPI, QSPI, Parallel are on my mind, like AT24CXX, ...). It would be super useful to turn AD/AD2/DD into memory programming, reading and editing tool tool (like read memory content to computer memory, display HEX view, edit, reprogram). Best regards and I would like to know what do you (as an developer) and other users think about the idea.
  3. Hi @attila, I do not know if it is a bug or a feature (to show where real acquisition signal level is), but: I set the Zero voltage for a channel The plot is going to requested position The histogram still is displaying data without zeroing Here I include image illustrating the problem, Zero value is set to 2.73...V:
  4. Hi @attila, Thanks for your reply and the script. It would be nice to have the data displayed in Power Supply window. Kind regards, Peter
  5. Hi, I was working with AD2 and DD for quite a time and I feel lack of one small feature: display overall current/input voltage consumption constantly. Now I am able to observe there parameters by clicking on "Status" button in the bottom right corner, but It would be nice to have an option to display these parameters in this status bar without a need to click on the button. This would be useful for me when playing with power supplies - by looking at these parameters I can clearly see if there si an issue in my system or not. Also, I do not know if the hardware has such ability, It would be nice to display current consumption of power supplies in power supply window. Best regards, PR
  6. @attila As always: Thank you very much Another suggestion: In scope we do have Average and Oversampling options. None is followed by maximum value, then decreasing to reach 1 (which is equivalent to none). Ex. for Oversampling, we have options arranged like this: None, 16, 8, 4, 2, 1 In my opinion better order would be to place None value next to minimal (and maybe replacing value of 1 by "1 (none)", so it will be: 16, 8, 4, 2, 1, None or 16, 8, 4, 2, 1 (none).
  7. Hi, Windows 7x64 Waveforms 3.8.22 (beta) Analog Discovery 2 / Digital Discovery Issue: inverting polarity in Protocol has no transfer to Logic analyzer window Steps to reproduce: Run Protocol Select UART Polarity: Inverted Click Logic Analyzer In Logic UART is set to be decoded with Standard polarity Suggestion: UART data should be also available with HEX formatting or other non-ASCII formats. Also an option to break line after N chars received would be nice Kind Regards
  8. You have to connect a CAN transceiver to the AD2 to provide a physical layer.
  9. Hi, @remalytics It can be definitely done by preparing custom software using Python, LabVIEW, etc...
  10. @attila, @Astro-Smart I am referring to Protocol window, where I can see ASCII representation of data. I am not sure if this representation will be visible in Protocol window only when it is selected in Logic, or permanently. If it is visible only when selected in Logic I think it would be ok, but permanently displaying ASCII in Protocol window may be confusing in some general use cases.
  11. Hi, @attila Would user be able to disable such decoding in Protocol mode? Sometimes such decoding is usefull, sometimes - it is not. Kind regards and thank's for a great job. PR
  12. These pins are disconnected from pin header in order to minimise parasitic parameters, I suppose. The only way to use BNC and 2.54 connector would be to solder some wires, but being aware that negative terminals of the scope are hardwired to GND. On the breadboard adapter all signals are routed to connectors. And you can use breadboard adapter with BNC adapter but with analog signals provided and probed using BNC cables/oscilloscope probes
  13. That would be suitable. I wonder if decoding some control characters would also be useful (like CR, LF).
  14. I also think that ascii representation would be nice as sometimes text data are being transmitted using other protocols.
  15. Hi, I have noticed an issue in WF 3.8.8 (beta) x64 Windows To reproduce: Run WF (device already plugged in - in my case DD) Run Protocol Enter a text in TX window (see attached image) Click send The Send button remains presses Click send again Change the text Click Send button Old text appears again ad. 3. ad. 5. ad. 6. ad. 9.
  16. TX and RX channels are defined in Protocol -> CAN Window: Functions for setting Rx and Tx channels are described in SDK Reference Manual: Also, in my opinion, you have to use a proper CAN transceiver for TX, as the transceiver is not only a level shifter, but realizes differential interface. Maybe you can monitor without a ttransceiver, if I/O threshold would be sufficient to voltage levels on one of CAN lines.
  17. Yes. First you should measure your resistance with a precise multimeter and enter it in Compensation window. Then open compensation is without load, and short is with shorted DUT terminals. Please be aware, that compensation should be repeated when you change frequency range, frequency step, etc.
  18. Have you performed calibration (open, short, ...)? Additionally such small capacitance can be a parasitic capacitance of cables, AD2 connector etc.
  19. Hi. I think that programming may be implemented quite easily using the WaveForms SDK (and for example a python script). In my opinion debugging would be harder to achieve, because it would require integration with existing debugging drivers.
  20. And also are you using USB cable provided with the AD2?
