  1. Further to my struggles here https://forum.digilentinc.com/topic/17957-open-logger-some-basic-doubts/?tab=comments#comment-46282 I must say today was a lucky day ... Yes the OpenLoggerMZ worked as it should with another laptop running WINDOWS 8.1. Using this opp i even upgraded the firmware to 0.1719.0 and all well. Could feed the Wavegen output to CH1 and could see the plot. Atleast the board is still not bricked ... whew !! Then try the same with WINDOWS 10 which is my own laptop. Nothing works . Board connects only in offline mode and even then reports OpenScopeMZ ( see the mess in the reporting .. OSMZ and bottom line reads OpenLoggerMZ) and of course nothing more happens. So its confirmed that this board is not working with WIN10. I even tried to invoke compatibility mode with WIN8.1. No luck
  2. Have just started playing with the OpenLogger that just arrived. Did a firmware update and calibration via a Windows 10 VM on a macOS machine, and connected the OpenLogger to wifi, all went fine. Is wifi meant to be working? If so, consider the following as a bug report. If not, then what's the ETA looking like? OL firmware version: whatever the latest is (how can I determine this from a running device? the UI should have some method of viewing the connected device's firmware version (e.g. in device manager?)) env: Chrome Version 73.0.3683.103 (Official Build) (64-bit); macOS 10.14.4 (18E226) However when connected to the OpenLogger via wifi I see frequent errors, including - "Error Occurred Starting Or Running Acquisition" when interacting with the timebase and amplitude (i.e. mouse zooming/scrolling) - "Could not set AWG parameters" when interacting with the AWG controls, changing modes There doesn't seem to be anything in the browser dev tools console when these occur. (the console does show a bunch of warnings re. 't' plugin and a CORS policy error just on loading the waveformslive.com page, but there's nothing additional when the acquisition error occurs). Repro: 0. OpenLogger connected to wifi 1. go to http://waveformslive.com/ 2. start streaming 3. interact with the UI - scroll back and forth, zoom in/out 4. in very short order one of the above error messages pops up; at this point the UI becomes unresponsive and a page reload / device reconnect is required Occasionally the device will get itself so confused it won't connect at all (WFL reports "No response received"), and a OL board reset is required. PS: there needs to be some sort of error log mechanism, it's a real pain to try and capture the errors via toasts....
  3. As you can tell from, my spate of messages, I'm playing with my OpenLogger - discovered this problem today: I wanted to use one of the two DC power supplies. I set DCOUT1 to 1V and measured on the board with a multimeter. Nothing. Turned it off and set DCOUT2 to 1V and measured. Nothing. Left DCOUT2 set to 1V and measured on DCOUT1 and yes, 1V is there, but it shouldn't be So, DCOUT1 on the interface is not working at all. DCOUT2 on the interface incorrectly directs output to DCOUT1 on the hardware.
  4. Hi to all !! Got my OpenLogger and installed Digilent Agent on my Windows 10 notebook. No errors. 1. Then followed line by line the Getting Started instructions. Have come stuck at the Device Identification via Agent. I just get a message " Error connecting to device " . What could be wrong ?? 2. Am I supposed to power up the board or only the USB cable is enough ? When exactly one use the DC power socket for power up? The manual is sadly silent on this ... 3. Instead of the Web based Waveforms Live how to host it locally on my PC ? When I try to enter http://localhost:42315 into Chrome browser I get a 404 response. I even tried to run the Agent in WIN8 compatibility mode. No use... SO what else do I need to check
  5. I got my Open logger on Monday and till date I have struggled enough but yet to see a single plot on screen. So have been wanting to get some tips in this thread...https://forum.digilentinc.com/topic/17957-open-logger-some-basic-doubts/ With no possibility of updating the firmware past the version 0.1691.0 and the WaveForms Live throwing up only errors its really frustrating.
  6. Greeting, I am interest to purchase the OpenLogger board. But have a question. Hope you can help to clarify. I want to use the device to collect data for analog K Thermocouple sensors Would it support analog input such as K type of thermocouple sensors? What are some of the K type thermocouple sensors it support? If the OpenLogger doesn't support is there a similar options? Thank you. Yoom
  7. Hi, I use OpenLogger to log data to the SD card. The saved data file is in the format of *.log. I tried to read it out by Matlab but failed. Could you give me some help? For example, what's the format of these data? Does it both include time and voltage? What's the header like? ... Thanks, Peggy
  8. Thanks for updating the new function of logging data to the SD card! Unfortunately, I still can not find the button for logging data to the SD card in the WaveForms Live. Only 'chart' is available. My firmware is already the newest version 0.1719.0.
  9. I've noticed some problems with openlogger and waveforms live: 1. If I try to enter a equation into the analogue channel scaling popup, I cannot enter "mV" for the units. It looks like entry is restricted to a single letter only. That is a bit limiting. Furthermore any scaling equations I enter there don't seem to be saved, so I can't reload them next time I start waveforms live 2. Under the Advanced section, if I save the profile its not there the next time I run waveforms live. Where is it saved to, and how do I retrieve a stored profile?
