BqGaugeStudio and BqCONFIG not worked with EV2300??

Other Parts Discussed in Thread: BQ27425-G2A, BQEVSW, EV2400, BQ27531EVM

Dear Sir,

I need to review status table of gauge IC bq27425-G2A and I had a problem when working with EV2300 tool (PCB : HPA002 rev B).

I downloaded 3 application tools from website page for product bq27425-g2a : bqEVSW-bq27425g2 v2.05 , bq GaugeStudio v1.0.2 and bqCONFIG v1.5.2.

I used one tool at one time and double checked no other application activated with windows task manager. 

EV2300 worked well with bqEVSW, however it 's not worked when open  bq GaugeStudio v1.0.2 (hit : no adapter or gauge found) and bqCONFIG v1.5.2 (reading fail).

The pictures of screen shot are below.  Please kindly help me.....

  • Hi all,

    I am seeing a similar issue using the EV2300. The EV2300 appears in the Gauge Dashboard for 2 seconds and disappears for 1 second, repeatedly.

    I have downloaded and installed the 64 bit drivers for the EV2300. Currently using Windows 8.

    Please advise.

  • Also seeing this connection error from bqCONFIG program:

  • Hi Bryan,

    The 64 bit drivers for the EV2300 doesn't work with windows 8. You will have to downgrade to or use a computer operating on  either windows 7 or xp

     

    thanks

  • Onyx,

    Thanks for the fast reply. Let me install on 7 or XP and see if it works.

    Bryan

  • Onyx,

    I see the same behavior on a 64-bit Windows 7 machine, but it seems to work on 32-bit Windows XP.

  • Hi Bryan

    For your 64 bit win 7 computer, install as an administrator  the drivers from this link below. I use a 64 bit window 7 and the device works just fine.

     If you still have issues, then simply stick with XP :)

    thanks

    Onyx

  • Hi Onyx,

    I ordered a new EVM and tried again. I have three different EV2300 units and I see the same results with all three. In GaugeStudio:

    Win XP 32: EV2300a icon lights up and stays lit, but no connection to gas gauge.

    Win 8 64: EV2300a icon lights up for 2 seconds, turns off for 4 seconds. No connection to gas gauge.

    I also tried Compatibility Modes in Windows 8 (XP/Vista/7) and I see the same issue.

    Please see how you can help.

    Thanks,

    Bryan

  • Should we use EV2400 instead of EV2300?

    This error message shows up in the bottom left corner of the GUI when I plug the I2C cable into the EV2300:

  • Hi Bryan,

    The guage studio is a product of the handheld team.  I will see if someone can address your problem.

     

    thanks

    Onyx

  • Hello Bryan,

    We have been trying to duplicate this issue on our systems, but have been unsuccesfful at capturing this failure.  At the moment we believe there might be some timing issues with the EV2300 and the new software that is coming out.  So, at the moment we have to suggest using an EV2400 instead of the EV2300.

  • Jared,

    Good to hear from you, thanks for the reply.

    Is there any way to factory-reset or reflash the EV2300 boxes? Perhaps we changed the FW somehow in previous evaluation.

    Also - I am seeing some communication on the I2C lines when I open GaugeStudio. There's about 3 seconds between each packet. When GS is closed, the I2C comm stops. SDA/SCL are pulled up to 2.5V on the bq27531EVM.

    I recorded about 40 seconds of data but it keeps going forever. Each packet seems to be different but I haven't decoded it. Log file is attached, please download Logic software (free) from Saleae. It is easy to navigate.

    Hopefully this will give you more clues.

    Thanks

  • Hello Bryan,

    I will pass this information along to our tools team.  Hopefully they can provide some insight. 

    Since you are checking out the bq27531, I would recommend just using bqEVSW (it is also in the '531 product folder).  That should allow you to keep the evaluation process moving.

  • Thanks Jared.

    I notice there is an unpopulated 10-pin connector on the bq27531EVM that looks like it could be for the gray TI USB Interface Adapter box. Is this an alternative way of talking with the EVM?

  • Hi all,

    GaugeStudio works perfectly well with the EV2400 box. Problem solved on my end.

    Thanks,

    Bryan
