DRV8842: Fault recover automatic

DRV8842: CPG005_DRV88xx Evaluation Module

Part Number: DRV8842

Hello:

I purchased a CPG005_DRV88xx Evaluation Module. When install its EVM software, it shows in its "Getting Started with the EVM application" installation instruction for Windows XP and Windows 7. Is there any new version of installation software for windows 10 since my computer is new purchased and windows 10 was installed as default? Thanks.

    Hi Yiping,

    There is no new version. The software works in Windows 10.

    It is recommended to use compatibility mode as described for Windows 7.

    Thanks, One more question is about to use this GUI software, everytime when I change a parameter, like voltage OR PWM control, it always prompt me small window "NO COM PORT OPEN" even thoung it connects to the COMS actually from "device management" of windows. Is anything wrong with this prompt window? See the attached.

    Hi Yiping,

    Please confirm you have selected the correct COM port in the pulldown menu and then pressed the CONNECT button on the GUI.

    This is described in section 3.1 of the User Guide.

    If you have done this, please provide a screen capture of the device manager showing the COM PORTs and the screen capture of the GUI when it is not working.

    Thanks Rick:

    When I opened the GUI, at lower left hand side, a small box shows "Disconnected". Next to this box, it shows COM4 for example. When I click the Settings Tag on the top, it shows a COM4 port "checked" and it matchs the USB port on the device window of WINDOWS. So I think it maybe has some jumpers I have to set for operation.

    Could you tell me where can I found the schematic diagram of this EVM? I have only found the EVM user's guide (SLVU410) from TI website. I can follow the instructions on the UG, But schematic diagram may give more help.

    Thank you very much for help.

    Hi Yiping,


    You do not need to change jumper on the device to communicate. I will locate the schematic and send it to you. Can you provide the markings on your PCB (CPG???, REV??, DATE is ??/??/??).

    If you tried to install the USB driver in the software file, please remove it. That driver is old and has been updated.

    Please go to the FTDI site and download the latest driver for the FT232RL. The link is www.ftdichip.com/.../VCP.htm

    My PCB is CPG005, REV A 02/09/2011. I have my driver successfully installed. The problem is caused by company's security firewall and network.
    I have our IT department to re-authorize my computer to be Admin. Then installation is OK. But I still need the schematic if you can help me to get it. Thanks.

    Hi Yiping,

    Please see attached file:

    CPG005_SCH.PDF

    This appears to be the correct file, though I have not been able to confirm it. If it is not, please let us know. We are approaching a holiday and may not respond until next week.
