    The Software InnoMakerSetups.msi has only Text in China look.

  4. Do you mean this file for windows?

    You need to download it and rename it as .msi if your computer block it.

    Hello. Do you have a schematic or pinout for this? I see that you have the I2C exported on the board.

    1. Sorry we don't provide sch for this module. We will launched another version which will provide.

    We have inno usbtocan device. We are trying to develop a Java application to receive and send CAN Messages thru usbttocan. Could you help us in how to start with it. I am using InnoMakerUsb2CanLib.dll but calling getInnoMakerDeviceCount() but then it gives me an error

    Error looking up function 'getInnoMakerDeviceCount': The specified procedure could not be found.

  7. Could you send me email including more information of your project? And what you need from us  like the source code of the dll?

    Could you please provide a link to sample code how to implement in c/c++ winapi? As previously mentioned the supplied DLL does not expose any function entry points. At least a small hint for how to access the device would be great. And same here: The installer (msi-file) seems to have chinese localization only (or at least any fancy writings).

    1. Hi, it may takes us one more week workload. Please wait and keep in contact with us
