I2cDevice class / Method WriteReadPartial issuing "unknown error"
Hello community, I'm currently working on an Intel Atom E39340 platform with Windows 10 IOT 2021 LTSC installed on it. The Read and Write methods of the I2cDevice class everything are working just fine. Nevertheless, one of my sensors needs a Write+Read access (Start / Write / Restart / Read /Stop) to access some registers. When I use the WriteRead(byte[] writebuffer, byte[] readbuffer) I get a System.Argument.Exception:'The parameter is incorrect'. (which is really weird because its compiling). When I use the WriteReadPartial(byte[] writebuffer, byte[] readbuffer) method to get the error code the result is 4 (i.e Unknown error). Overall, nothing happens on the I2C bus. I have explored the online documentation but can't find a lead... https://docs.microsoft.com/en-us/uwp/api/windows.devices.i2c.i2cdevice.writereadpartial?view=winrt-22621 Does anyone has ever experienced this ? Thanks a lot for your feedback. Best regards.Solved

Blank screen Skype user Windows 10 IoT
I recently installed MS IoT OS on a desktop PC and everything was fine until the last step in which it loads into the Skype user account and all I get a blank screen. I cannot log out (Ctrl+Alt+Del), Shift+Esc does not work either. I can hard boot but it automatically boots back into the local Skype user. Please help.SolvedPhil TukeySep 21, 2021Copper Contributor1.7KViews0likes2CommentsIoTEdge on Windows 10 IoT Enterprise
I have recovered some old electronics that were working very well with Windows 7 Embedded. Driven by the apparent simplicity of implementing IoTEdge in the documentation and understanding the great potential of joining IoTHub + IoTEdge I got down to work. After several hours wasted trying to configure a device, I must admit that I feel bewildered. During the process I try to install a clean copy of Windows 10 IoT Enterprise a total of three times by following the four steps outlined in: https://docs.microsoft.com/en-us/azure/iot-edge/how-to-install-iot-edge-windows but it was useless because I was not able to start the agent apparently due to not having permissions or because the docker agent cannot be started. I suppose that in the end I am leaving some nonsense but I don't know how to see it. Have any of you had a fight with IoTEdge / IoT Enterprise, or generally go directly to Debian based system?SolvedPepLluisBanoMar 29, 2020Copper Contributor1.8KViews1like3Comments
