Perform the following steps to install the sensor driver via Device Manager. Perform the following tasks to turn on testsigning. Load the compiled file into battery-backed RAM by entering the following command:īefore you install the sample sensor driver, you must turn on testsigning. You should see the ssdt.aml file listed in the tools directory. Verify that the compiled file was successfully created in Step 3 by entering the following command: In the Command prompt window, use the dir command to make sure that you can see the default file now listed as ssdt-old.asl, and the new file listed as ssdt.asl.Ĭompile the ssdt.asl file into a format that the Sharks Cove can understand by entering the following command: In the File name box, type ssdt.asl, then select Save, and close Notepad. Then select the Save as type dropdown box, and select All Files. I2CSerialBus(0x53, ControllerInitiated, 400000,ĪddressingMode7Bit, "\\_SB.I2C3", 0, ResourceConsumer) OperationRegion(ABLK, SystemMemory, CPTR, 0x10) So make sure that the button cell (battery) that came with your Sharks Cove is plugged into its socket.Ĭopy the following updated SSDT and paste it into a new instance of Notepad. The updated SSDT will be stored in a potion of memory called battery-backed RAM.

Perform the following tasks to update the SSDT, and load it to replace the factory default version. Then use the dir command to make sure that the file is now listed as ssdt-old.asl. Then enter the following command in the Command prompt window, to rename the ssdt.asl file. Review the ASL file, and notice that there are no references to the accelerometer, or the I2C bus.Ĭlose Notepad. Open the ASL file in Notepad by entering the following command: Make sure that the ASL file was created successfully by entering the following command: Invoke the ASL compiler and create an ASL file by entering the following command: Make sure that the Asl.exe file is listed in the directory. Open a Command prompt window as an administrator, and enter the following commands: Then Attach the flash drive to the Sharks Cove's USB hub, and copy the Asl.exe file to the Tools folder. On the Sharks Cove, create a Tools folder in the root directory. On your development computer, navigate to the following location to copy the ASL compiler:Ĭ:\Program Files (x86)\Windows Kits\10\Tools\x86\ACPIVerifyĬopy the Asl.exe file, and save it to a flash drive.

You will also learn how to replace the default SSDT with an updated one. This section shows you how to use the ACPI Source Language (ASL) compiler to retrieve the factory default SSDT for the Sharks Cove, and then review it. Before you beginīefore you start performing the tasks outlined below, please make sure that your Sharks Cove is set up as shown in the following image: This table describes the hardware resources and interrupt requirements for a hardware platform's devices, including attached peripherals like the accelerometer. To make the Sharks Cove's ACPI driver aware of the new device (the accelerometer) on the I2C bus, you must add information about the accelerometer to the SSDT on the Sharks Cove. So the sample driver for the accelerometer was developed to support ACPI instead of Plug and Play.
Peripherals that are connected to the I2C bus are enumerated via the Advanced Configuration and Power Interface (ACPI). The accelerometer is attached to the Sharks Cove via the I2C bus.

For more information about how to do that, see Download kits and tools for Windows 10, and follow the instructions to install Windows 10.Īfter you finish installing the operating system on the Sharks Cove, See Build the sensor driver to learn how to build a driver in Microsoft Visual Studio. So if you want to perform the tasks presented in this topic, you must first install an operating system on the Sharks Cove. This topic uses the Sharks Cove development board and an ADX元45 accelerometer as a case study, to help explain the process of installing a sensor driver on a development board.
This topic shows you how to install the sensor driver on a development board, after you update the secondary system description table (SSDT) for the development board.
