Accessing I2C devices on PUC DE3815TYBE and Windows-10



I have a new PUC DE3815TYBE board.

I installed Windows-10 on it (I am planning on using embedded/real-time Windows or Linux in the future).

I installed the PROC_IO_Win8.1_32 device drivers for the chipset: I2C, GPIO, USART, ...

The Microsoft I2C HID Miniport Driver hidi2c is Stopped.

The I2C Controller Service iaioi2c is Running OK.

The Intel(R) Serial IO I2C Controller Driver iaLPSSi_I2C is Stopped.

Under Device Manager, I have two instances of I2C Controller devices under System Devices:

Manufacturer: Intel Corp.

Location: on Microsoft ACPI-Compliant System

Status: These devices work properly.

Device Instance Paths: ACPI\80860F41\1 and \2


Devices installed: iaioi2ce.inf

Devices configured: oem6.inf

Devices started: iaioc2c

Devices configured: oem12.inf

Devices installed: iaioi2ce.inf

Status: 0x0.

I downloaded the Intel(R) Platform Controller Hub EG20T Intel Integrated Circuit (I2C) Driver for Windows Programmer's Guide which is not quite for my platform, but I hope it to be close enough.



1) I do NOT have the files referred to by this document on page 8:

ioh_I2C_ioctls.h, and


I NEED these files in order to write my application program!

2) I tried to call the win32 function CreateFile(), but I do not know the name of the I2C device!

Can someone please help?

Thank you,
