I have questions about HID over I2C
« on: September 16, 2014, 03:18:35 am »
Dear All.

I has developing to communicate HID over I2C between Host to Device.
You can see detail as bellow link about HID over I2C spec.
http://msdn.microsoft.com/en-us/library/windows/hardware/jj127208(v=vs.85).aspx

I have experience HID over USB from your book(Jan Axelson's) and source example(VC6).
But no have experience about HID over I2C of interface.
First of all, I would like to read/write to device via HID over I2C. Please give me answer.

Q1) I know that the example code(Usbhidio_vc6) is base on HID over USB.
      If i use the example code(Usbhidio_vc6), Is it possible read/write to device via HID over I2C?
      - Usbhidio_vc6(Visual C++ 6) : http://janaxelson.com/hidpage.htm

Q2) The HID over I2C is recently mini driver at Windows 8 OS. If I try to access, I need any special code?

Q3) Please Let's me know, example code about HID over I2C. Such as Website or any paper.

Thank you.

This was news to me, interesting. It looks like the host application programming is the same. The device must return the expected ids using acpi as described in the documentation.
