I want to read/write the high/low of GPIO pins of Intel Atom c3558 in Windows driver code. I have found some information about GPIO MMIO access for in the datasheet. But I don't have enough background knowledge to understand it clearly. So I wonder if there is a complete example of GPIO MMIO access, including how to set control registers and where to the high/low of pins.
Thanks!

Hello, @LW000:
Thank you for contacting Intel Embedded Community.
Could you please clarify if the design related to this thread has been developed by you or by a third-party company? In case that it is a third-party implementation please give us the part number. model, manufacturer name , and where is stated the information related to it.
Waiting for your clarification.
Best regards,

It is a design of our own company. The IoT OS we use is Windows 10 Enterprise LTSC 10.0.17763. The CPU is Intel Atom C3558. We want to read the level(high/low) of some GPIO pins. The GPIO controller driver from Intel (iagpio.sys) which installed with OS didn't work. So we plan to develop a Windows driver to access GPIO via MMIO. Since we have no experience with it, we are looking for sample codes for it.
Thanks!

Hello, @LW000 :
Thanks for your reply.
It is important to let you know that the reference code is only provide to BIOS vendor. Due to this fact, in order to have access to the BIOS reference code you should contact your Intel Bios Vendor (IBV).
