When I try to use I2c1 SDA pin (GPIO 2 BCM number) via GpioController::OpenPin() func, it compiles OK but it throws an exception HRESULT:0x80070490 Element not found.

How should I use I2c pins as any other gpio pin like GPIO 5 or 6 for example.

Note: Numbers above are BCM

  • I have no idea what GpioController does. It's not a standard C++ library. Where did you get it? Is it a library? – joan Jul 25 '15 at 12:58
  • @joan Forgot to mention, I'm using Microsoft Visual Universal App – Quest Jul 25 '15 at 13:00
  • So is this a Windows IoT application? – joan Jul 25 '15 at 13:01
  • @joan Yep it is - sorry for long reaction time – Quest Jul 25 '15 at 13:24

Assuming this is a Windows 10 IoT application.

At the moment it does not seem possible to use some gpios as gpios with Windows 10 IoT.

For instance I2C gpios (gpios 2 and 3) and the main SPI gpios (gpios 7, 8, 9, 10, and 11) may only be used for I2C and SPI respectively.

I have not seen any official announcement, perhaps raise a question on https://social.msdn.microsoft.com/forums/en-US/home?forum=WindowsIoT

  • Do you have any information if this "feature" will be avalible in later builds? – Quest Jul 25 '15 at 13:27
  • I simply don't know. If I was you I'd raise the question on the forum I linked, firstly to check what I've said is correct, and, secondly, to show the feature would be of use. – joan Jul 25 '15 at 13:30
  • I've already did. I just wanted to make sure you aren't aware of any possibilities. – Quest Jul 25 '15 at 13:35
