Looking for a EG20T GPIO working sample code in Windows XP

[EShem1]

Hi,

I'm trying to work with the Intel driver for EG20T GPIO under Windows XP embedded.

The programmer's manual for the driver is not very helpful and I was not able to find anything online.

I'm trying to operate the GPIO part of the device using the driver.

Does anyone have a working code sample I can use?

Thanks,

Ely

Leon, I'm still waiting for a code sample or clarifications to the documentation (which is very unclear) so I can use the driver.

Hello Ely,

I can only find this guide you've mentioned along with the .h files from the drivers.

Another is https://www-ssl.intel.com/content/www/us/en/secure/intelligent-systems/privileged/eg20t-sample-reference-code.html?wapkw=eg20t Intel® Platform Controller Hub EG20T: Sample Test Program.

Done. Thanks!

Leon,

This is taking too long (and is over complicated for what I need).

Couldn't you just copy and send over the sample code?

I am already several weeks behind on this...

Hello Ely,

My apologies for any inconvenience caused. I'm unable to simply copy and send it over to you.

I have already made a follow up regarding your application for a privileged account.

Got it Lynn. Thanks...

I tried out the sample code from that link, and I'm getting linking errors:

1>gpio_sample.obj : error LNK2001: unresolved external symbol __imp__SetupDiGetClassDevsA@16

1>gpio_sample.obj : error LNK2001: unresolved external symbol __imp__SetupDiDestroyDeviceInfoList@4

1>gpio_sample.obj : error LNK2001: unresolved external symbol __imp__SetupDiGetDeviceInterfaceDetailA@24

1>gpio_sample.obj : error LNK2001: unresolved external symbol __imp__SetupDiEnumDeviceInterfaces@20

I'm using Visual Studio 2008 on Windows XP SP3.

Any ideas?

Hello, Ely! It looks like you may now access Intel Confidential content. Michal should be able to assist you as well. LynnZ.

[EShem1]

I found the missing library and the sample code is working.

I am struggling to combine it with my application: the sample code is using ANSI and my application is compiled for UNICODE.

Any chance you have sample code that compiles for UNICODE?

Latest update

I was able to get this working... Thanks...
