Error on PC Demo Source Code

[katoshuhei]

I want to make the PC software which read NTAG I2C plus device via Identive CLOUD 3700F. 

Then I download "NTAG I2C plus PC Demo application source code" (SW3650).

And I install Visual Studio (Community) 2017 and Windows SDK 8.1.

But it outputs error ("cannot open include file. 'ctype.h' no such file or directory.").

Could you advice me.

OS is Windows 7 Home Premium Service Pack 1.

I am friendly to gcc but not friendly to Visual Studio.

This problem is NOT solved yet. But I extract some codes from 'ProxAPI.h' and construct new program then I can read NTAG memory. Thanks to forum supporters. And I remark it for your reference.
