问题
I am attempting to create a hardware device that sends data to the windows phone via headphone audio jack.
I have researched this and found that the Core.Audio api on the msdn site offers what I need however I don't think / cant find this in the windows phone API's
Is this available to developers?
Obviously someone has access to this because I have seen some companies use it for credit card processors.
回答1:
The audio APIs you'd need to do this are not included in the standard Windows Phone 8 SDK.
Other apps that are using functionality like this must be using other 3rdy party libraries or have [re]written the functionality themselves.
