K8055 DLL Question

Having just started to look at the K8055 and the supplied DLL, I realised that the only documented calls are to read and write to the device…

As I intend to use it to detect a user pressing a key I would have to scan the digital inputs at a fairly high frequency!

Does anybody know of a way to have the K8055 signal the digital change event, so I can avoid loading my PC with yet another loop?

Thanks,

Richard Gamester

There is the link: AREMBEUSB ActiveX Control arembe.com/

There is written:
[color=#004000]“An Excel workbook shows how to use the AREMBEUSB control to implement a data logger, which records the status of the five digital and two analog inputs to the board. Data can be taken as a function of time, or as trigger events occur.” [/color]

Many thanks for your help, greatly appreciated!
