[Stephane]

Hi all,

I have an few question for building an PowerBasic application for read and write data from the USB port with the mpusbapi.dll.

1) Wat are the important programming steps for using this mpusbapi.dll?.

2) Can someone help me how I can written my first program to control the mpusbapi.dll?

Kind regards
Stephane

I don't recommend mpusbapi.dll for new design. Instead, apply WinUSB.dll directly.

As Microchip wrote in their announcement (*1), current version of mpusbapi.dll is a wrapper DLL over WinUSB.dll. They provide this DLL for painless migration from former versions, when they have decided to deprecate their custom PC driver, mchpusb(64).sys, and moved to WinUSB. If you would have many examples on mpusbapi.dll to start with, you might have good reason to use this DLL.

Jan has an excellent VB example for WinUSB on her WinUSB page.
