I just had a quick look on how to send/get a report.
You need to do a controltransfer.
I you look at: function TJvHidDevice.GetDeviceString(Idx: Byte): string;
You will find an example on how to do a controltransfer.
It could give you a start.
thanks , that is a help. I will investigate.
I would be thankful if I can ask you (many) more.
thanks
PS: One more question:
Would this be a way to make the prg debugable?
My Device is connected to the ANdroid usb OTG. So I can not debug via Delphi and the device is connected.
So My idea:
Wo make the same way with WIN
API with the control transfer, as my device can be connected to WINDOWS and so
I can debug the prg too.
When It works on win I copy it to my Android program.
Would this a way to start the investigation?
I tried: But I do not get an aquivalent function in the WIN
API (Hid.dll) for
Code:
FUsbDeviceConnection.controlTransfer
.
How can I make a controltransfer with win
api wihtout using the ready made GEt_Report.
Any ideas?
Thanks
