Hi everybody,
I�ve got a Cypress Developers Kit 3650
with a modified Firmware from Jan Axelson
The only thing i have is a Visual Basic Script
which can send Data to the Device.
Here is the Source:
'Data to transmit
OutputReportData(0) = &HA
OutputReportData(1) = &H0
Private Sub WriteReport()
'Send data to the device.
Dim Count As Integer
Dim NumberOfBytesRead As Long
Dim NumberOfBytesToSend As Long
Dim NumberOfBytesWritten As Long
Dim ReadBuffer() As Byte
Dim SendBuffer() As Byte
'The SendBuffer array begins at 0, so subtract 1 from the number of bytes.
ReDim SendBuffer(Capabilities.OutputReportByteLength - 1)
'******************************************************
'WriteFile
'Sends a report to the device.
'Returns: success or failure.
'Requires: the handle returned by CreateFile and
'The output report byte length returned by HidP_GetCaps
'******************************************************
'The first byte is the Report ID
SendBuffer(0) = 0
'The next bytes are data
For Count = 1 To Capabilities.OutputReportByteLength - 1
SendBuffer(Count) = OutputReportData(Count - 1)
Next Count
NumberOfBytesWritten = 0
Result = WriteFile _
(HidDevice, _
SendBuffer(0), _
CLng(Capabilities.OutputReportByteLength), _
NumberOfBytesWritten, _
0)
I even don�t know what kind of transfer it is. But i think its
a Control message.
Now i�ve to program the writing and reading from the device under Linux. Can
you give me any clues or
information how i can handle this?
Any good link/documentation welcome.
Hendrik
