Do you know a USB component for Delphi 6 ? I want to perform a communication between a microcontroller with USB and a computer.,

Thanks

Paulo

Are you asking about a topic related to our IO-Warrior chips, or is this a general programming question for some chip you are developing yourself?

If the second is the case then please ask in some general programming forum.

There is no general purpose component possible.
Only the HID subclass of USB is accessible through my HID component which is also enclosed in the IOWKIT SDK.

Most classes of USB devices have a class driver in the common OSes.
Usually the device is then accessed through an API which is not USB specific at all.
An USB stick for example is a mass storage device and is accessed through the normal file system API aka file access.

Hello,

we have a toolkit RapidDriver, intended especially for that purposes. You can download it at:

Hello...

Hi Robert,

Thanks for your HID component.
I have been using the component for 2 months.
Now, i want to read/write FEATURE reports, but no success... :(
Could you help me?

Thanks a lot.

Best Regards,
mirza

Use the SetFeature method. It works about the same as the WriteFile method.
The parameters are the report and the size of the report in bytes.
The feature report itself has of course to be declared in the report descriptor of the device.

I definitely know that it works. The KeyWarrior chips use a feature report to write the key table. The table writer app uses of course the HID component.
