Respected sir

Tried the dos promt test
from xillybus_getting_started_windows.pdf

first dos window
> streamread \\.\xillybus_read_8

second dos window
> streamwrite \\.\xillybus_write_8 AA
(Now type some text on the second DOS window, and press enter)

message appeared

"usage:streamwrite devfile"

no data appeared on first dos window

kindly let me know where is the mistake

regards

Hello,

As the "usage" message says (and the guide) you should go

Code: Select all
streamwrite \\.\xillybus_write_8


and nothing added after that. The "AA" part is a second argument which streamwrite rejected.

respected sir,

Thanks for continued support and help . It is now possible to send data to FPGA using \\.\xillybus_write_8 device.
The device accepts 128 bytes at one go. The requirement is to send a digital video file from PC to FPGA.continuously.
Kindly advice how to go around. Any example will be appreciated.

Hello,

In order to achieve higher rates, I suggest using a buffer of 32 kBytes or so instead of the example's 128 bytes. Instead of allocating the buffer as an array, use malloc to a pointer instead.

For more information and hints, please refer to the Xillybus host application programming guide for Windows, which is available at the website.

Regards,
Eli
