Hello,

The source code of streamer application (Streamer.h) is written in such a way that it fills the entire buffer with EFs. You can find the source code in the following location:

C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\application\cpp\streamer

Note: The path depends on your installation directory.

The screenshot of the same is given below:

For sending customized data, please make use of control center application as mentioned in my previous reply.

Best Regards,

Hello,

Streamer application just transfers some random data to check the throughput of the device. In order to send your own data, please make use of the application Control Center that comes along with FX3 SDK. After programming FX3 with the STREAM_OUT.img, please send the data as shown in the following figure:

Or you can just send a file by using Transfer File-OUT option. You can use the TEST.txt file which comes along with the AN65974 project.

Hi JayaKrishna,

If it is random data, how am I getting same data (EF) always? I think there should be a parameter to which data needs to assigned .
