TMS320F28375D: USB speed of C2000ware example

Lenio Cacula

Part Number: TMS320F28375D
Other Parts Discussed in Thread: C2000WARE

It seems the USB CDC examples in C2000ware run at a rate of 2Mbps. Is it possible to modify them to run at full speed, 12Mbps? Can you offer details?

Thank you!

Hi Lenio,

The throughput is limited by the host requesting data (by sending DATA IN packets).

We have been able to achieve 7-8Mbps using the bulk example and a Visual Studio host application. But we also found that the limiting factor, or the bottleneck was the Windows machine (the host).

Hope this helps.
