TMS320F28379D: USB Read of fifo.

Anil Singhal

Part Number: TMS320F28379D

I have configured USB as a bulk end point with a maximum size of 64 bytes. Let's say I receive 10 bytes but for efficiency sake (using RPTB), can I read 64 bytes anyway or I must only read 10 bytes?

Hi Anil,

I think you can read 64 bytes. I will get back to you with more details.

Thanks and Regards

Anil,

You read 64 times from the FIFO. However, if you reading them into a USB Buffer, you will need to manage the buffer pointers accordingly. If you are not using a USB Buffer, then it shouldn't effect anything.
