Part Number: TMS320F28379D

Hi,

How many fast the max speed of the CDC device class transfer?

What should I set to increase the transfer speed?

How can I keep sending data like usb_ex9_dev_bulk_throughput?

Thanks in advance.

Hi,

The usb_dev_serial example uses bulk endpoints. In case of usb_dev_serial example, the host PC only sends two IN packets requesting data from the device per frame (1ms). This is a maximum of 128 bytes / ms.

The examples uses interrupt to handle the transfer of data (receive and send) . If you have to send data continuously, you will have to update the code to call "USBSCIPrimeTransmit()" function by checking the status of the SCI flags instead of interrupts.

Best Regards

Siddharth
