Transmit Complete Flag in Freescale Kinetis USB Stack 4.1.1

punitkumar — Fri, 12 Feb 2016 13:24:58 GMT

I'm using Kinetis K64 MCU with Freescale USB Stack 4.1.1 (CDC).

My application need some flag from USB stack which shows that the data i submitted have sent completely.

Actually i have a queue for data needed to be sent (packet by packet) and with good speed efficiency, i need sent confirmation flag so that i can submit next data to stack for sending.

Thanks in advance

NXP provides the KSDK V2.0 software, which includes USB Stack for K64 product.

And there also with USB Stack V5.0 for K64 product.

I checked the USB Stack V5.0 CDC device demo, which call USB_Class_CDC_Send_Data() function to transmit 64 bytes data.

Customer could set flag variable at Virtual_Com_App() function of <virtual_com.c> file to check if the data was transmitted.

Customer could check detailed application code info at default path:

C:\Freescale\Freescale_BM_USB_Stack_v5.0\Src\example\device\cdc\virtual_com\bm\iar\dev_cdc_virtual_com_frdmk64f

Wish it helps

Have a great day,
