I'm trying to get USB CDC working full duplex on TWR_KW24D512
I have built my prooject with beekit release 3.0.2, HaOnOffSwitch_EndDevice.
I can send and received data on UART1 (TWR_KW24 <--> Teraterm)
I have included the files needed to support USB CDC and added initialisation calls as follow:
in BeeAppInit.c void Main()
// Initializes USB vitual COM port //
#endif // #if gVirtualCOMPort_d
in BeeApp.c (void BeeAppIni (void))
// USB data log and Command Port Rx CallBack Setting
I can send without any problem logs to tera term window calling:
CDC_Transmit(pBuf, bufLen, pfCallBack)
There is a problem on USB CDC RX side:
BS_SerialRxCallback function, is not called everytime data are sent from teraterm to TWR-KW24.
It is called only two times and no more.
First data frame is not seen
second data frame is not seen
third data frame is not seen
Forth data frame is properly received
5th data frame is not seen
6th data frame is not seen
7th data frame is not seen
9th data frame is not seen
10th data frame is properly received
All following frames are not seen!!!??
What can be the rout cause of this behavior?
Thank you for your support
