Enable USB Virtual Com Port with Beestack and KW24

alejandrovelez — Wed, 07 Oct 2015 17:17:33 GMT

Good Afternoon:

I am trying to configure the virtual com port application with the Beestack and the KW24 Processor with no results.

I initialize these modules in the BeeAppInit.c file:

USB_Init();

(void)CDC_ModuleInit();

and define the variable:

#ifndef gVirtualCOMPort_d

#define gVirtualCOMPort_d TRUE

#endif

in CDC_Interface.h file

then I try to send a string to the virtual com with the function:

bool_t CDC_Transmit(unsigned char const *pBuf, index_t bufLen, void (*pfCallBack)(unsigned char const *pBuf))

the application runs, but when I connect the device to the computer the system doesn't recognize it, and I get this error from device manager:

How could I solve this problem?

or there are an example with USB-CDC in BeeStack?

I'm working with BeeKit and IAR Embedded Workbench

Thanks!

Hi Alejandro,

I had same problem and succeeded to resolve.

You need to install Windows driver for Freescale Kinetis product.

You can find the cdc.inf file enclosed in the followinf thread.

Fabrice.
