Virtual com port driver for C55 onboard USB.

Is there any driver s/w that can turn the onboard USB interface in the C55 family into a virtual com port?

One could then use that USB interface to communicate in 'asynchronous' mode with a host over USB.

    Hi Ross,

    I only dabble with the C55xx line, but it is my understanding that we have a 32-bit CDC ACM driver in the Chip Support Library (http://processors.wiki.ti.com/index.php/C5000_Chip_Support_Library#Documentation). This CSL version is 3.00.

    Once the CSL is installed, I believe the driver file can be found in: ...\c55xx_csl_3.00\ccs_v4.0_examples\usb\CSL_USB_CdcExample\C5515_CDC_ACM.inf. Check the example code in this directory too! I do not know what c55xx chip you are working with, so please note in the example *.c file comments which chip versions the code does or does not work with.

     

    I hope that helps!
