USB-serial support for ezDSP C5505 USB stick

Other Parts Discussed in Thread: SPRC133

Hi,

I want to send sampled data from my ezDSP C5505 USB stick to PC using virtual COM (UART). Yet most examples of such operation are for C5535 or other types. Also some sources say such operation is not supported for this board. So...

1) is it supported?

2) if 1) is true, I'd love to some example code of how it is done.

Thanks,

Martynas

    Hi Martynas,

    1. On the C5505 USB stick, it is possible to send data through the XDS100 -  USB to UART virtual COM port on Channel B (FTDI chip).

    2. You can try the UART examples present in C5505 CSL package to send data through virtual COM port. Please visit the following link to download the latest CSL package:

    Hope this helps.

    Hi,

    I have tied the CSL_UART_IntExample on to my ezDSP board. When debugging, in UART_fputs function I get warning message "cannot load from non-primitive location" - what could be the source of that?

    When the program was loaded I could not get any data through using terminal software. Tried it on HyperTerminal and PuTTY - same outcome.

    Any suggestions on why it is so?

    By the way, I found this article http://www.element14.com/community/thread/4269 and it appears to me that

    some soldering is needed to make it work. Am I missing something?

    Regards,
