CCS/TMS320F280049: Look for a tool for the faster variable refresh rate

Part Number: TMS320F280049
Other Parts Discussed in Thread: LAUNCHXL-F280049C, ENERGIA

Tool/software: Code Composer Studio

Hi Experts,

According to the e2e thread https://e2e.ti.com/support/microcontrollers/c2000/f/171/p/739373/2734670
it seems that the fastest refresh rate for the variables is 100ms.

Do we have any tools which supports faster refresh rate?
Moreover, if there are any 3rd party's tools available, could you please let me know.

Thank you in advance for your time to check.
Best regards,
Hitoshi

    The only possibility is outside of Code Composer Studio. We have Gui Composer that allows creating full custom graphical interfaces with interaction with the hardware. The communication transport could be a UART port (there are some mmwave examples operating at 921600bps) given the overhead is pretty small, but you would need to create code on the target device to funnel the data to the serial port, either for the built-in XDS110 UART channel of the LAUNCHXL-F280049C or third party hardware tied to a serial port on the device.  

    The GUI Composer User's guide contains information about this functionality. You will want to look at the following sections:

    - Section 6.2 contains an example to transmit serial data from the target to the host. It uses Energia as a simpler way to format data in JSON format on the target device, but using a serial port example would have a similar effect. 

    - Section 3.2.1.3 contains details about the USB-UART transport mechanism, including the details about custom data format.

    I would start small, perhaps displaying the incoming data in a specific format (hex or decimal, for example) and then build up to a full graph with more controls over the target, etc. 

    Hope this helps,

    Rafael

  • Hi Rafeal,

    Thank you for suggesting the resolution.
    It helps us a lot.
