TMS320F28377D: Data visualization tool for C2000

Hi Bharath,

Can you share some additional deails about the NXP FreeMaster Recorder Feature? Did you use UART to export the variables out of the device? At what frequency did you export out at? What NXP device were you using?

We have something similar called the MCU Mission Control which is located in our SysConfig Tool. 

Best,

Ryan Ma

Data will be sampled at a fixed rate (e.g., 50 kHz) and stored in a static RAM buffer. Sampling can be triggered by either an internal or external event. The data will then be exported via JTAG or UART and visualized using the FreeMaster tool. FreeMaster is capable of processing the received data, as it is aware of both the sampling interval and the data type.

Hi Bharath,

Did NXP FreeMaster export data out of the device? Did you need to add to your application code some way to export the data you wanted to the tool?

Our current tool allows you to export data out of the device in some known format and to be visualized through a GUI within CCS. You can use UART as well.

Best,

Ryan Ma

Yes, FreeMaster provides middleware that manages the data within the MCU.

Could you please share the relevant links and documentation specific to the tools and techniques you're suggesting?

Hi Bharath,

We are soon to release an app note on these features.

I can walk you through on how to add this though for F2837xD. Are you using a Launchpad or ControlCARD? 

1. Create an empty_driverlib_project by importing from "C:\ti\c2000\C2000Ware_5_04_00_00\driverlib\f2837xd\examples\cpu1\empty_projects\"

2. Switch to Launchpad F2837xD by going to Devices icon, and switch

3. Add MCU Mission Control

4. Enable the custom export logger feature

5. If you're using the launchpad GPIO43 and GPIO42 should be connected to the XDS110 bridge (UART->USB).

6. Copy and paste the following code

// TITLE:  Transfer: Custom Logger Solution
//
//! \addtogroup driver_example_list
//! <h1> GUI based solution for data logging (one direction) </h1>
//!
//! This example demonstrates how to use SysConfig to enable datalogging
//! on our C28x devices. To enable this example, make sure to go to
//! Build -> Variables and set GUI_SUPPORT to value of 1.
//! This will create the GUI in CCS which can be opened under 
//! View -> GUI Composer -> Applications -> transfer_customlog_export_sci
//!
//! In this example, we are using SCI to export data out of the device.
//! If you're using a launchpad, you can enable board components to select
//! the correct SCI base to visualize the data through the COM port.

8. Build the project

9. Go to View -> Plugins -> transfer_customlog_export_sci

10. Load the .out, and you can view variables being displayed on the table that are being printed out. We also support logging arrays of values and buffering the values before exporting the data. You can refer to this folder path for other examples to port it over to F2837xD.

C:\ti\c2000\C2000Ware_5_04_00_00\driverlib\f2838x\examples\c28x\transfer

Let me know if you're able to see logs in the table.

Best,

Ryan Ma

Thank you for your detailed guidelines. 

I followed these steps, but in my IDE "View-> Plugin" option is not getting listed. I'm using CCS v20.1.1.8. Can you provide your thoughts? 

Try to reload your CCS view? Help -> Reload Window

BEst,

Ryan Ma

I did, it is not helping. 

Hi Bharath,

For the following post steps, did you make sure to update to your path? Apologize, I had not mentioned to update these since I am using ccs2010. Seems like you're using ccs2011?
