LAUNCHXL-F28379D: serial communication/print out data to PuTTy through USB

Tom Liang

I did some ADC and store the data into an array. I want to use these data to plot a graph in Excel to see how well is the ADC.

I am stuck at getting this data. I checked SCI examples, but it didn't help much. I think there is simple way like printf.

So I wonder if I can use printf to show the data on PuTTy. If so, do I have to configure UART/SCI? What is the default baud rate for F28379D?

I am also open to other solutions for measuring how fast is the ADC and getting data.

Regards,

Tom

Hi Tom.

Another poster was inquiring about a data log / graph feature that one can access through code composer.

There is a snapshot of a graph in the thread.

There is also the GUI composer which I don't have any experience with but perhaps you can use it to pull a data array out of the device via JTAG.

Thanks so much. I didn't know that the graph function in the debug mode can plot an array.

Hi Tom,

For debug purposes you can use the graphing tool in CCS as Programmable Solution suggested. Another easy method is to view an array of samples in the memory browser, then save the results to a file, then open the file and paste the results into excel.

If you want to scan data in/out in your end system, SCI/RS-232, USB, or JTAG are the ways to go. With JTAG search for "DSS" or "Debug Server Scripting" to see how to programatically get data in/out of the device via JTAG.
