TMS320F28375D: Displaying the triangular wave carrier and sine wave signal with CCS's graph function

Hello,

Do we have any documents or training materials about this application?

There is generic documentation for th CCS graph tools:

https://software-dl.ti.com/ccs/esd/documents/users_guide/ccs_debug-graphs.html

All the functionality and graph properties are mentioned in this chapter of the User's Guide.

Since the customer is using F28x, I want to mention on limitation of the graph tools since may people have certain expectations for it. As the end of section 7.7.1 mentions in a note:

Despite the resemblance, the graph utility cannot be equivalent to a high speed real-time oscilloscope, given the update rate through the Debug Probe and the latencies involved with the breakpoints can only reach as low as 0.1s under extremely ideal conditions. Also, the Sampling Rate is entirely arbitrary and does not reflect any peripherals configured on the target device.

In summary, consider the graph tool as a post-processing utility for signal analysis.

For devices with real-time memory access support (like 28x), there is another consideration. There is a limitation of the Graph view refresh rate (how often the graph can be updated in the view). It is defaulted to 0.5s. Lowering it can cause stability issues with the IDE.

Thanks
