Need help in F2833x library files

Other Parts Discussed in Thread: CONTROLSUITE

I have started to learn about F28335 DSP and I am using controlcard holding the same processor.

In my project, along with the requirement specific source files, I am using many TI provided library files, and one among

them is the file "DSP2833x_DefaultIsr.c". I am supposed to perform a unit testing of this file. Hence needed a help on this.

I need to know whether by changing the bits of the Interrupt enable/flag, can we able to induce the corresponding interrupt? If yes what kind of register do I need to modify during the flow, so that I can induce each interrupt and perform the unit testing.

    Hi Sai,

    Actually "DSP2833x_DefaultIsr.c" contains only the interrupt routines. Enabling and disabling the interrupts are usually done in main.c by the user.

    Hi Gautam,

    Thanks for the response.


    Actually I am in initial stage of learning about the processor. I need to know how that kind of interrupts can be invoked, so that the I can write some user-defined code in that interrupt routine and verify that each function.

    That's a nice question. I hope you've already downloaded controlSuite, if not then please do. I would like you to go through "external_interrupt" example present in folder:

    C:\ti\controlSUITE\device_support\f2833x\v133\DSP2833x_examples_ccsv4

    Also, do refer the userguide "System Control and Interrupts" - Literature Number: SPRUFB0D

    All your doubts would be cleared instantly. Still if you've some, don't hesitate to ask.

    Regards,

    Gautam
