CCS v5 tms320f2803X example code

Other Parts Discussed in Thread: TMS320F28035, CONTROLSUITE

Hi,

I'm using CCS v5 and control SUITE example code to get me started developing code for the tms320f28035. I'm a little confused about the generated .c files once the project is built. Specifically the DSP2803X_DefaultIsr.c. I'm assuming this is where I would write my interrupts e.g. SCI interrupt handler (__interrupt void SCIRXINTA_ISR(void) ). Am I free to write my interrupts in this file or is this an automatically generated .c file that is generated only if i don't implement my own DSP2803X_DefaultIsr.c in my project space ? Any help is greatly appreciated

Thank you

Mario,

DSP2803x_DefaultIIsr.c is just an example file. It is NOT auto-generated. Rather, it is part of the peripheral header file examples, under the 'common' folder (the file is common to all the examples). There is only one copy of it in ControlSuite.

You can modify the file if you want to put your own ISRs in there, but you want to be careful about editing the only copy of the file. You might want to make a local copy of it for your own project. If you want a portable starter example (one that is not tied to the ControlSuite files), download the files for appnote SPRA958.

Thank you,

Would adding a local copy to my project space keep the builder from referencing the one in common?

Completely unrelated question but are there any microcontrollers that support interfacing with USB peripherals ?

I'd expect so. Try it, and confirm that the file is the local copy before you save any edits.

There are many. Try using the selection tool:

Hi,

I'm also working on TMS320f28035. Did you face any issues while configuring TX FIFO interrupts?
