CCS/DRV8301-HC-C2-KIT: memory issue

George Kochupurakal

Part Number: DRV8301-HC-C2-KIT

Tool/software: Code Composer Studio

I am working with project insta spin BLDC.

I have added extra code for some calculations to this project as a header file. There is around 25 variable array declarations. On compiling it shows memory error. What is the next step to do.

regards,

George

One option, if you're using a F2805x or F2806x, is to run the CTRL and EST modules out of ROM to save space in RAM. You can see an example of this using lab 2a. If you're using F2802x, you unfortunately will not have this option.

can I import the configuration to instaspin in HC_C2 Kit.

Also can I get the no of clock cycles for the execution of a module in the code.

There are InstaSPIN labs for the DRV8301-HC-C2-Kit in Motorware for F2802x, F2805x and F2806x Control Cards

Please see page 333 of the InstaSPIN User's Guide for cycle count considerations: www.ti.com/.../spruhj1g.pdf
