Whether is 'TIVAWARE' defined or not in an example project for LaunchPad?

Robert William

Hi,

I learn TI RTOS for Tiva-C TM1294 LaunchPad. I want to know more behind GPIO initial etc. When I read GPIOTiva.c, which is at the folder:

C:\ti\tirtos_tivac_2_14_00_10\packages\ti\drivers\gpio

I see the most part of the function 'static uint8_t getGpioIntIndex(PinConfig *config) ' is grayed out, as shown in the picture.

TM4C1294 is a Tiva device, but it looks like TIVAWARE is not defined in the editor. Yes, it may be defined somewhere in CCS project settings.

My question is: Whether is 'TIVAWARE' defined when I import the project 'gpiointerrupt_EK_TM4C1294XL_TI_TivaTM4C1294NCPDT' into CCS 6.1?

How can I know the real code (the grayed part or the #else part: return (config->port);)? The function is in binary library, which cannot be traced into.

Thanks,

The GPIOTiva.c code is part of the TI-RTOS driver library. When the driver library was built for TM4C devices, the TIVAWARE define was used. It looks like CCS is getting confused since the code is from a library. You should be able to step into the code. You may have to tell CCS where to find the file since the library was built on our Linux servers so the path name will be something weird (e.g. /db/vtree/zumaprod/...).

Hi, Todd:

I had check 'Verify Answer' several days ago. I don't know why I receive a reminding email for the post. Thank you for this and other high quality reply posts.
