undeclared functions in ControlSuite

Hi Shahbaz,

symbol not found errors like these are normally when the path to a library is missing.   Have a look at the wiki below.  Also, how did you work with control suite?   Have you tried an unmodified example?

Hi Lisa,

It's not a link error. The function is used but never declared, hence the warning saying it's implicitly declared.

In the meantime, I configured the project to project to just use the library already built in control suite and the build succeeds. Hopefully, I wouldn't run into issues since probably the library was also built with that particular functions "declared implicitly".

Hi,

Actually it turns out the i2c.c is not built into driverlib.lib. The header has all the functions (which apparently have an older prototype) commented out and the taking the declarations from the source (i2c.c) results in unresolved identifiers during link.

Can you please verify then that i2c is not implemented in v210 of the library for F2802x? If so, do you suggest I switch to an older version of the library or should I manually implement i2c functions not relying on controlSuite?

Hi Shahabz,

I suspect there is an 12C library you need but I am popping this over the the C2000/control suite team.

Hi Shahbaz!

I'm trying to start a project with CCS 5.5. I downloaded ControlSuite and figured out where the headers and libraries for my chip are. For reference, they were under ....\controlSUITE\device_support\f2802x\v210 (for the latest version).

I copied that folder over to my project and added its root to the include paths of the compiler. 

1 You don't need to copy all 210 folder to you project. You need just to include the following paths to you project through "Include options":

ti\controlSUITE\device_support\f2802x\v210\f2802x_common\include\

ti\controlSUITE\device_support\f2802x\v210\f2802x_headers\include\

Also add to you project the following source file:

F2802x_GlobalVariableDefs.c from ti\controlSUITE\device_support\f2802x\v210\f2802x_headers\source\

and for work with I2C: F2802x_I2C.c from ti\controlSUITE\device_support\f2802x\v210\f2802x_common\source\.

2 "I2C" is not mentioned in  F2802x-DRL-UG-210 (F2802x Peripheral Driver Library).

Hi Igor,

1. Thanks, I realized that and that's what I did (although I hadn't added F2802x_GlobalVariableDefs.c). The F2802x_I2C.c file contains just an initialization function for the GPIOs and another init function that says `//tbd...` which I guess stands for To Be Done.

2. So, does this mean it's not implemented in the library? Any particular reason?

I have a related question too. Some examples (e.g. gpio_toggle) use the ACRONYM_function style of functions (e.g. CLK_setOscSrc) while others (e.g. i2c_eeprom) use other kinds of functions not included in driverlib.lib (e.g. InitSysCtrl). Which set of functions is preferred? Is it that the i2c_eeprom example is outdated for example? Would I be able to use I2CA_ReadData and other functions from that example or they are outdated and shouldn't be relied on?

Shahbaz

Hi Igor,

Ok thanks. I needed this confirmation that the functions used in the I2C example are reliable and not outdated.

Shahbaz

Ok, Shahbaz!

I'm glad if my help was effective.

Good luck,

Igor
