CCS/CC2640R2F: BMI160 Driver project problem with SysConfig

Hi,

Thanks for your reply. Isn't there any actualised Example of how to integrate the BMI160 into the CC2640R2?

I have numerous projects in my CCS and I don't want to reinstall all, only to run this downgraded example.

Extra: Im trying to set the pins correctly with the Board file(the equivalent from "ti_drivers_config.h" f) but im getting Linking problems of the type...

...Is there a recommended strategy to approach this king of problems?

Hi Thomas,

You can copy/paste the parts of the application code from the example required to interface with the BMI160 through I2C.  I wouldn't expect you would have to reinstall all other projects when downloading/installing separate CCS/SDK/XDCTools versions.  You won't be able to modify ti_drivers_config.h if using a SysConfig project.  Here is a SimpleLink Academy Lab you can reference or perhaps the Custom Hardware section of the BLE User's Guide would help.

Hi Ryan,

Thanks again for your attention.

I was integrating the BMI160 application code into the simple_peripheral by copy/paste. I modified the PINs(SCL, SDA (and the interrupt CONFIG_GPIO_BMI160_INT1 --> DIO22 ??)) in the Board.h file and then got stuck in a display Linking error:

<Linking>

I will give it a try to the installation of the older versions that you suggested. However it would be really helpful if you could explain the origin of this error :)

Thanks in advance.

Thomas

What specific symbol and in which file?  This typically occurs if there is a missing library/command file not included in the Project Properties -> Build -> ARM Linker -> File Search Path.  You can do a diff compare of the BMI160 and Simple Peripheral examples to see if there are any differences.

Hi Ryan,

I followed your instructions from your first post. I installed the recommended versions with exception of the XDCTools v3.60.00.24 because I didn't found it , but the XDCTools 3.61.00.16 yes, which I installed.

Unfortunately it didn't work. It keep asking me for the "ti_drivers_config.h" file :

>> Compilation failure

subdir_rules.mk:7: recipe for target 'main_tirtos.obj' failed

"../main_tirtos.c", line 46: fatal error #1965: cannot open source file "ti_drivers_config.h"

1 catastrophic error detected in the compilation of "../main_tirtos.c".

Compilation terminated.

gmake: *** [main_tirtos.obj] Error 1

gmake: Target 'all' not remade because of errors.

**** Build Finished ****

So I checked the .syscfg file and it generates the files Board.h and Board.c . So I changed the imports to Board.h instead of ti_drivers_config.h(which by the way seems that it is only generated for other board versions, but not CC2640R2) and the following error came:

<Linking>

I navigated to the give path and I found out that the /lib/pdm_cc26x0r2.aem3 part is missing, i.e. no lib folder and consequently neither pdm_cc26x0r2.aem3 file. I don't know why it is missing and how to solve it.

Then I went back to the step where I was on the previous reply, that is integrating the BMI160 example to simple peripheral and did a diff compare of the File Search Paths and as it happens all of the paths from the BMI example were missing. I added them except for one of them... the one that gave me the previous error: ...lib/pdm_cc26x0r2.aem3

This was not present either in the SDK 4.20 used in the CCS 10.0

After all the "display" error remained:
