Other Parts Discussed in Thread: CC2640R2F, CC2650

Hello,

Could you please let me know which example is good in order to undertand how to build the I2C interface in Lanchxl-CC2640R2? I use the existed driver but I face many problems. Any help for someone who has managed to write/read in I2C of CC2640R2? 

Thank youin advance

    The drivers should work the same for both the CC2650 and CC2640R2F. I would just look at how the I2C is implemented in the sensortag project in the v2.2.1 SDK release.

    Best wishes

    Thank you very much for your prompt response. It is not the same! Unfortunately, there are some differences. My code works very well but in the I2C, I cannot see any signal at SDA and SCL. If anyone has worked on it, any guideline would very helpful for me.

    Kind regards,

    Have you also looked at the TI drivers usage documentation in the latest SDK:
    file:///C:/ti/simplelink_cc2640r2_sdk_1_30_00_25/docs/tidrivers/doxygen/html/_i2_c_8h.html

    Thank you very much for your help!

    Indeed, I include the files in the application SimpleBLEPeripheral.c file. Is there any possibility the problem to be due to the fact that I didn't insert special folder "I2C" in the "Drivers" folder?

    Please give me a simple example for CCS with I2C? Also, only the "simplelink_cc2640r2_sdk_1_00_00_22" stack is available here: http://www.ti.com/tool/BLe-Stack

    Thank you in advance,

    Hi, 

    There is I2C example for CCS in Resource Explorer:

    For the i2ctmp007 project: SDK->Examples->Development Tools->CC2640R2 LaunchPad -> TI Drivers->i2ctmp007

    For SLA: SDK -> SimpleLink Academy -> Bluetooth LE -> Bluetooth Low Energy + Sensors BoosterPack

    Best wishes

    Dear Zahid,

    Should I change the library of SensorI2C acccording to CC2540r2? For example to change the Semaphore to Event, etc...?
    The Resource Explores leads me to SDK->Examples->Development Tools->CC2640R2 LaunchPad -> TI Drivers-
    Thank you,
