Linker error: undefined reference to 'nrfx_twim_xfer'

robert0606

Hello, how can I use the functions in nrfx_twim.c

Using SES and the CMSIS config wizard, I have picked:

NRFX_TWIM_ENABLED 1

NRFX_TWIM0_ENABLED 1

NRFX_TWIS_ENABLED 0

NRFX_TWI_ENABLED 0

TWIS_ENABLED 0

TWI_ENABLED 0

In the IDE, the source for nrfx_twim.c is all 'greyed out'.

    Hi,

    You need to also add the files as part of the project and add the path where the files is located to the user included directories in the project settings. See this for more.

    Your sdk_config file should be similar to the TWIM example from the SDK. I suggest comparing the two:

    I found the combination. You have to pick

    TWI_ENABLED 1

    TWI0_ENABLED 1

    TWI0_USE_EASY_DMA 1

    NRFX_TWIM_ENABLED 1

    NRFX_TWIM0_ENABLED 1
