.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrfx_twis_enable (referred from main.o).

Hi,

I try to implement the nrf52832 as the TWI slave but get the following error messages:

I have added the nrf.twis.c to the project, included in the main application and did the configuration like this.

Do I still miss anything?

Thanks in advance.

Hi,

Do you have the symbol TWIS_ENABLED defined in your sdk_config.h file? If this is defined as 0, you will see this error, as the nrfx configs are overwritten by the legacy layer. Please remove/comment out this define if you have it in your file.

Best regards,
Jørgen

Great. Problem solved. Thank you very much, Jorgen.

Would you mind talking a little bit about the legacy layer? I don't find much information about it.

Thanks,

Duncan
