Segger build error with twi

[mahi354]

Hello, sir.

I'm using IDE segger embedded studio to programme the nrf52840 DK board (SDK17.0).

I'm experiencing a problem with the twi interface. When I enable it, I get the following errors. I'm confused as to how to fix this problem.

can you please let me know how to resolve the problem.

unknown type name 'nrf_drv_twi_evt_handler_t'

unknown type name 'nrf_drv_twi_config_t'

unknown type name 'nrfx_twim_evt_t'

unknown type name 'nrfx_twi_evt_t'

unknown type name 'nrf_drv_twi_t'; did you mean 'nrfx_drv_state_t'?

unknown type name 'nrf_drv_twi_config_t'

unknown type name 'nrf_drv_twi_evt_handler_t'

Hi, 

Please make sure that at least one of these are set in your sdk_config.h file:

#define TWI_ENABLED 1
#define NRFX_TWI_ENABLED 1
#define NRFX_TWIM_ENABLED 1

Check the TWI Scanner Example for default config. If this does not help, please upload your sdk_config.h file for review.

Also, you should include nrf_drv_twi.c, nrfx_twi.c and nrfx_twim.c.

Regards,
Amanda

Hi ,

• I checked the sdk config.h file and everything you mentioned is enabled; I'm using SDK 17.0.
  Please review the sdk file and let me know what I've done incorrectly.0842.sdk_config.h.txt
