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

Hi Mahesh,

Since Amanda is on leave, I have taken over this case and will try to help you resolve the issue. Have you added the .c files to the source files? Please do check this and let me know how it goes.
