Error[Pe020]: identifier "NRF_DRV_TWI_INSTANCE_0" is undefined

[M_VLV]

Hi,

I'm using SDK 15.0.0.

I'm trying to run part of TWI example in my project in separate .c file. 

But I have next error:

Error[Pe020]: identifier "NRF_DRV_TWI_INSTANCE_0" is undefined D:\Projects\NRF52\MyProject\application\source\i2c_module.c 82

Proper header nrf_drv_twi.h is included (I included all headers from twi_sensor example).

Please advice what am I missing?

Did you enable TWI0 in sdk_config.h?

// <e> TWI0_ENABLED - Enable TWI0 instance
//==========================================================
#ifndef TWI0_ENABLED
#define TWI0_ENABLED 1
#endif

this solved problem, thanks!

Hi again, Jørgen

My config seems all fine

#define NRFX_TWIM_ENABLED 1
#define NRFX_TWI_ENABLED 1
#define TWI_ENABLED 1
#define TWI0_ENABLED 1
#define TWI0_USE_EASY_DMA 1

But I'm still getting this error. :(

What am I doing wrong here?

Are you getting this exact error?

[usmanmehmood55]

I think so. 

I'm getting 

'NRF_DRV_TWI_INSTANCE_0' undeclared here (not in a function); did you mean 'NRF_DRV_TWI_INSTANCE_'?

I've also posted the problem here, but there is no response on it. And I'm so close to making my application work, but this error is keeping me from completing it.
