Hi,
I'm using SDK 15.0.0; nrf52840 DK; IAR(EWARM).
I want to add TWI(i2c) from example in SDK to my project.
But I facing with next errors:
Error[Li005]: no definition for "nrfx_twim_enable" [referenced from D:\Projects\NRF52\MyProject\application\iar\_build\i2c_module.o]
Error[Li005]: no definition for "nrfx_twim_init" [referenced from D:\Projects\NRF52\MyProject\application\iar\_build\nrf_drv_twi.o]
Error while running Linker
1) I have added all headers from TWI example to my .c file:
#include "nrf_gpio.h" #include "boards.h" #include "app_util_platform.h" #include "app_error.h" #include "nrf_drv_twi.h" #include "nrf_delay.h" #include "nrf_log.h" #include "nrf_log_ctrl.h" #include "nrf_log_default_backends.h"
2) I have set additional pathes in C/C++ Preprocessor (here is not full list, just all that was new in TWI example)
$PROJ_DIR$\..\..\..\..\..\..\integration\nrfx
$PROJ_DIR$\..\..\..\..\..\..\integration\nrfx\legacy
$PROJ_DIR$\..\..\..\..\..\..\modules\nrfx
$PROJ_DIR$\..\..\..\..\..\..\modules\nrfx\drivers\include
$PROJ_DIR$\..\..\..\..\..\..\modules\nrfx\hal
$PROJ_DIR$\..\..\..\..\..\..\modules\nrfx\mdk
$PROJ_DIR$\..\..\..\..\..\..\components\drivers_nrf\nrf_soc_nosd
3) In sdk_config.h I have changed:
#ifndef NRFX_TWIM_ENABLED #define NRFX_TWIM_ENABLED 1//0 #endif #ifndef TWI_ENABLED #define TWI_ENABLED 1//0 #endif #ifndef TWI0_ENABLED #define TWI0_ENABLED 1//0 #endif #ifndef TWI0_USE_EASY_DMA #define TWI0_USE_EASY_DMA 1//0 #endif
4) I have added nrf_drv_twi.c file in project's folder nRF_Drivers (I can open this file without issues):
Please advice what else should I do?
Regards!
