Hi all,
i am trying to merge ble_app_peripheral example with twi_scanner. So i created twi_ad7147.h and twi_ad7147.c with the twi configurations.
But i am getting this error when linking
linking... .\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrf_drv_twi_init (referred from twi_ad7147.o). .\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrfx_twim_enable (referred from twi_ad7147.o). .\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrfx_twim_rx (referred from twi_ad7147.o). .\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nrfx_twim_tx (referred from twi_ad7147.o).

".\_build\nrf52832_xxaa.axf" - 4 Error(s), 5 Warning(s). Target not created. Build Time Elapsed: 00:00:03
I am including these files in the main, a
#include "nrf_twi.h" #include "nrf_twim.h" #include "nrf_drv_twi.h"
Also my sdk_config.h is like:
// <e> NRFX_TWI_ENABLED - nrfx_twi - TWI peripheral driver //========================================================== #ifndef NRFX_TWI_ENABLED #define NRFX_TWI_ENABLED 1 #endif // <q> NRFX_TWI0_ENABLED - Enable TWI0 instance #ifndef NRFX_TWI0_ENABLED #define NRFX_TWI0_ENABLED 1 #endif // <q> NRFX_TWI1_ENABLED - Enable TWI1 instance #ifndef NRFX_TWI1_ENABLED #define NRFX_TWI1_ENABLED 0 #endif #ifndef NRFX_TWI_DEFAULT_CONFIG_IRQ_PRIORITY #define NRFX_TWI_DEFAULT_CONFIG_IRQ_PRIORITY 6 #endif // <e> NRFX_TWI_CONFIG_LOG_ENABLED - Enables logging in the module. //========================================================== #ifndef NRFX_TWI_CONFIG_LOG_ENABLED #define NRFX_TWI_CONFIG_LOG_ENABLED 0 #endif // <o> NRFX_TWI_CONFIG_LOG_LEVEL - Default Severity level // <0=> Off // <1=> Error // <2=> Warning // <3=> Info // <4=> Debug #ifndef NRFX_TWI_CONFIG_LOG_LEVEL #define NRFX_TWI_CONFIG_LOG_LEVEL 3 #endif // <e> NRFX_UARTE_ENABLED - nrfx_uarte - UARTE peripheral driver //========================================================== #ifndef NRFX_UARTE_ENABLED #define NRFX_UARTE_ENABLED 1 #endif // <o> NRFX_UARTE0_ENABLED - Enable UARTE0 instance #ifndef NRFX_UARTE0_ENABLED #define NRFX_UARTE0_ENABLED 0 #endif // <q> NRF_TWI_SENSOR_ENABLED - nrf_twi_sensor - nRF TWI Sensor module #ifndef NRF_TWI_SENSOR_ENABLED #define NRF_TWI_SENSOR_ENABLED 0 #endif // <q> NRF_TWI_MNGR_ENABLED - nrf_twi_mngr - TWI transaction manager #ifndef NRF_TWI_MNGR_ENABLED #define NRF_TWI_MNGR_ENABLED 0 #endif // <e> NRFX_TWIM_ENABLED - nrfx_twim - TWIM peripheral driver //========================================================== #ifndef NRFX_TWIM_ENABLED #define NRFX_TWIM_ENABLED 1 #endif // <q> NRFX_TWIM0_ENABLED - Enable TWIM0 instance #ifndef NRFX_TWIM0_ENABLED #define NRFX_TWIM0_ENABLED 1 #endif // <q> NRFX_TWIM1_ENABLED - Enable TWIM1 instance #ifndef NRFX_TWIM1_ENABLED #define NRFX_TWIM1_ENABLED 0 #endif // <o> NRFX_TWIM_DEFAULT_CONFIG_FREQUENCY - Frequency // <26738688=> 100k // <67108864=> 250k // <104857600=> 400k #ifndef NRFX_TWIM_DEFAULT_CONFIG_FREQUENCY #define NRFX_TWIM_DEFAULT_CONFIG_FREQUENCY 26738688 #endif // <q> NRFX_TWIM_DEFAULT_CONFIG_HOLD_BUS_UNINIT - Enables bus holding after uninit #ifndef NRFX_TWIM_DEFAULT_CONFIG_HOLD_BUS_UNINIT #define NRFX_TWIM_DEFAULT_CONFIG_HOLD_BUS_UNINIT 0 #endif
Any help please?
