i am using the SDK 15.0.0 ， using the i2c_sensor_driver.c,NRF_DRV_TWI_INSTANCE error problem has been resolved.but i found a question, as follows:

//twi:

m_xfer_done = false;
err_code = nrf_drv_twi_tx(&m_twi, SENSOR_ADDR, reg, sizeof(reg), false);
APP_ERROR_CHECK(err_code);
while (m_xfer_done == false);

//spi:

KX123_spi_activate_cs();/*no delay*/
spi_xfer_done = false;
APP_ERROR_CHECK(nrf_drv_spi_transfer(&kx123_spi_instance, tx_data, 2, NULL, 0));
while(!spi_xfer_done);
KX123_spi_deactivate_cs();

i also need to wait for complete flag every time? this way will cause system halted.

Hi,

It is hard to tell without more information.

What SDK version is this, and what SoC? (SDK 14.2? nRf52832?)

Is your application based on an example, if so which example?

Can you share the full build log?

Can you share i2c_sensor_driver.c?

Regards,
Terje
