LIS2DH12 driver issue in nRF SDK v15.0

[aaronxu]

Hi,

There are several new drivers under "nRF5_SDK_15.0.0_a53641a\components\drivers_ext\", but no example now.

I have setup the HTS221 driver and it works. I turn to LIS2DH12 driver, but it not work.

For send and receive more i2c data then HTS221, I change some Marco like this:

#define MAX_PENDING_TRANSACTIONS    33

#define LIS2DH12_MIN_QUEUE_SIZE       32

And read who_am_i successfully.

when try to read accelerate data, it stuck in somewhere, where I cannot traced.

Could you kindly share with me a example, which is using the new LIS2DH12 driver?

Define and configuration:

#define TWI_INSTANCE_ID             0

#define MAX_PENDING_TRANSACTIONS    33

#define LIS2DH12_MIN_QUEUE_SIZE       32

NRF_TWI_MNGR_DEF(m_nrf_twi_mngr, MAX_PENDING_TRANSACTIONS, TWI_INSTANCE_ID);

NRF_TWI_SENSOR_DEF(m_nrf_twi_sensor, &m_nrf_twi_mngr, LIS2DH12_MIN_QUEUE_SIZE);

LIS2DH12_INSTANCE_DEF(m_lis2dh12, &m_nrf_twi_sensor, LIS2DH12_BASE_ADDRESS_LOW);


...

    LIS2DH12_DATA_CFG(m_lis2dh12, LIS2DH12_ODR_100HZ, false, 1, 1, 1, LIS2DH12_SCALE_2G, 1);
    LIS2DH12_FIFO_CFG(m_lis2dh12, false, LIS2DH12_BYPASS, false, 0x00);

    err_code = lis2dh12_init(&m_lis2dh12);
    APP_ERROR_CHECK(err_code);

...

after that,

lis2dh12_data_read(&m_lis2dh12, lis2dh12_data_read_cb, &accel_data, sizeof(accel_data));
