setup HTS221 with nrf52832

[dewal]

I am trying to integrate code on hts221 with an nrf52832. I am using sdk15a for referring the .h and .c of hts221.

NRF_TWI_MNGR_DEF(m_nrf_twi_mngr, MAX_PENDING_TRANSACTIONS, TWI_INSTANCE_ID);
NRF_TWI_SENSOR_DEF(m_twi_sensor, &m_nrf_twi_mngr, 128);
HTS221_INSTANCE_DEF(m_hts221, &m_twi_sensor, HTS221_ADDR ); 

how to call this macros( in hts221.c) into the main file

I am not sure this is correct ?

HTS221_WRITE(m_hts221, msg);

also problem in how to call this function into main file

ret_code_t hts221_temp_read(hts221_instance_t *       p_instance,
                            hts221_data_callback_t    user_callback,
                            int16_t *                 p_temp)
{
    ASSERT(p_instance != NULL);
    return nrf_twi_sensor_reg_read(p_instance->p_sensor_data,
                                   p_instance->sensor_addr,
                                   HTS221_REG_TEMP_OUT_L | HTS221_INCR_REG_MASK,
                                   (nrf_twi_sensor_reg_cb_t) user_callback,
                                   (uint8_t *) p_temp,
                                   2);
}

i am trying but getting errror.

 If anyone knows please help me.(anyone having code hts221 twi interfacing please provide)

Hi,

Which error are you getting? There is no example of using this driver in the SDK, but maybe the code in this post may provide you with a starting-point.

There is also a driver for this sensor in the Thingy:52 FW.

Best regards,
Jørgen

which parameter need t pass to this function(nrf_twi_sensor)?

ret_code_t hts221_temp_read(hts221_instance_t *       p_instance,
                            hts221_data_callback_t    user_callback,
                            int16_t *                 p_temp)
{
    ASSERT(p_instance != NULL);
    return nrf_twi_sensor_reg_read(p_instance->p_sensor_data,
                                   p_instance->sensor_addr,
                                   HTS221_REG_TEMP_OUT_L | HTS221_INCR_REG_MASK,
                                   (nrf_twi_sensor_reg_cb_t) user_callback,
                                   (uint8_t *) p_temp,
                                   2);
}

above error occured while calling this function in main file.
