Hi,
In SDK 15.3 I have found a bug in internal implementation of the lps22hb external driver.
Bug description:
Unable to set properly a INT_S[2:1] bits in CTRL_REG3 register which is a INT_DRDY pin configuration.
File: lps22hb_internal.h
Source code fragment in topic:
#define LPS22HB_INTERNAL_DRDY_CFG(_s, _activ, _pp_od, _fss, _fth, _ovr, _drdy, _high, _low) \
NRF_TWI_SENSOR_REG_SET(_s.ctrl_reg[2], LPS22HB_INT_H_L_MASK, LPS22HB_INT_H_L_POS, _activ); \
NRF_TWI_SENSOR_REG_SET(_s.ctrl_reg[2], LPS22HB_PP_OD_MASK, LPS22HB_PP_OD_POS, _pp_od); \
NRF_TWI_SENSOR_REG_SET(_s.ctrl_reg[2], LPS22HB_F_FSS5_MASK, LPS22HB_F_FSS5_POS, _fss); \
NRF_TWI_SENSOR_REG_SET(_s.ctrl_reg[2], LPS22HB_F_FTH_MASK, LPS22HB_F_FTH_POS, _fth); \
NRF_TWI_SENSOR_REG_SET(_s.ctrl_reg[2], LPS22HB_F_OVR_MASK, LPS22HB_F_OVR_POS, _ovr); \
NRF_TWI_SENSOR_REG_SET(_s.ctrl_reg[2], \
LPS22HB_INT_S_MASK, \
LPS22HB_INT_S_MASK, \
(_low << 1) + _high);
The problem exist in the last register set:
NRF_TWI_SENSOR_REG_SET(_s.ctrl_reg[2], \
LPS22HB_INT_S_MASK, \
LPS22HB_INT_S_MASK, \
(_low << 1) + _high);
In use of 'NRF_TWI_SENSOR_REG_SET()' at third parameter - which should be a bit position, need to pass a 'LPS22HB_INT_S_POS' instead of 'LPS22HB_INT_S_MASK'
