Changelog

All notable changes to this project are documented in this file.

[1.2.1] - 2025-09-11

Fixed

  • Fixed issue in npmx_adc_meas_get where 2 lsbits would be incorrect.

[1.2.0] - 2025-08-12

Changed

  • npmx_charger_charging_current_get and npmx_charger_charging_current_set now uses microamperes instead of milliamperes in order to support the more fine-grained adjustment options for nPM1304.

  • Allowed values for npmx_charger_discharging_current_set is updated to be aligned with nPM1300 Product Specification v1.2. There are now only two allowed values: 200 mA and 1000 mA (low and high limits).

  • npmx_charger_discharging_current_set no longer returns NPMX_ERROR_NOT_SUPPORTED when used with nPM1304 (which only has a single allowed battery discharge limit value).

  • nPM1300 battery current calculation updated to be aligned with nPM1300 Product Specification v1.2.

  • Updated LDSW soft start current options to be aligned with nPM1300 Product Specification v1.x.

  • Added porting guide.

[1.1.0] - 2025-05-28

Fixed

  • Fixed offset issue in npmx_adc_meas_all_get.

  • Fixed -Wdouble-promotion build warnings.

Added

  • Added support for nPM1304 PMIC.

Changed

  • npmx_adc ibat measurement is now reported in microamperes instead of milliamperes.

  • NPMX_ADC_IBAT_MEAS_CURRENT_RFU member removed from npmx_adc_ibat_meas_current_t enum.

[1.0.1] - 2024-07-12

Fixed

  • Corrected discharge fullscale current.

  • Corrected charge fullscale current.

  • Update current limit on set.

[1.0.0] - 2023-12-01

Added

  • Added ADK v1.4.0.

  • Added the npmx_adc_ntc_config_t structure to the ADC driver. The structure contains a thermistor type and NTC beta value.

  • Added npmx_charger_*_temperature_* functions for getting and setting NTC temperature threshold using temperature in degrees Celsius.

  • Added the restore_values initialization parameter to the npmx_core_init function. Now, the following values can be restored from a PMIC device during its initialization: ADC burst mode enable, NTC beta value, charging current, discharging current, and ship button inversion status.

  • Added mathematical functions used in npmx to npmx_common.

Changed

  • Changed the temperature type in the npmx_charger_die_temp_* functions. Now they accept negative values.

  • Changed a function for setting and reading the NTC type in the ADC driver. Now the npmx_adc_ntc_config_t configuration structure is passed as an argument to npmx_adc_ntc_config_* functions.

  • Changed the NTC resistance calculation to the battery temperature calculation in the ADC driver. The NPMX_ADC_MEAS_NTC enumeration which used to return measurement in Ohms has been replaced by NPMX_ADC_MEAS_BAT_TEMP which returns temperature in millidegrees Celsius.

  • Changed a behavior of the npmx_timer_config_set function. Now it triggers the NPMX_TIMER_TASK_STROBE task after setting the configuration.

  • Changed a compilation define that should be used when building for nPM1300 from NPM1300_ENG_C to NPM1300.

  • Changed the template file name for nPM1300 from templates/npmx_config_npm1300_eng_c.h to templates/npmx_config_npm1300.h.

  • Changed the behavior of the npmx_callback_to_str and npmx_callback_bit_to_str functions. Now, strings will be returned instead of a NULL pointer when building with NPMX_DEBUG defined.

  • Changed values in the npmx_ldsw_soft_start_current_t.

Fixed

  • Fixed an issue in the npmx_ldsw_soft_start_config_get function that caused an incorrect enable state.

  • Fixed an issue in the npmx_charger_die_temp_* functions that caused incorrect temperature calculations in the charger driver.

  • Fixed an issue with the NPMX_ADC_MEAS_BAT_TEMP parameter in the npmx_adc_meas_get function. The issue caused an inaccurate die temperature calculation in the charger driver.

  • Fixed an issue in the npmx_adc_meas_get and npmx_adc_meas_all_get functions that caused an incorrect value to be returned.

  • Fixed an issue in the npmx_callback_bit_to_str function that caused an incorrect string description to be returned.

  • Fixed an issue in the npmx_ship_reset_config_set function that caused an incorrect task to be called.

  • Fixed minor issues in documentation.
