powrms_eeprom_read_def_v_temp_comp_val()

int powrms_eeprom_read_def_v_temp_comp_val

(

int32_t *

value

)

Read default voltage temperature compensation value from EEPROM.

This function reads the default voltage temperature compensation value using single-byte reads to avoid I2C bus blocking issues that can occur with large transfers. The int32_t value is read byte by byte and reconstructed in little-endian format.

int powrms_eeprom_read_v_temp_comp_val

(

int32_t *

value

)

Read voltage temperature compensation value from EEPROM.

This function reads the voltage temperature compensation value using single-byte reads to avoid I2C bus blocking issues that can occur with large transfers. The int32_t value is read byte by byte and reconstructed in little-endian format.

int powrms_eeprom_write_def_v_temp_comp_val

(

int32_t

value

)

Write default voltage temperature compensation value to EEPROM.

This function writes the default voltage temperature compensation value using single-byte writes to avoid I2C bus blocking issues that can occur with large transfers. The int32_t value is broken down into bytes and written individually in little-endian format.
