Hi all.
Consumption current increases by about 1.5 mA after a battery check.
uint8_t battery_start(void) { // Configure ADC NRF_ADC->INTENSET = ADC_INTENSET_END_Msk; NRF_ADC->CONFIG = (ADC_CONFIG_RES_8bit << ADC_CONFIG_RES_Pos) | (ADC_CONFIG_INPSEL_SupplyOneThirdPrescaling << ADC_CONFIG_INPSEL_Pos) | (ADC_CONFIG_REFSEL_VBG << ADC_CONFIG_REFSEL_Pos) | (ADC_CONFIG_PSEL_Disabled << ADC_CONFIG_PSEL_Pos) | (ADC_CONFIG_EXTREFSEL_None << ADC_CONFIG_EXTREFSEL_Pos); NRF_ADC->EVENTS_END = 0; NRF_ADC->ENABLE = ADC_ENABLE_ENABLE_Enabled;
NRF_ADC->EVENTS_END = 0; // Stop any running conversions.
NRF_ADC->TASKS_START = 1;
while (NRF_ADC->EVENTS_END == 0)
{
}
{
uint8_t adc_result;
uint16_t batt_lvl_in_milli_volts;
uint32_t err_code;
NRF_ADC->EVENTS_END = 0;
adc_result = NRF_ADC->RESULT;
NRF_ADC->TASKS_STOP = 1;
batt_lvl_in_milli_volts = ADC_RESULT_IN_MILLI_VOLTS(adc_result) +
DIODE_FWD_VOLT_DROP_MILLIVOLTS;
NRF_ADC->INTENSET = 0;
NRF_ADC->INTENCLR = 0x1;
NRF_ADC->CONFIG = 0;
NRF_ADC->EVENTS_END = 0;
NRF_ADC->TASKS_START = 0;
NRF_ADC->ENABLE = 0;
*this point return battery_level_in_percent(batt_lvl_in_milli_volts); } }
