Sampling rate L011 too slow

Sounds like something is misconfigured or the clocking is not ​as imagined.

Provide minimal code that demonstrates the failure case.​

//This is Trigger to Start measuring void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin) {

if(HAL_GetTick() > lastTrig + 500){

HAL_ADC_Start_DMA(&hadc, (uint32_t*) &adc_buffer, bufferSize);

lastTrig = HAL_GetTick();

}

}

//And there is handler to manipulate with measured values:

void DMA_IRQHandler() {

for (int i = 0; i < bufferSize; i += 3) {

voltage = adc_buffer[i];

current = adc_buffer[i + 1];

refVoltage = adc_buffer[i + 2];

refVoltage = __LL_ADC_CALC_VREFANALOG_VOLTAGE(refVoltage,

LL_ADC_RESOLUTION_12B);

voltage = __LL_ADC_CALC_DATA_TO_VOLTAGE(refVoltage, voltage,

LL_ADC_RESOLUTION_12B);

current = __LL_ADC_CALC_DATA_TO_VOLTAGE(refVoltage, current,

LL_ADC_RESOLUTION_12B);

//some more stuff to manipulate with measured data

}
