## Function Documentation

## ◆ hal_adc_voltage_extern()

void hal_adc_voltage_extern | ( | adc_handle_t * | hadc,
|  | double | vref,
|  | uint16_t * | inbuf,
|  | double * | outbuf,
|  | uint32_t | buflen
| ) |  |

Convert the ADC conversion results to a voltage value(external reference).

Parameters

  [in] | hadc | Pointer to a ADC handle which contains the configuration information for the specified ADC module.
  [in] | vref | slope of ADC.
  [in] | inbuf | Pointer to data buffer which storage ADC conversion results.
  [out] | outbuf | Pointer to data buffer which to storage voltage results.
  [in] | buflen | Length of data buffer, ranging between 0 and 4095.

Returns
  Result of operation.
