Field Documentation

◆ fullBias

bool ACMP_CapsenseInit_TypeDef::fullBias

Full-bias current.

See the ACMP chapter about bias and response time in the reference manual for details.

◆ halfBias

bool ACMP_CapsenseInit_TypeDef::halfBias

Half-bias current.

See the ACMP chapter about bias and response time in the reference manual for details.

◆ biasProg

uint32_t ACMP_CapsenseInit_TypeDef::biasProg

Bias current.

See the ACMP chapter about bias and response time in the reference manual for details.

◆ warmTime

ACMP_WarmTime_TypeDef ACMP_CapsenseInit_TypeDef::warmTime

Warmup time, which is measured in HFPERCLK / HFPERCCLK cycles and should be about 10 us in wall clock time.

◆ hysteresisLevel

ACMP_HysteresisLevel_TypeDef ACMP_CapsenseInit_TypeDef::hysteresisLevel

Hysteresis level.

◆ resistor

ACMP_CapsenseResistor_TypeDef ACMP_CapsenseInit_TypeDef::resistor

A resistor used in the capacative sensing circuit.

For values see the device data sheet.

◆ lowPowerReferenceEnabled

bool ACMP_CapsenseInit_TypeDef::lowPowerReferenceEnabled

Low-power reference enabled.

This setting, if enabled, reduces the power used by VDD and bandgap references.

◆ vddLevel

uint32_t ACMP_CapsenseInit_TypeDef::vddLevel

VDD reference value.

VDD_SCALED = (VDD * VDDLEVEL) / 63. Valid values are in the 0-63 range.

◆ enable

bool ACMP_CapsenseInit_TypeDef::enable

If true, ACMP is enabled after configuration.
