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.

◆ biasProg

uint32_t ACMP_CapsenseInit_TypeDef::biasProg

Bias current.

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

◆ hysteresisLevel_0

ACMP_HysteresisLevel_TypeDef ACMP_CapsenseInit_TypeDef::hysteresisLevel_0

Hysteresis level when ACMP output is 0.

◆ hysteresisLevel_1

ACMP_HysteresisLevel_TypeDef ACMP_CapsenseInit_TypeDef::hysteresisLevel_1

Hysteresis level when ACMP output is 1.

◆ resistor

ACMP_CapsenseResistor_TypeDef ACMP_CapsenseInit_TypeDef::resistor

A resistor used in the capacative sensing circuit.

For values see the device data sheet.

◆ vddLevelHigh

uint32_t ACMP_CapsenseInit_TypeDef::vddLevelHigh

This value configures the upper voltage threshold of the capsense oscillation rail.

The voltage threshold is calculated as follows: VDD * (vddLevelHigh + 1) / 64

◆ vddLevelLow

uint32_t ACMP_CapsenseInit_TypeDef::vddLevelLow

This value configures the lower voltage threshold of the capsense oscillation rail.

The voltage threshold is calculated as follows: VDD * (vddLevelLow + 1) / 64

◆ enable

bool ACMP_CapsenseInit_TypeDef::enable

If true, ACMP is enabled after configuration.
