enaScanCh#

bool LESENSE_ChDesc_TypeDef::enaScanCh

Set to enable scan channel CHx.

enaPin#

bool LESENSE_ChDesc_TypeDef::enaPin

Set to enable CHx pin.

enaInt#

bool LESENSE_ChDesc_TypeDef::enaInt

Enable/disable channel interrupts after configuring all the sensor channel parameters.

chPinExMode#

LESENSE_ChPinExMode_TypeDef LESENSE_ChDesc_TypeDef::chPinExMode

Configure channel pin mode for the excitation phase of the scan sequence.

Note: OPAOUT is only available on channels 2, 3, 4, and 5.

chPinIdleMode#

LESENSE_ChPinIdleMode_TypeDef LESENSE_ChDesc_TypeDef::chPinIdleMode

Configure channel pin idle setup in LESENSE idle phase.

useAltEx#

bool LESENSE_ChDesc_TypeDef::useAltEx

Set to use alternate excite pin for excitation.

shiftRes#

bool LESENSE_ChDesc_TypeDef::shiftRes

Set to enable result from this channel being shifted into the decoder register.

invRes#

bool LESENSE_ChDesc_TypeDef::invRes

Set to invert result bit stored in the SCANRES register.

storeCntRes#

LESENSE_StoreSample_TypeDef LESENSE_ChDesc_TypeDef::storeCntRes

Set to store counter value in the RAM (accessible via RESDATA) and make the comparison result available in the SCANRES register.

exClk#

LESENSE_ChClk_TypeDef LESENSE_ChDesc_TypeDef::exClk

Select clock used for the excitation timing.

sampleClk#

LESENSE_ChClk_TypeDef LESENSE_ChDesc_TypeDef::sampleClk

Select clock used for the sample delay timing.

exTime#

uint8_t LESENSE_ChDesc_TypeDef::exTime

Configure the excitation time.

Excitation will last exTime+1 excitation clock cycles. Valid range: 0-63 (6 bits).

sampleDelay#

uint8_t LESENSE_ChDesc_TypeDef::sampleDelay

Configure the sample delay.

Sampling will occur after sampleDelay+1 sample clock cycles. Valid range: 0-127 (7 bits) or 0-255 (8 bits) depending on device.

measDelay#

uint16_t LESENSE_ChDesc_TypeDef::measDelay

Configure the measure delay.

Sensor measuring is delayed for measDelay excitation clock cycles. Valid range: 0-127 (7 bits) or 0-1023 (10 bits) depending on device.

acmpThres#

uint16_t LESENSE_ChDesc_TypeDef::acmpThres

Configure the ACMP threshold or the DAC data.

If perCtrl.dacCh0Data or perCtrl.dacCh1Data is set to lesenseDACIfData, acmpThres defines the 12-bit DAC data in the corresponding data register of DAC interface (DACn_CH0DATA and DACn_CH1DATA). In this case, the valid range is: 0-4095 (12 bits). If perCtrl.dacCh0Data or perCtrl.dacCh1Data is set to lesenseACMPThres, acmpThres defines the 6-bit Vdd scaling factor of ACMP negative input (VDDLEVEL in ACMP_INPUTSEL register). In this case, the valid range is: 0-63 (6 bits).

sampleMode#

LESENSE_ChSampleMode_TypeDef LESENSE_ChDesc_TypeDef::sampleMode

Select if the ACMP output, the ADC output or the counter output should be used in comparison.

intMode#

LESENSE_ChIntMode_TypeDef LESENSE_ChDesc_TypeDef::intMode

Configure the interrupt generation mode for the CHx interrupt flag.

cntThres#

uint16_t LESENSE_ChDesc_TypeDef::cntThres

Configure the decision threshold for the sensor data comparison.

Valid range: 0-65535 (16 bits).

compMode#

LESENSE_ChCompMode_TypeDef LESENSE_ChDesc_TypeDef::compMode

Select the mode for counter comparison.

evalMode#

LESENSE_ChEvalMode_TypeDef LESENSE_ChDesc_TypeDef::evalMode

Select the sensor evaluation mode.

offset#

uint8_t LESENSE_ChDesc_TypeDef::offset

Offset for IADC/ACMP interaction.

ACMP: offset determines which of the port I/O pins on the external override interface to access. IADC: offset determines which of the IADC scanner channels is sampled.
