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.
