Functions

void ACMP_CapsenseChannelSet ( ACMP_TypeDef *acmp, ACMP_Channel_TypeDef channel)
Sets the ACMP channel used for capacative sensing.
void ACMP_CapsenseInit ( ACMP_TypeDef *acmp, const ACMP_CapsenseInit_TypeDef *init)
Sets up the ACMP for use in capacative sense applications.
void ACMP_ChannelSet ( ACMP_TypeDef *acmp, ACMP_Channel_TypeDef negSel, ACMP_Channel_TypeDef posSel)
Sets which channels should be used in ACMP comparisons.
void ACMP_Disable ( ACMP_TypeDef *acmp)
Disables the ACMP.
void ACMP_Enable ( ACMP_TypeDef *acmp)
Enables the ACMP.
void ACMP_GPIOSetup ( ACMP_TypeDef *acmp, uint32_t location, bool enable, bool invert)
Sets up GPIO output from the ACMP.
void ACMP_Init ( ACMP_TypeDef *acmp, const ACMP_Init_TypeDef *init)
Initialize ACMP.
__STATIC_INLINE void ACMP_IntClear ( ACMP_TypeDef *acmp, uint32_t flags)

__STATIC_INLINE void ACMP_IntSet ( ACMP_TypeDef *acmp, uint32_t flags)
Set one or more pending ACMP interrupts from SW.
void ACMP_Reset ( ACMP_TypeDef *acmp)
Reset ACMP to same state as after a HW reset.
