ACMP - Analog Comparator

Description

Analog comparator (ACMP) Peripheral API.

The Analog Comparator is used to compare voltage of two analog inputs with a digital output indicating which input voltage is higher. Inputs can either be one of the selectable internal references or from external pins. Response time and current consumption can be configured by altering the current supply to the comparator.

ACMP is available down to EM3 and is able to wake up the system when input signals pass a certain threshold. Use ACMP_IntEnable() to enable an edge interrupt to use this functionality.

This example shows how to use the em_acmp.h API for comparing an input pin to an internal 2.5 V reference voltage.

/* The ACMP is a high-frequency peripheral so we need to enable
* both the HFPER clock and the ACMP0 clock. */
/* Initialize with default settings. */
init. enable = false ;
ACMP_Init (ACMP0, &init);
/* In this example we want to compare an analog input to the 2.5 V
* internal reference. To achieve this we first have to configure the
* VB source which is used for internal reference voltages. */
ACMP_VBSetup (ACMP0, &vbconfig);
/* Now we select the two inputs to compare. Here we compare the APORT0XCH0
* input to the internal 2.5V reference that we previously configured. When
* APORT0XCH0 is lower than 2.5 V then the ACMP output is 0 and when
* APORT0XCH0 is is higher than 2.5 V then the ACMP output is 1. */
/* To be able to probe the output we can send the ACMP output to a pin.
* The second argument to this function is the pin location which is
* device dependent. */
ACMP_GPIOSetup (ACMP0, 0, true , false );
/* Finally we enable the ACMP. */
ACMP_Enable (ACMP0);
Note
ACMP can also be used to compare two separate input pins.

ACMP also contains specialized hardware for capacitive sensing. This module contains the ACMP_CapsenseInit() function to initialize ACMP for capacitive sensing and the ACMP_CapsenseChannelSet() function to select the current capsense channel.

For applications that require capacitive sensing it is recommended to use a library, such as cslib, which is provided by Silicon Labs.

Function Documentation

ACMP_CapsenseInit()

void ACMP_CapsenseInit ( ACMP_TypeDef * acmp,
const ACMP_CapsenseInit_TypeDef * init
)

Set up ACMP for use in capacitive sense applications.

This function sets up ACMP for use in capacitive sense applications. To use the capacitive sense functionality in the ACMP, use the PRS output of the ACMP module to count the number of oscillations in the capacitive sense circuit (possibly using a TIMER).

Note
A basic example of capacitive sensing can be found in the STK BSP (capsense demo).
Parameters
[in] acmp A pointer to the ACMP peripheral register block.
[in] init A pointer to the initialization structure used to configure ACMP for capacitive sensing operation.

ACMP_CapsenseChannelSet()

void ACMP_CapsenseChannelSet ( ACMP_TypeDef * acmp,
ACMP_Channel_TypeDef channel
)

Set the ACMP channel used for capacitive sensing.

Note
A basic example of capacitive sensing can be found in the STK BSP (capsense demo).
Parameters
[in] acmp A pointer to the ACMP peripheral register block.
[in] channel The ACMP channel to use for capacitive sensing (Possel).

ACMP_ChannelSet()

void ACMP_ChannelSet ( ACMP_TypeDef * acmp,
ACMP_Channel_TypeDef negSel,
ACMP_Channel_TypeDef posSel
)

Set which channels should be used in ACMP comparisons.

Parameters
[in] acmp A pointer to the ACMP peripheral register block.
negSel A channel to use on the negative input to the ACMP.
posSel A channel to use on the positive input to the ACMP.

ACMP_Disable()

void ACMP_Disable ( ACMP_TypeDef * acmp )

Disable ACMP.

Parameters
[in] acmp A pointer to the ACMP peripheral register block.

ACMP_Enable()

void ACMP_Enable ( ACMP_TypeDef * acmp )

Enable ACMP.

Parameters
[in] acmp A pointer to the ACMP peripheral register block.

ACMP_ExternalInputSelect()

void ACMP_ExternalInputSelect ( ACMP_TypeDef * acmp,
ACMP_ExternalInput_Typedef aport
)

Select and enable external input.

This is used when an external module needs to take control of the ACMP POSSEL field to configure the APORT input for the ACMP. Modules, such as LESENSE, use this to change the ACMP input during a scan sequence.

Parameters
[in] acmp A pointer to the ACMP peripheral register block.
[in] aport This parameter decides which APORT(s) the ACMP will use when it's controlled by an external module.

ACMP_GPIOSetup()

void ACMP_GPIOSetup ( ACMP_TypeDef * acmp,
uint32_t location,
bool enable,
bool invert
)

Set up GPIO output from ACMP.

Note
GPIO must be enabled in the CMU before this function call, i.e.,
CMU_ClockEnable(cmuClock_GPIO, true); 
Parameters
[in] acmp A pointer to the ACMP peripheral register block.
location The pin location to use. See the data sheet for location to pin mappings.
enable Enable or disable pin output.
invert Invert output.

ACMP_Init()

void ACMP_Init ( ACMP_TypeDef * acmp,
const ACMP_Init_TypeDef * init
)

Initialize ACMP.

Parameters

[in] init A pointer to the initialization structure used to configure ACMP.

ACMP_Reset()

void ACMP_Reset ( ACMP_TypeDef * acmp )

Reset ACMP to the same state that it was in after a hardware reset.

Note
The GPIO ACMP ROUTE register is NOT reset by this function to allow for centralized setup of this feature.
The peripheral may be enabled and disabled during reset.
Parameters
[in] acmp A pointer to the ACMP peripheral register block.

ACMP_IntEnable()

void ACMP_IntEnable ( ACMP_TypeDef * acmp,
uint32_t flags
)
inline

Enable one or more ACMP interrupts.

Note
Depending on the use, a pending interrupt may already be set prior to enabling the interrupt. Consider using ACMP_IntClear() prior to enabling if a pending interrupt should be ignored.
Parameters
[in] acmp A pointer to the ACMP peripheral register block.
[in] flags ACMP interrupt sources to enable. Use a bitwise logic OR combination of valid interrupt flags for the ACMP module. The flags can be, for instance, ACMP_IEN_EDGE or ACMP_IEN_WARMUP.

Useful for handling more interrupt sources in the same interrupt handler.

Parameters
[in] acmp A pointer to the ACMP peripheral register block.
Note
This function does not clear interrupt flags.
Returns
Pending and enabled ACMP interrupt sources. The return value is the bitwise AND combination of
  • the OR combination of enabled interrupt sources in ACMPx_IEN_nnn register (ACMPx_IEN_nnn) and
  • the OR combination of valid interrupt flags of the ACMP module (ACMPx_IF_nnn).

ACMP_IntSet()

void ACMP_IntSet ( ACMP_TypeDef * acmp,
uint32_t flags
)
inline

Set one or more pending ACMP interrupts from software.

Parameters
[in] acmp A pointer to the ACMP peripheral register block.
[in] flags ACMP interrupt sources to set as pending. Use a bitwise logic OR combination of valid interrupt flags for the ACMP module. The flags can be, for instance, ACMP_IFS_EDGE or ACMP_IFS_WARMUP.
