Overview

The MCUXpresso SDK provides a driver for the Digital Analog Converter (DAC) module of MCUXpreeso SDK devices.

Based on the features of the DAC module, the DAC driver is divided into serval function groups.

Module Initialization Interfaces

The functions in this group can be used to initialize or de-initialize the DAC module. To initialize the DAC module, the function DAC_GetDefaultConfig() can be invoked to get the module's default configuration.

Channels Control Interfaces

This function group contains channel control APIs. To configure the channels' all options directly at one time, the function DAC_SetChannelConfig() is provided, this function takes the pointer to structure that in the type of dac_channel_config_t as the parameter. All channel-related options are covered in this structure type. To set some specific options of channels, some low-level APIs also provided in this function group. All APIs in this function group take channelMask as the parameter, it means the mask of channel ID. If both channel A and channel B are aimed to set the same options, then users just need to invoke related APIs once with the channelMask set as the OR'ed value of channel A and channel B.

Triangle Waveform Configuration Interface

There is only one API in this function group, it is DAC_SetTriangleConfig() function. This function is used to configure the triangle waveform when channel A's wave type is selected as the triangle type.

Interrupts Control Interfaces.

The APIs in this function group can be used to enable/disable interrupts.

Status Flags Control Interfaces

The APIs in this function group can be used to get/clear status flags.
