|
|
<p>The KSDK provides a peripheral driver for the Digital-to-Analog Converter (DAC) module of Kinetis devices.</p>
|
|
<p>#Overview</p>
|
|
<p>The DAC driver includes a basic DAC module (converter) and DAC buffer.</p>
|
|
<p>The basic DAC module supports operations unique to the DAC converter in each DAC instance. The APIs in this part are used in the initialization phase, which is necessary for enabling the DAC module in the application. The APIs enable/disable the clock, enable/disable the module, and configure the converter. Call the initial APIs to prepare the DAC module for the application.</p>
|
|
<p>The DAC buffer operates the DAC hardware buffer. The DAC module supports a hardware buffer to keep a group of DAC values to be converted. This feature supports updating the DAC output value automatically by triggering the buffer read pointer to move in the buffer. Use the APIs to configure the hardware buffer's trigger mode, watermark, work mode, and use size. Additionally, the APIs operate the DMA, interrupts, flags, the pointer (index of buffer), item values, and so on.</p>
|
|
<p>The DAC buffer plays a major part when using the DAC module, as the most functional features are designed for the DAC hardware buffer.</p>
|
|
<h1>Typical use case</h1>
