| mbed_official | 15:a81a8d6c1dfe | 84 | * \section asfdoc_sam0_dac_module_overview Module Overview |
| mbed_official | 15:a81a8d6c1dfe | 85 | * |
| mbed_official | 15:a81a8d6c1dfe | 86 | * The Digital-to-Analog converter converts a digital value to analog voltage. |
| mbed_official | 15:a81a8d6c1dfe | 87 | * The SAM DAC module has one channel with 10-bit resolution, |
| mbed_official | 15:a81a8d6c1dfe | 88 | * and is capable of converting up to 350k samples per second (ksps). |
| mbed_official | 15:a81a8d6c1dfe | 89 | * |
| mbed_official | 15:a81a8d6c1dfe | 90 | * A common use of DAC is to generate audio signals by connecting the DAC |
| mbed_official | 15:a81a8d6c1dfe | 91 | * output to a speaker, or to generate a reference voltage; either for an |
| mbed_official | 15:a81a8d6c1dfe | 92 | * external circuit or an internal peripheral such as the Analog Comparator. |
| mbed_official | 15:a81a8d6c1dfe | 93 | * |
| mbed_official | 15:a81a8d6c1dfe | 94 | * After being set up, the DAC will convert new digital values written to the |
| mbed_official | 15:a81a8d6c1dfe | 95 | * conversion data register (DATA) to an analog value either on the VOUT pin of |
| mbed_official | 15:a81a8d6c1dfe | 96 | * the device, or internally for use as an input to the AC, ADC, and other analog |
| mbed_official | 15:a81a8d6c1dfe | 97 | * modules. |
| mbed_official | 15:a81a8d6c1dfe | 98 | * |
| mbed_official | 15:a81a8d6c1dfe | 99 | * Writing the DATA register will start a new conversion. It is also possible |
| mbed_official | 15:a81a8d6c1dfe | 100 | * to trigger the conversion from the event system. |
| mbed_official | 15:a81a8d6c1dfe | 101 | * |
| mbed_official | 15:a81a8d6c1dfe | 102 | * A simplified block diagram of the DAC can be seen in |
| mbed_official | 15:a81a8d6c1dfe | 103 | * \ref asfdoc_sam0_dac_module_block_diagram "the figure below". |

| mbed_official | 15:a81a8d6c1dfe | 108 | * \subsection asfdoc_sam0_dac_conversion_range Conversion Range |
| mbed_official | 15:a81a8d6c1dfe | 109 | * The conversion range is between GND and the selected voltage reference. |
| mbed_official | 15:a81a8d6c1dfe | 110 | * Available voltage references are: |
| mbed_official | 15:a81a8d6c1dfe | 111 | * \li AVCC voltage reference |
| mbed_official | 15:a81a8d6c1dfe | 112 | * \li Internal 1V reference (INT1V) |
| mbed_official | 15:a81a8d6c1dfe | 113 | * \li External voltage reference (AREF) |
| mbed_official | 15:a81a8d6c1dfe | 114 | * |
| mbed_official | 15:a81a8d6c1dfe | 115 | * \note Internal references will be enabled by the driver, but not disabled. |
| mbed_official | 15:a81a8d6c1dfe | 116 | * Any reference not used by the application should be disabled by the application. |
| mbed_official | 15:a81a8d6c1dfe | 117 | * |
| mbed_official | 15:a81a8d6c1dfe | 118 | * The output voltage from a DAC channel is given as: |
| mbed_official | 15:a81a8d6c1dfe | 119 | * \f[ |
| mbed_official | 15:a81a8d6c1dfe | 120 | * V_{OUT} = \frac{DATA}{0x3FF} \times VREF |
| mbed_official | 15:a81a8d6c1dfe | 121 | * \f] |
| mbed_official | 15:a81a8d6c1dfe | 122 | * |
| mbed_official | 15:a81a8d6c1dfe | 123 | * \subsection asfdoc_sam0_dac_conversion Conversion |
| mbed_official | 15:a81a8d6c1dfe | 124 | * The digital value written to the conversion data register (DATA) will be |
| mbed_official | 15:a81a8d6c1dfe | 125 | * converted to an analog value. |
| mbed_official | 15:a81a8d6c1dfe | 126 | * Writing the DATA register will start a new conversion. |
| mbed_official | 15:a81a8d6c1dfe | 127 | * It is also possible to write the conversion data to the DATABUF register, |
| mbed_official | 15:a81a8d6c1dfe | 128 | * the writing of the DATA register can then be triggered from the event |
| mbed_official | 15:a81a8d6c1dfe | 129 | * system, which will load the value from DATABUF to DATA. |
| mbed_official | 15:a81a8d6c1dfe | 130 | * |
| mbed_official | 15:a81a8d6c1dfe | 131 | * \subsection asfdoc_sam0_dac_analog_output Analog Output |
| mbed_official | 15:a81a8d6c1dfe | 132 | * The analog output value can be output to either the VOUT pin or internally, |
| mbed_official | 15:a81a8d6c1dfe | 133 | * but not both at the same time. |
| mbed_official | 15:a81a8d6c1dfe | 134 | * |
| mbed_official | 15:a81a8d6c1dfe | 135 | * \subsubsection asfdoc_sam0_dac_analog_output_external External Output |
| mbed_official | 15:a81a8d6c1dfe | 136 | * The output buffer must be enabled in order to drive the DAC output to the |
| mbed_official | 15:a81a8d6c1dfe | 137 | * VOUT pin. Due to the output buffer, the DAC has high drive strength, and is |
| mbed_official | 15:a81a8d6c1dfe | 138 | * capable of driving both resistive and capacitive loads, as well as loads |
| mbed_official | 15:a81a8d6c1dfe | 139 | * which combine both. |
| mbed_official | 15:a81a8d6c1dfe | 140 | * |
| mbed_official | 15:a81a8d6c1dfe | 141 | * \subsubsection asfdoc_sam0_dac_analog_output_internal Internal Output |
| mbed_official | 15:a81a8d6c1dfe | 142 | * The analog value can be internally available for use as input to the |
| mbed_official | 15:a81a8d6c1dfe | 143 | * AC or ADC modules. |
| mbed_official | 15:a81a8d6c1dfe | 144 | * |
| mbed_official | 15:a81a8d6c1dfe | 145 | * \subsection asfdoc_sam0_dac_events Events |
| mbed_official | 15:a81a8d6c1dfe | 146 | * Events generation and event actions are configurable in the DAC. |
| mbed_official | 15:a81a8d6c1dfe | 147 | * The DAC has one event line input and one event output: <i>Start Conversion</i> |
| mbed_official | 15:a81a8d6c1dfe | 148 | * and <i>Data Buffer Empty</i>. |
| mbed_official | 15:a81a8d6c1dfe | 149 | * |
| mbed_official | 15:a81a8d6c1dfe | 150 | * If the Start Conversion input event is enabled in the module configuration, |
| mbed_official | 15:a81a8d6c1dfe | 151 | * an incoming event will load data from the data buffer to the data register |
| mbed_official | 15:a81a8d6c1dfe | 152 | * and start a new conversion. This method synchronizes conversions with |
| mbed_official | 15:a81a8d6c1dfe | 153 | * external events (such as those from a timer module) and ensures regular and |
| mbed_official | 15:a81a8d6c1dfe | 154 | * fixed conversion intervals. |
| mbed_official | 15:a81a8d6c1dfe | 155 | * |
| mbed_official | 15:a81a8d6c1dfe | 156 | * If the Data Buffer Empty output event is enabled in the module configuration, |
| mbed_official | 15:a81a8d6c1dfe | 157 | * events will be generated when the DAC data buffer register becomes empty and |
| mbed_official | 15:a81a8d6c1dfe | 158 | * new data can be loaded to the buffer. |
| mbed_official | 15:a81a8d6c1dfe | 159 | * |
| mbed_official | 15:a81a8d6c1dfe | 160 | * \note The connection of events between modules requires the use of the |
| mbed_official | 15:a81a8d6c1dfe | 161 | * \ref asfdoc_sam0_events_group "SAM Event System Driver (EVENTS)" |
| mbed_official | 15:a81a8d6c1dfe | 162 | * to route output event of one module to the the input event of another. |
| mbed_official | 15:a81a8d6c1dfe | 163 | * For more information on event routing, refer to the event driver |
| mbed_official | 15:a81a8d6c1dfe | 164 | * documentation. |
| mbed_official | 15:a81a8d6c1dfe | 165 | * |
| mbed_official | 15:a81a8d6c1dfe | 166 | * \subsection asfdoc_sam0_dac_data_adjust Left and Right Adjusted Values |
| mbed_official | 15:a81a8d6c1dfe | 167 | * The 10-bit input value to the DAC is contained in a 16-bit register. This |
| mbed_official | 15:a81a8d6c1dfe | 168 | * can be configured to be either left or right adjusted. In |
| mbed_official | 15:a81a8d6c1dfe | 169 | * \ref asfdoc_sam0_dac_module_adj_modes "the figure below" both options are |
| mbed_official | 15:a81a8d6c1dfe | 170 | * shown, and the position of the most (MSB) and the least (LSB) significant bits |
| mbed_official | 15:a81a8d6c1dfe | 171 | * are indicated. The unused bits should always be written to zero. |

| mbed_official | 15:a81a8d6c1dfe | 262 | * The clock for the DAC interface (CLK_DAC) is generated by the Power Manager. |
| mbed_official | 15:a81a8d6c1dfe | 263 | * This clock is turned on by default, and can be enabled and disabled in the |
| mbed_official | 15:a81a8d6c1dfe | 264 | * Power Manager. |
| mbed_official | 15:a81a8d6c1dfe | 265 | * |
| mbed_official | 15:a81a8d6c1dfe | 266 | * Additionally, an asynchronous clock source (GCLK_DAC) is required. |
| mbed_official | 15:a81a8d6c1dfe | 267 | * These clocks are normally disabled by default. The selected clock source |
| mbed_official | 15:a81a8d6c1dfe | 268 | * must be enabled in the Power Manager before it can be used by the DAC. |
| mbed_official | 15:a81a8d6c1dfe | 269 | * The DAC core operates asynchronously from the user interface and |
| mbed_official | 15:a81a8d6c1dfe | 270 | * peripheral bus. As a consequence, the DAC needs two clock cycles of both |
| mbed_official | 15:a81a8d6c1dfe | 271 | * CLK_DAC and GCLK_DAC to synchronize the values written to some of the |
| mbed_official | 15:a81a8d6c1dfe | 272 | * control and data registers. |
| mbed_official | 15:a81a8d6c1dfe | 273 | * The oscillator source for the GCLK_DAC clock is selected in the System |
| mbed_official | 15:a81a8d6c1dfe | 274 | * Control Interface (SCIF). |

| mbed_official | 15:a81a8d6c1dfe | 281 | * sleep mode. Therefore, always make sure that the output buffer is not |
| mbed_official | 15:a81a8d6c1dfe | 282 | * enabled when it is not needed, to ensure minimum power consumption. |

| mbed_official | 15:a81a8d6c1dfe | 286 | * data is not written to the DAC before the last conversion is complete. |
| mbed_official | 15:a81a8d6c1dfe | 287 | * Conversions should be triggered by a periodic event from a Timer/Counter or |
