| 18 | ##### DAC Peripheral features #####
|
---|
| 19 | ==============================================================================
|
---|
| 20 | [..]
|
---|
| 21 | *** DAC Channels ***
|
---|
| 22 | ====================
|
---|
| 23 | [..]
|
---|
| 24 | The device integrates two 12-bit Digital Analog Converters that can
|
---|
| 25 | be used independently or simultaneously (dual mode):
|
---|
| 26 | (#) DAC channel1 with DAC_OUT1 (PA4) as output
|
---|
| 27 | (#) DAC channel2 with DAC_OUT2 (PA5) as output
|
---|
| 28 |
|
---|
| 29 | *** DAC Triggers ***
|
---|
| 30 | ====================
|
---|
| 31 | [..]
|
---|
| 32 | Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
|
---|
| 33 | and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
|
---|
| 34 | [..]
|
---|
| 35 | Digital to Analog conversion can be triggered by:
|
---|
| 36 | (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_TRIGGER_EXT_IT9.
|
---|
| 37 | The used pin (GPIOx_Pin9) must be configured in input mode.
|
---|
| 38 |
|
---|
| 39 | (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8
|
---|
| 40 | (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T4_TRGO...)
|
---|
| 41 |
|
---|
| 42 | (#) Software using DAC_TRIGGER_SOFTWARE
|
---|
| 43 |
|
---|
| 44 | *** DAC Buffer mode feature ***
|
---|
| 45 | ===============================
|
---|
| 46 | [..]
|
---|
| 47 | Each DAC channel integrates an output buffer that can be used to
|
---|
| 48 | reduce the output impedance, and to drive external loads directly
|
---|
| 49 | without having to add an external operational amplifier.
|
---|
| 50 | To enable, the output buffer use
|
---|
| 51 | sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
|
---|
| 52 | [..]
|
---|
| 53 | (@) Refer to the device datasheet for more details about output
|
---|
| 54 | impedance value with and without output buffer.
|
---|
| 55 |
|
---|
| 56 | *** DAC wave generation feature ***
|
---|
| 57 | ===================================
|
---|
| 58 | [..]
|
---|
| 59 | Both DAC channels can be used to generate
|
---|
| 60 | (#) Noise wave
|
---|
| 61 | (#) Triangle wave
|
---|
| 62 |
|
---|
| 63 | *** DAC data format ***
|
---|
| 64 | =======================
|
---|
| 65 | [..]
|
---|
| 66 | The DAC data format can be:
|
---|
| 67 | (#) 8-bit right alignment using DAC_ALIGN_8B_R
|
---|
| 68 | (#) 12-bit left alignment using DAC_ALIGN_12B_L
|
---|
| 69 | (#) 12-bit right alignment using DAC_ALIGN_12B_R
|
---|
| 70 |
|
---|
| 71 | *** DAC data value to voltage correspondence ***
|
---|
| 72 | ================================================
|
---|
| 73 | [..]
|
---|
| 74 | The analog output voltage on each DAC channel pin is determined
|
---|
| 75 | by the following equation:
|
---|
| 76 | DAC_OUTx = VREF+ * DOR / 4095
|
---|
| 77 | with DOR is the Data Output Register
|
---|
| 78 | VEF+ is the input voltage reference (refer to the device datasheet)
|
---|
| 79 | e.g. To set DAC_OUT1 to 0.7V, use
|
---|
| 80 | Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
|
---|
| 81 |
|
---|
| 82 | *** DMA requests ***
|
---|
| 83 | =====================
|
---|
| 84 | [..]
|
---|
| 85 | A DMA1 request can be generated when an external trigger (but not
|
---|
| 86 | a software trigger) occurs if DMA1 requests are enabled using
|
---|
| 87 | HAL_DAC_Start_DMA()
|
---|
| 88 | [..]
|
---|
| 89 | DMA1 requests are mapped as following:
|
---|
| 90 | (#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be
|
---|
| 91 | already configured
|
---|
| 92 | (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be
|
---|
| 93 | already configured
|
---|
| 94 |
|
---|
| 95 | -@- For Dual mode and specific signal (Triangle and noise) generation please
|
---|
| 96 | refer to Extension Features Driver description
|
---|
| 97 |
|
---|
| 98 |
|
---|
| 99 | ##### How to use this driver #####
|
---|
| 100 | ==============================================================================
|
---|
| 101 | [..]
|
---|
| 102 | (+) DAC APB clock must be enabled to get write access to DAC
|
---|
| 103 | registers using HAL_DAC_Init()
|
---|
| 104 | (+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode.
|
---|
| 105 | (+) Configure the DAC channel using HAL_DAC_ConfigChannel() function.
|
---|
| 106 | (+) Enable the DAC channel using HAL_DAC_Start() or HAL_DAC_Start_DMA functions
|
---|
| 107 |
|
---|
| 108 | *** Polling mode IO operation ***
|
---|
| 109 | =================================
|
---|
| 110 | [..]
|
---|
| 111 | (+) Start the DAC peripheral using HAL_DAC_Start()
|
---|
| 112 | (+) To read the DAC last data output value, use the HAL_DAC_GetValue() function.
|
---|
| 113 | (+) Stop the DAC peripheral using HAL_DAC_Stop()
|
---|
| 114 |
|
---|
| 115 | *** DMA mode IO operation ***
|
---|
| 116 | ==============================
|
---|
| 117 | [..]
|
---|
| 118 | (+) Start the DAC peripheral using HAL_DAC_Start_DMA(), at this stage the user specify the length
|
---|
| 119 | of data to be transferred at each end of conversion
|
---|
| 120 | (+) At The end of data transfer HAL_DAC_ConvCpltCallbackCh1()or HAL_DAC_ConvCpltCallbackCh2()
|
---|
| 121 | function is executed and user can add his own code by customization of function pointer
|
---|
| 122 | HAL_DAC_ConvCpltCallbackCh1 or HAL_DAC_ConvCpltCallbackCh2
|
---|
| 123 | (+) In case of transfer Error, HAL_DAC_ErrorCallbackCh1() function is executed and user can
|
---|
| 124 | add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1
|
---|
| 125 | (+) Stop the DAC peripheral using HAL_DAC_Stop_DMA()
|
---|
| 126 |
|
---|
