NYX 0:85b3fd62ea1a 17 ==============================================================================
NYX 0:85b3fd62ea1a 18 ##### DAC Peripheral features #####
NYX 0:85b3fd62ea1a 19 ==============================================================================
NYX 0:85b3fd62ea1a 20 [..]
NYX 0:85b3fd62ea1a 21 *** DAC Channels ***
NYX 0:85b3fd62ea1a 22 ====================
NYX 0:85b3fd62ea1a 23 [..]
NYX 0:85b3fd62ea1a 24 The device integrates two 12-bit Digital Analog Converters that can
NYX 0:85b3fd62ea1a 25 be used independently or simultaneously (dual mode):
NYX 0:85b3fd62ea1a 26 (#) DAC channel1 with DAC_OUT1 (PA4) as output
NYX 0:85b3fd62ea1a 27 (#) DAC channel2 with DAC_OUT2 (PA5) as output
NYX 0:85b3fd62ea1a 28
NYX 0:85b3fd62ea1a 29 *** DAC Triggers ***
NYX 0:85b3fd62ea1a 30 ====================
NYX 0:85b3fd62ea1a 31 [..]
NYX 0:85b3fd62ea1a 32 Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
NYX 0:85b3fd62ea1a 33 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
NYX 0:85b3fd62ea1a 34 [..]
NYX 0:85b3fd62ea1a 35 Digital to Analog conversion can be triggered by:
NYX 0:85b3fd62ea1a 36 (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_TRIGGER_EXT_IT9.
NYX 0:85b3fd62ea1a 37 The used pin (GPIOx_Pin9) must be configured in input mode.
NYX 0:85b3fd62ea1a 38
NYX 0:85b3fd62ea1a 39 (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8
NYX 0:85b3fd62ea1a 40 (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T4_TRGO...)
NYX 0:85b3fd62ea1a 41
NYX 0:85b3fd62ea1a 42 (#) Software using DAC_TRIGGER_SOFTWARE
NYX 0:85b3fd62ea1a 43
NYX 0:85b3fd62ea1a 44 *** DAC Buffer mode feature ***
NYX 0:85b3fd62ea1a 45 ===============================
NYX 0:85b3fd62ea1a 46 [..]
NYX 0:85b3fd62ea1a 47 Each DAC channel integrates an output buffer that can be used to
NYX 0:85b3fd62ea1a 48 reduce the output impedance, and to drive external loads directly
NYX 0:85b3fd62ea1a 49 without having to add an external operational amplifier.
NYX 0:85b3fd62ea1a 50 To enable, the output buffer use
NYX 0:85b3fd62ea1a 51 sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
NYX 0:85b3fd62ea1a 52 [..]
NYX 0:85b3fd62ea1a 53 (@) Refer to the device datasheet for more details about output
NYX 0:85b3fd62ea1a 54 impedance value with and without output buffer.
NYX 0:85b3fd62ea1a 55
NYX 0:85b3fd62ea1a 56 *** DAC wave generation feature ***
NYX 0:85b3fd62ea1a 57 ===================================
NYX 0:85b3fd62ea1a 58 [..]
NYX 0:85b3fd62ea1a 59 Both DAC channels can be used to generate
NYX 0:85b3fd62ea1a 60 (#) Noise wave
NYX 0:85b3fd62ea1a 61 (#) Triangle wave
NYX 0:85b3fd62ea1a 62
NYX 0:85b3fd62ea1a 63 *** DAC data format ***
NYX 0:85b3fd62ea1a 64 =======================
NYX 0:85b3fd62ea1a 65 [..]
NYX 0:85b3fd62ea1a 66 The DAC data format can be:
NYX 0:85b3fd62ea1a 67 (#) 8-bit right alignment using DAC_ALIGN_8B_R
NYX 0:85b3fd62ea1a 68 (#) 12-bit left alignment using DAC_ALIGN_12B_L
NYX 0:85b3fd62ea1a 69 (#) 12-bit right alignment using DAC_ALIGN_12B_R
NYX 0:85b3fd62ea1a 70
NYX 0:85b3fd62ea1a 71 *** DAC data value to voltage correspondence ***
NYX 0:85b3fd62ea1a 72 ================================================
NYX 0:85b3fd62ea1a 73 [..]
NYX 0:85b3fd62ea1a 74 The analog output voltage on each DAC channel pin is determined
NYX 0:85b3fd62ea1a 75 by the following equation:
NYX 0:85b3fd62ea1a 76 DAC_OUTx = VREF+ * DOR / 4095
NYX 0:85b3fd62ea1a 77 with DOR is the Data Output Register
NYX 0:85b3fd62ea1a 78 VEF+ is the input voltage reference (refer to the device datasheet)
NYX 0:85b3fd62ea1a 79 e.g. To set DAC_OUT1 to 0.7V, use
NYX 0:85b3fd62ea1a 80 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
NYX 0:85b3fd62ea1a 81
NYX 0:85b3fd62ea1a 82 *** DMA requests ***
NYX 0:85b3fd62ea1a 83 =====================
NYX 0:85b3fd62ea1a 84 [..]
NYX 0:85b3fd62ea1a 85 A DMA1 request can be generated when an external trigger (but not
NYX 0:85b3fd62ea1a 86 a software trigger) occurs if DMA1 requests are enabled using
NYX 0:85b3fd62ea1a 87 HAL_DAC_Start_DMA()
NYX 0:85b3fd62ea1a 88 [..]
NYX 0:85b3fd62ea1a 89 DMA1 requests are mapped as following:
NYX 0:85b3fd62ea1a 90 (#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be
NYX 0:85b3fd62ea1a 91 already configured
NYX 0:85b3fd62ea1a 92 (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be
NYX 0:85b3fd62ea1a 93 already configured
NYX 0:85b3fd62ea1a 94
NYX 0:85b3fd62ea1a 95 -@- For Dual mode and specific signal (Triangle and noise) generation please
NYX 0:85b3fd62ea1a 96 refer to Extension Features Driver description
NYX 0:85b3fd62ea1a 97

NYX 0:85b3fd62ea1a 100 ==============================================================================
NYX 0:85b3fd62ea1a 101 [..]

NYX 0:85b3fd62ea1a 105 (+) Configure the DAC channel using HAL_DAC_ConfigChannel() function.
NYX 0:85b3fd62ea1a 106 (+) Enable the DAC channel using HAL_DAC_Start() or HAL_DAC_Start_DMA functions
NYX 0:85b3fd62ea1a 107
NYX 0:85b3fd62ea1a 108 *** Polling mode IO operation ***
NYX 0:85b3fd62ea1a 109 =================================

NYX 0:85b3fd62ea1a 117 [..]
NYX 0:85b3fd62ea1a 118 (+) Start the DAC peripheral using HAL_DAC_Start_DMA(), at this stage the user specify the length
NYX 0:85b3fd62ea1a 119 of data to be transferred at each end of conversion
NYX 0:85b3fd62ea1a 120 (+) At The end of data transfer HAL_DAC_ConvCpltCallbackCh1()or HAL_DAC_ConvCpltCallbackCh2()
NYX 0:85b3fd62ea1a 121 function is executed and user can add his own code by customization of function pointer
NYX 0:85b3fd62ea1a 122 HAL_DAC_ConvCpltCallbackCh1 or HAL_DAC_ConvCpltCallbackCh2
NYX 0:85b3fd62ea1a 123 (+) In case of transfer Error, HAL_DAC_ErrorCallbackCh1() function is executed and user can
NYX 0:85b3fd62ea1a 124 add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1
