bogdanm 0:9b334a45a8ff 21 *** DAC Channels ***
bogdanm 0:9b334a45a8ff 22 ====================
bogdanm 0:9b334a45a8ff 23 [..]
bogdanm 0:9b334a45a8ff 24 The device integrates two 12-bit Digital Analog Converters that can
bogdanm 0:9b334a45a8ff 25 be used independently or simultaneously (dual mode):
bogdanm 0:9b334a45a8ff 26 (#) DAC channel1 with DAC_OUT1 (PA4) as output
bogdanm 0:9b334a45a8ff 27 (#) DAC channel2 with DAC_OUT2 (PA5) as output
bogdanm 0:9b334a45a8ff 28
bogdanm 0:9b334a45a8ff 29 *** DAC Triggers ***
bogdanm 0:9b334a45a8ff 30 ====================
bogdanm 0:9b334a45a8ff 31 [..]
bogdanm 0:9b334a45a8ff 32 Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
bogdanm 0:9b334a45a8ff 33 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
bogdanm 0:9b334a45a8ff 34 [..]
bogdanm 0:9b334a45a8ff 35 Digital to Analog conversion can be triggered by:
bogdanm 0:9b334a45a8ff 36 (#) External event: EXTI Line 9 (any GPIOx_PIN_9) using DAC_TRIGGER_EXT_IT9.
bogdanm 0:9b334a45a8ff 37 The used pin (GPIOx_PIN_9) must be configured in input mode.
bogdanm 0:9b334a45a8ff 38
bogdanm 0:9b334a45a8ff 39 (#) Timers TRGO: TIM2, TIM4, TIM6, TIM7
bogdanm 0:9b334a45a8ff 40 For STM32F10x connectivity line devices and STM32F100x devices: TIM3
bogdanm 0:9b334a45a8ff 41 For STM32F10x high-density and XL-density devices: TIM8
bogdanm 0:9b334a45a8ff 42 For STM32F100x high-density value line devices: TIM15 as
bogdanm 0:9b334a45a8ff 43 replacement of TIM5.
bogdanm 0:9b334a45a8ff 44 (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T4_TRGO...)

bogdanm 0:9b334a45a8ff 48 *** DAC Buffer mode feature ***
bogdanm 0:9b334a45a8ff 49 ===============================
bogdanm 0:9b334a45a8ff 50 [..]
bogdanm 0:9b334a45a8ff 51 Each DAC channel integrates an output buffer that can be used to
bogdanm 0:9b334a45a8ff 52 reduce the output impedance, and to drive external loads directly
bogdanm 0:9b334a45a8ff 53 without having to add an external operational amplifier.
bogdanm 0:9b334a45a8ff 54 To enable, the output buffer use
bogdanm 0:9b334a45a8ff 55 sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
bogdanm 0:9b334a45a8ff 56 [..]
bogdanm 0:9b334a45a8ff 57 (@) Refer to the device datasheet for more details about output
bogdanm 0:9b334a45a8ff 58 impedance value with and without output buffer.
bogdanm 0:9b334a45a8ff 59
bogdanm 0:9b334a45a8ff 60 *** DAC connect feature ***
bogdanm 0:9b334a45a8ff 61 ===============================
bogdanm 0:9b334a45a8ff 62 [..]
bogdanm 0:9b334a45a8ff 63 Each DAC channel can be connected internally.
bogdanm 0:9b334a45a8ff 64 To connect, use
bogdanm 0:9b334a45a8ff 65 sConfig.DAC_ConnectOnChipPeripheral = DAC_CHIPCONNECT_ENABLE;
bogdanm 0:9b334a45a8ff 66
bogdanm 0:9b334a45a8ff 67 *** GPIO configurations guidelines ***
bogdanm 0:9b334a45a8ff 68 =====================
bogdanm 0:9b334a45a8ff 69 [..]
bogdanm 0:9b334a45a8ff 70 When a DAC channel is used (ex channel1 on PA4) and the other is not
bogdanm 0:9b334a45a8ff 71 (ex channel1 on PA5 is configured in Analog and disabled).
bogdanm 0:9b334a45a8ff 72 Channel1 may disturb channel2 as coupling effect.
bogdanm 0:9b334a45a8ff 73 Note that there is no coupling on channel2 as soon as channel2 is turned on.
bogdanm 0:9b334a45a8ff 74 Coupling on adjacent channel could be avoided as follows:
bogdanm 0:9b334a45a8ff 75 when unused PA5 is configured as INPUT PULL-UP or DOWN.
bogdanm 0:9b334a45a8ff 76 PA5 is configured in ANALOG just before it is turned on.
bogdanm 0:9b334a45a8ff 77
bogdanm 0:9b334a45a8ff 78 *** DAC wave generation feature ***
bogdanm 0:9b334a45a8ff 79 ===================================
bogdanm 0:9b334a45a8ff 80 [..]
bogdanm 0:9b334a45a8ff 81 Both DAC channels can be used to generate
bogdanm 0:9b334a45a8ff 82 (#) Noise wave using HAL_DACEx_NoiseWaveGenerate()
bogdanm 0:9b334a45a8ff 83 (#) Triangle wave using HAL_DACEx_TriangleWaveGenerate()
bogdanm 0:9b334a45a8ff 84
bogdanm 0:9b334a45a8ff 85 *** DAC data format ***
bogdanm 0:9b334a45a8ff 86 =======================
bogdanm 0:9b334a45a8ff 87 [..]
bogdanm 0:9b334a45a8ff 88 The DAC data format can be:
bogdanm 0:9b334a45a8ff 89 (#) 8-bit right alignment using DAC_ALIGN_8B_R
bogdanm 0:9b334a45a8ff 90 (#) 12-bit left alignment using DAC_ALIGN_12B_L
bogdanm 0:9b334a45a8ff 91 (#) 12-bit right alignment using DAC_ALIGN_12B_R
bogdanm 0:9b334a45a8ff 92
bogdanm 0:9b334a45a8ff 93 *** DAC data value to voltage correspondance ***
bogdanm 0:9b334a45a8ff 94 ================================================
bogdanm 0:9b334a45a8ff 95 [..]
bogdanm 0:9b334a45a8ff 96 The analog output voltage on each DAC channel pin is determined
bogdanm 0:9b334a45a8ff 97 by the following equation:
bogdanm 0:9b334a45a8ff 98 [..]
bogdanm 0:9b334a45a8ff 99 DAC_OUTx = VREF+ * DOR / 4095
bogdanm 0:9b334a45a8ff 100 (+) with DOR is the Data Output Register
bogdanm 0:9b334a45a8ff 101 [..]
bogdanm 0:9b334a45a8ff 102 VEF+ is the input voltage reference (refer to the device datasheet)
bogdanm 0:9b334a45a8ff 103 [..]
bogdanm 0:9b334a45a8ff 104 e.g. To set DAC_OUT1 to 0.7V, use
bogdanm 0:9b334a45a8ff 105 (+) Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
bogdanm 0:9b334a45a8ff 106
bogdanm 0:9b334a45a8ff 107 *** DMA requests ***
bogdanm 0:9b334a45a8ff 108 =====================
bogdanm 0:9b334a45a8ff 109 [..]
bogdanm 0:9b334a45a8ff 110 A DMA1 request can be generated when an external trigger (but not
bogdanm 0:9b334a45a8ff 111 a software trigger) occurs if DMA1 requests are enabled using
bogdanm 0:9b334a45a8ff 112 HAL_DAC_Start_DMA()
bogdanm 0:9b334a45a8ff 113 [..]
bogdanm 0:9b334a45a8ff 114 DMA requests are mapped as following:
bogdanm 0:9b334a45a8ff 115 (#) DAC channel1 :
bogdanm 0:9b334a45a8ff 116 For STM32F100x low-density, medium-density, high-density with DAC

bogdanm 0:9b334a45a8ff 122 mapped on DMA2 channel3 which must be
bogdanm 0:9b334a45a8ff 123 already configured
