bogdanm 0:9b334a45a8ff 18 *** DAC Channels ***
bogdanm 0:9b334a45a8ff 19 ====================
bogdanm 0:9b334a45a8ff 20 [..]
bogdanm 0:9b334a45a8ff 21 The device integrates up to 3 12-bit Digital Analog Converters that can
bogdanm 0:9b334a45a8ff 22 be used independently or simultaneously (dual mode):
bogdanm 0:9b334a45a8ff 23 (#) DAC1 channel1 with DAC1_OUT1 (PA4) as output
bogdanm 0:9b334a45a8ff 24 (#) DAC1 channel2 with DAC1_OUT2 (PA5) as output
bogdanm 0:9b334a45a8ff 25 (for STM32F3 devices having 2 channels on DAC1)
bogdanm 0:9b334a45a8ff 26 (#) DAC2 channel1 with DAC2_OUT1 (PA6) as output
bogdanm 0:9b334a45a8ff 27 (for STM32F3 devices having 2 DAC)
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 DAC1_OUT1/DAC1_OUT2/DAC2_OUT1 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_Pin9) using DAC_Trigger_Ext_IT9.
bogdanm 0:9b334a45a8ff 37 The used pin (GPIOx_Pin9) must be configured in input mode.
bogdanm 0:9b334a45a8ff 38
bogdanm 0:9b334a45a8ff 39 (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8
bogdanm 0:9b334a45a8ff 40 (DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...)
bogdanm 0:9b334a45a8ff 41
bogdanm 0:9b334a45a8ff 42 (#) Software using DAC_Trigger_Software
bogdanm 0:9b334a45a8ff 43
bogdanm 0:9b334a45a8ff 44 *** DAC Buffer mode feature ***
bogdanm 0:9b334a45a8ff 45 ===============================
bogdanm 0:9b334a45a8ff 46 [..]
bogdanm 0:9b334a45a8ff 47 Each DAC channel integrates an output buffer that can be used to
bogdanm 0:9b334a45a8ff 48 reduce the output impedance, and to drive external loads directly
bogdanm 0:9b334a45a8ff 49 without having to add an external operational amplifier.
bogdanm 0:9b334a45a8ff 50 To enable, the output buffer use
bogdanm 0:9b334a45a8ff 51 sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
bogdanm 0:9b334a45a8ff 52 [..]
bogdanm 0:9b334a45a8ff 53 (@) Refer to the device datasheet for more details about output
bogdanm 0:9b334a45a8ff 54 impedance value with and without output buffer.
bogdanm 0:9b334a45a8ff 55
bogdanm 0:9b334a45a8ff 56 *** DAC wave generation feature ***
bogdanm 0:9b334a45a8ff 57 ===================================
bogdanm 0:9b334a45a8ff 58 [..]
bogdanm 0:9b334a45a8ff 59 Both DAC channels of DAC1 can be used to generate
bogdanm 0:9b334a45a8ff 60 note that wave generation is not available in DAC2.
bogdanm 0:9b334a45a8ff 61 (#) Noise wave
bogdanm 0:9b334a45a8ff 62 (#) Triangle wave
bogdanm 0:9b334a45a8ff 63
bogdanm 0:9b334a45a8ff 64 Wave generation is NOT available in DAC2.
bogdanm 0:9b334a45a8ff 65
bogdanm 0:9b334a45a8ff 66 *** DAC data format ***
bogdanm 0:9b334a45a8ff 67 =======================
bogdanm 0:9b334a45a8ff 68 [..]
bogdanm 0:9b334a45a8ff 69 The DAC data format can be:
bogdanm 0:9b334a45a8ff 70 (#) 8-bit right alignment using DAC_ALIGN_8B_R
bogdanm 0:9b334a45a8ff 71 (#) 12-bit left alignment using DAC_ALIGN_12B_L
bogdanm 0:9b334a45a8ff 72 (#) 12-bit right alignment using DAC_ALIGN_12B_R
bogdanm 0:9b334a45a8ff 73
bogdanm 0:9b334a45a8ff 74 *** DAC data value to voltage correspondence ***
bogdanm 0:9b334a45a8ff 75 ================================================
bogdanm 0:9b334a45a8ff 76 [..]
bogdanm 0:9b334a45a8ff 77 The analog output voltage on each DAC channel pin is determined
bogdanm 0:9b334a45a8ff 78 by the following equation:
bogdanm 0:9b334a45a8ff 79 DAC_OUTx = VREF+ * DOR / 4095
bogdanm 0:9b334a45a8ff 80 with DOR is the Data Output Register
bogdanm 0:9b334a45a8ff 81 VEF+ is the input voltage reference (refer to the device datasheet)
bogdanm 0:9b334a45a8ff 82 e.g. To set DAC_OUT1 to 0.7V, use
bogdanm 0:9b334a45a8ff 83 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
bogdanm 0:9b334a45a8ff 84
bogdanm 0:9b334a45a8ff 85 *** DMA requests ***
bogdanm 0:9b334a45a8ff 86 =====================
bogdanm 0:9b334a45a8ff 87 [..]
bogdanm 0:9b334a45a8ff 88 A DMA1 or DMA2 request can be generated when an external trigger
bogdanm 0:9b334a45a8ff 89 (but not a software trigger) occurs if DMA1 or DMA2 requests are
bogdanm 0:9b334a45a8ff 90 enabled using HAL_DAC_Start_DMA()
bogdanm 0:9b334a45a8ff 91 [..]
bogdanm 0:9b334a45a8ff 92 DMA1 requests are mapped as following:
bogdanm 0:9b334a45a8ff 93 (#) DAC1 channel1: mapped either on
bogdanm 0:9b334a45a8ff 94 - DMA1 channel3
bogdanm 0:9b334a45a8ff 95 - or DMA2 channel3 (for STM32F3 devices having 2 DMA)
bogdanm 0:9b334a45a8ff 96 which must be already configured
bogdanm 0:9b334a45a8ff 97 (#) DAC1 channel2:
