sahilmgandhi 18:6a4db94011d3 18 ##### DAC Peripheral features #####
sahilmgandhi 18:6a4db94011d3 19 ==============================================================================
sahilmgandhi 18:6a4db94011d3 20 [..]
sahilmgandhi 18:6a4db94011d3 21 *** DAC Channels ***
sahilmgandhi 18:6a4db94011d3 22 ====================
sahilmgandhi 18:6a4db94011d3 23 [..]
sahilmgandhi 18:6a4db94011d3 24 The device integrates two 12-bit Digital Analog Converters that can
sahilmgandhi 18:6a4db94011d3 25 be used independently or simultaneously (dual mode):
sahilmgandhi 18:6a4db94011d3 26 (#) DAC channel1 with DAC_OUT1 (PA4) as output
sahilmgandhi 18:6a4db94011d3 27 (#) DAC channel2 with DAC_OUT2 (PA5) as output
sahilmgandhi 18:6a4db94011d3 28
sahilmgandhi 18:6a4db94011d3 29 *** DAC Triggers ***
sahilmgandhi 18:6a4db94011d3 30 ====================
sahilmgandhi 18:6a4db94011d3 31 [..]
sahilmgandhi 18:6a4db94011d3 32 Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
sahilmgandhi 18:6a4db94011d3 33 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
sahilmgandhi 18:6a4db94011d3 34 [..]
sahilmgandhi 18:6a4db94011d3 35 Digital to Analog conversion can be triggered by:
sahilmgandhi 18:6a4db94011d3 36 (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_TRIGGER_EXT_IT9.
sahilmgandhi 18:6a4db94011d3 37 The used pin (GPIOx_Pin9) must be configured in input mode.
sahilmgandhi 18:6a4db94011d3 38
sahilmgandhi 18:6a4db94011d3 39 (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8
sahilmgandhi 18:6a4db94011d3 40 (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T4_TRGO...)
sahilmgandhi 18:6a4db94011d3 41
sahilmgandhi 18:6a4db94011d3 42 (#) Software using DAC_TRIGGER_SOFTWARE
sahilmgandhi 18:6a4db94011d3 43
sahilmgandhi 18:6a4db94011d3 44 *** DAC Buffer mode feature ***
sahilmgandhi 18:6a4db94011d3 45 ===============================
sahilmgandhi 18:6a4db94011d3 46 [..]
sahilmgandhi 18:6a4db94011d3 47 Each DAC channel integrates an output buffer that can be used to
sahilmgandhi 18:6a4db94011d3 48 reduce the output impedance, and to drive external loads directly
sahilmgandhi 18:6a4db94011d3 49 without having to add an external operational amplifier.
sahilmgandhi 18:6a4db94011d3 50 To enable, the output buffer use
sahilmgandhi 18:6a4db94011d3 51 sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
sahilmgandhi 18:6a4db94011d3 52 [..]
sahilmgandhi 18:6a4db94011d3 53 (@) Refer to the device datasheet for more details about output
sahilmgandhi 18:6a4db94011d3 54 impedance value with and without output buffer.

sahilmgandhi 18:6a4db94011d3 56 *** DAC wave generation feature ***
sahilmgandhi 18:6a4db94011d3 57 ===================================
sahilmgandhi 18:6a4db94011d3 58 [..]
sahilmgandhi 18:6a4db94011d3 59 Both DAC channels can be used to generate
sahilmgandhi 18:6a4db94011d3 60 (#) Noise wave
sahilmgandhi 18:6a4db94011d3 61 (#) Triangle wave
sahilmgandhi 18:6a4db94011d3 62
sahilmgandhi 18:6a4db94011d3 63 *** DAC data format ***
sahilmgandhi 18:6a4db94011d3 64 =======================
sahilmgandhi 18:6a4db94011d3 65 [..]
sahilmgandhi 18:6a4db94011d3 66 The DAC data format can be:
sahilmgandhi 18:6a4db94011d3 67 (#) 8-bit right alignment using DAC_ALIGN_8B_R
sahilmgandhi 18:6a4db94011d3 68 (#) 12-bit left alignment using DAC_ALIGN_12B_L
sahilmgandhi 18:6a4db94011d3 69 (#) 12-bit right alignment using DAC_ALIGN_12B_R
sahilmgandhi 18:6a4db94011d3 70
sahilmgandhi 18:6a4db94011d3 71 *** DAC data value to voltage correspondence ***
sahilmgandhi 18:6a4db94011d3 72 ================================================
sahilmgandhi 18:6a4db94011d3 73 [..]
sahilmgandhi 18:6a4db94011d3 74 The analog output voltage on each DAC channel pin is determined
sahilmgandhi 18:6a4db94011d3 75 by the following equation:
sahilmgandhi 18:6a4db94011d3 76 DAC_OUTx = VREF+ * DOR / 4095
sahilmgandhi 18:6a4db94011d3 77 with DOR is the Data Output Register
sahilmgandhi 18:6a4db94011d3 78 VEF+ is the input voltage reference (refer to the device datasheet)
sahilmgandhi 18:6a4db94011d3 79 e.g. To set DAC_OUT1 to 0.7V, use
sahilmgandhi 18:6a4db94011d3 80 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
sahilmgandhi 18:6a4db94011d3 81
sahilmgandhi 18:6a4db94011d3 82 *** DMA requests ***
sahilmgandhi 18:6a4db94011d3 83 =====================
sahilmgandhi 18:6a4db94011d3 84 [..]
sahilmgandhi 18:6a4db94011d3 85 A DMA1 request can be generated when an external trigger (but not
sahilmgandhi 18:6a4db94011d3 86 a software trigger) occurs if DMA1 requests are enabled using
sahilmgandhi 18:6a4db94011d3 87 HAL_DAC_Start_DMA()
sahilmgandhi 18:6a4db94011d3 88 [..]
sahilmgandhi 18:6a4db94011d3 89 DMA1 requests are mapped as following:
sahilmgandhi 18:6a4db94011d3 90 (#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be
sahilmgandhi 18:6a4db94011d3 91 already configured
sahilmgandhi 18:6a4db94011d3 92 (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be
sahilmgandhi 18:6a4db94011d3 93 already configured
sahilmgandhi 18:6a4db94011d3 94
