phungductung 0:e87aa4c49e95 18 ##### DAC Peripheral features #####
phungductung 0:e87aa4c49e95 19 ==============================================================================
phungductung 0:e87aa4c49e95 20 [..]
phungductung 0:e87aa4c49e95 21 *** DAC Channels ***
phungductung 0:e87aa4c49e95 22 ====================
phungductung 0:e87aa4c49e95 23 [..]
phungductung 0:e87aa4c49e95 24 The device integrates two 12-bit Digital Analog Converters that can
phungductung 0:e87aa4c49e95 25 be used independently or simultaneously (dual mode):
phungductung 0:e87aa4c49e95 26 (#) DAC channel1 with DAC_OUT1 (PA4) as output
phungductung 0:e87aa4c49e95 27 (#) DAC channel2 with DAC_OUT2 (PA5) as output
phungductung 0:e87aa4c49e95 28
phungductung 0:e87aa4c49e95 29 *** DAC Triggers ***
phungductung 0:e87aa4c49e95 30 ====================
phungductung 0:e87aa4c49e95 31 [..]
phungductung 0:e87aa4c49e95 32 Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
phungductung 0:e87aa4c49e95 33 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
phungductung 0:e87aa4c49e95 34 [..]
phungductung 0:e87aa4c49e95 35 Digital to Analog conversion can be triggered by:
phungductung 0:e87aa4c49e95 36 (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_TRIGGER_EXT_IT9.
phungductung 0:e87aa4c49e95 37 The used pin (GPIOx_Pin9) must be configured in input mode.
phungductung 0:e87aa4c49e95 38
phungductung 0:e87aa4c49e95 39 (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8
phungductung 0:e87aa4c49e95 40 (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T4_TRGO...)
phungductung 0:e87aa4c49e95 41
phungductung 0:e87aa4c49e95 42 (#) Software using DAC_TRIGGER_SOFTWARE
phungductung 0:e87aa4c49e95 43
phungductung 0:e87aa4c49e95 44 *** DAC Buffer mode feature ***
phungductung 0:e87aa4c49e95 45 ===============================
phungductung 0:e87aa4c49e95 46 [..]
phungductung 0:e87aa4c49e95 47 Each DAC channel integrates an output buffer that can be used to
phungductung 0:e87aa4c49e95 48 reduce the output impedance, and to drive external loads directly
phungductung 0:e87aa4c49e95 49 without having to add an external operational amplifier.
phungductung 0:e87aa4c49e95 50 To enable, the output buffer use
phungductung 0:e87aa4c49e95 51 sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
phungductung 0:e87aa4c49e95 52 [..]
phungductung 0:e87aa4c49e95 53 (@) Refer to the device datasheet for more details about output
phungductung 0:e87aa4c49e95 54 impedance value with and without output buffer.
phungductung 0:e87aa4c49e95 55
phungductung 0:e87aa4c49e95 56 *** DAC wave generation feature ***
phungductung 0:e87aa4c49e95 57 ===================================
phungductung 0:e87aa4c49e95 58 [..]
phungductung 0:e87aa4c49e95 59 Both DAC channels can be used to generate
phungductung 0:e87aa4c49e95 60 (#) Noise wave using HAL_DACEx_NoiseWaveGenerate()
phungductung 0:e87aa4c49e95 61 (#) Triangle wave using HAL_DACEx_TriangleWaveGenerate()
phungductung 0:e87aa4c49e95 62
phungductung 0:e87aa4c49e95 63 *** DAC data format ***
phungductung 0:e87aa4c49e95 64 =======================
phungductung 0:e87aa4c49e95 65 [..]
phungductung 0:e87aa4c49e95 66 The DAC data format can be:
phungductung 0:e87aa4c49e95 67 (#) 8-bit right alignment using DAC_ALIGN_8B_R
phungductung 0:e87aa4c49e95 68 (#) 12-bit left alignment using DAC_ALIGN_12B_L
phungductung 0:e87aa4c49e95 69 (#) 12-bit right alignment using DAC_ALIGN_12B_R
phungductung 0:e87aa4c49e95 70
phungductung 0:e87aa4c49e95 71 *** DAC data value to voltage correspondence ***
phungductung 0:e87aa4c49e95 72 ================================================
phungductung 0:e87aa4c49e95 73 [..]
phungductung 0:e87aa4c49e95 74 The analog output voltage on each DAC channel pin is determined
phungductung 0:e87aa4c49e95 75 by the following equation:
phungductung 0:e87aa4c49e95 76 DAC_OUTx = VREF+ * DOR / 4095
phungductung 0:e87aa4c49e95 77 with DOR is the Data Output Register
phungductung 0:e87aa4c49e95 78 VEF+ is the input voltage reference (refer to the device datasheet)
phungductung 0:e87aa4c49e95 79 e.g. To set DAC_OUT1 to 0.7V, use
phungductung 0:e87aa4c49e95 80 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
phungductung 0:e87aa4c49e95 81
phungductung 0:e87aa4c49e95 82 *** DMA requests ***
phungductung 0:e87aa4c49e95 83 =====================
phungductung 0:e87aa4c49e95 84 [..]
phungductung 0:e87aa4c49e95 85 A DMA1 request can be generated when an external trigger (but not
phungductung 0:e87aa4c49e95 86 a software trigger) occurs if DMA1 requests are enabled using
phungductung 0:e87aa4c49e95 87 HAL_DAC_Start_DMA()
phungductung 0:e87aa4c49e95 88 [..]
phungductung 0:e87aa4c49e95 89 DMA1 requests are mapped as following:
phungductung 0:e87aa4c49e95 90 (#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be
phungductung 0:e87aa4c49e95 91 already configured
phungductung 0:e87aa4c49e95 92 (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be
phungductung 0:e87aa4c49e95 93 already configured
phungductung 0:e87aa4c49e95 94
phungductung 0:e87aa4c49e95 95 -@- For Dual mode and specific signal (Triangle and noise) generation please
phungductung 0:e87aa4c49e95 96 refer to Extension Features Driver description
