bogdanm 0:9b334a45a8ff 17 ==============================================================================
bogdanm 0:9b334a45a8ff 18 ##### DAC Peripheral features #####
bogdanm 0:9b334a45a8ff 19 ==============================================================================
bogdanm 0:9b334a45a8ff 20 [..]
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_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 can be used to generate
bogdanm 0:9b334a45a8ff 60 (#) Noise wave using HAL_DACEx_NoiseWaveGenerate()
bogdanm 0:9b334a45a8ff 61 (#) Triangle wave using HAL_DACEx_TriangleWaveGenerate()
bogdanm 0:9b334a45a8ff 62
bogdanm 0:9b334a45a8ff 63 *** DAC data format ***
bogdanm 0:9b334a45a8ff 64 =======================
bogdanm 0:9b334a45a8ff 65 [..]
bogdanm 0:9b334a45a8ff 66 The DAC data format can be:
bogdanm 0:9b334a45a8ff 67 (#) 8-bit right alignment using DAC_ALIGN_8B_R
bogdanm 0:9b334a45a8ff 68 (#) 12-bit left alignment using DAC_ALIGN_12B_L
bogdanm 0:9b334a45a8ff 69 (#) 12-bit right alignment using DAC_ALIGN_12B_R
bogdanm 0:9b334a45a8ff 70
bogdanm 0:9b334a45a8ff 71 *** DAC data value to voltage correspondence ***
bogdanm 0:9b334a45a8ff 72 ================================================
bogdanm 0:9b334a45a8ff 73 [..]
bogdanm 0:9b334a45a8ff 74 The analog output voltage on each DAC channel pin is determined
bogdanm 0:9b334a45a8ff 75 by the following equation:
bogdanm 0:9b334a45a8ff 76 DAC_OUTx = VREF+ * DOR / 4095
bogdanm 0:9b334a45a8ff 77 with DOR is the Data Output Register
bogdanm 0:9b334a45a8ff 78 VEF+ is the input voltage reference (refer to the device datasheet)
bogdanm 0:9b334a45a8ff 79 e.g. To set DAC_OUT1 to 0.7V, use
bogdanm 0:9b334a45a8ff 80 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
bogdanm 0:9b334a45a8ff 81
bogdanm 0:9b334a45a8ff 82 *** DMA requests ***
bogdanm 0:9b334a45a8ff 83 =====================
bogdanm 0:9b334a45a8ff 84 [..]
bogdanm 0:9b334a45a8ff 85 A DMA1 request can be generated when an external trigger (but not
bogdanm 0:9b334a45a8ff 86 a software trigger) occurs if DMA1 requests are enabled using
bogdanm 0:9b334a45a8ff 87 HAL_DAC_Start_DMA()
bogdanm 0:9b334a45a8ff 88 [..]
bogdanm 0:9b334a45a8ff 89 DMA1 requests are mapped as following:
bogdanm 0:9b334a45a8ff 90 (#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be
bogdanm 0:9b334a45a8ff 91 already configured
bogdanm 0:9b334a45a8ff 92 (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be
bogdanm 0:9b334a45a8ff 93 already configured
bogdanm 0:9b334a45a8ff 94
bogdanm 0:9b334a45a8ff 95 -@- For Dual mode and specific signal (Triangle and noise) generation please
