bogdanm 0:9b334a45a8ff 21 *** DAC Channels ***
bogdanm 0:9b334a45a8ff 22 ====================
bogdanm 0:9b334a45a8ff 23 [..]
bogdanm 0:9b334a45a8ff 24 STM32F0 devices integrates no, one or two 12-bit Digital Analog Converters.
bogdanm 0:9b334a45a8ff 25 STM32F05x devices have one converter (channel1)
bogdanm 0:9b334a45a8ff 26 STM32F07x & STM32F09x devices have two converters (i.e. channel1 & channel2)
bogdanm 0:9b334a45a8ff 27
bogdanm 0:9b334a45a8ff 28 When 2 converters are present (i.e. channel1 & channel2) they
bogdanm 0:9b334a45a8ff 29 can be used independently or simultaneously (dual mode):
bogdanm 0:9b334a45a8ff 30 (#) DAC channel1 with DAC_OUT1 (PA4) as output
bogdanm 0:9b334a45a8ff 31 (#) DAC channel2 with DAC_OUT2 (PA5) as output
bogdanm 0:9b334a45a8ff 32
bogdanm 0:9b334a45a8ff 33 *** DAC Triggers ***
bogdanm 0:9b334a45a8ff 34 ====================
bogdanm 0:9b334a45a8ff 35 [..]
bogdanm 0:9b334a45a8ff 36 Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
bogdanm 0:9b334a45a8ff 37 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
bogdanm 0:9b334a45a8ff 38 [..]
bogdanm 0:9b334a45a8ff 39 Digital to Analog conversion can be triggered by:
bogdanm 0:9b334a45a8ff 40 (#) External event: EXTI Line 9 (any GPIOx_PIN_9) using DAC_TRIGGER_EXT_IT9.
bogdanm 0:9b334a45a8ff 41 The used pin (GPIOx_PIN_9) must be configured in input mode.
bogdanm 0:9b334a45a8ff 42
bogdanm 0:9b334a45a8ff 43 (#) Timers TRGO: TIM2, TIM3, TIM6, and TIM15
bogdanm 0:9b334a45a8ff 44 (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T3_TRGO...)
bogdanm 0:9b334a45a8ff 45
bogdanm 0:9b334a45a8ff 46 (#) Software using DAC_TRIGGER_SOFTWARE
bogdanm 0:9b334a45a8ff 47
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 *** GPIO configurations guidelines ***
bogdanm 0:9b334a45a8ff 61 =====================
bogdanm 0:9b334a45a8ff 62 [..]
bogdanm 0:9b334a45a8ff 63 When a DAC channel is used (ex channel1 on PA4) and the other is not
bogdanm 0:9b334a45a8ff 64 (ex channel1 on PA5 is configured in Analog and disabled).
bogdanm 0:9b334a45a8ff 65 Channel1 may disturb channel2 as coupling effect.
bogdanm 0:9b334a45a8ff 66 Note that there is no coupling on channel2 as soon as channel2 is turned on.
bogdanm 0:9b334a45a8ff 67 Coupling on adjacent channel could be avoided as follows:
bogdanm 0:9b334a45a8ff 68 when unused PA5 is configured as INPUT PULL-UP or DOWN.
bogdanm 0:9b334a45a8ff 69 PA5 is configured in ANALOG just before it is turned on.
bogdanm 0:9b334a45a8ff 70
bogdanm 0:9b334a45a8ff 71 *** DAC wave generation feature ***
bogdanm 0:9b334a45a8ff 72 ===================================
bogdanm 0:9b334a45a8ff 73 [..]
bogdanm 0:9b334a45a8ff 74 Both DAC channels can be used to generate
bogdanm 0:9b334a45a8ff 75 (#) Noise wave
bogdanm 0:9b334a45a8ff 76 (#) Triangle wave
bogdanm 0:9b334a45a8ff 77
bogdanm 0:9b334a45a8ff 78 *** DAC data format ***
bogdanm 0:9b334a45a8ff 79 =======================
bogdanm 0:9b334a45a8ff 80 [..]
bogdanm 0:9b334a45a8ff 81 The DAC data format can be:
bogdanm 0:9b334a45a8ff 82 (#) 8-bit right alignment using DAC_ALIGN_8B_R
bogdanm 0:9b334a45a8ff 83 (#) 12-bit left alignment using DAC_ALIGN_12B_L
bogdanm 0:9b334a45a8ff 84 (#) 12-bit right alignment using DAC_ALIGN_12B_R
bogdanm 0:9b334a45a8ff 85
bogdanm 0:9b334a45a8ff 86 *** DAC data value to voltage correspondance ***
bogdanm 0:9b334a45a8ff 87 ================================================
bogdanm 0:9b334a45a8ff 88 [..]
bogdanm 0:9b334a45a8ff 89 The analog output voltage on each DAC channel pin is determined
bogdanm 0:9b334a45a8ff 90 by the following equation:
bogdanm 0:9b334a45a8ff 91 [..]
bogdanm 0:9b334a45a8ff 92 DAC_OUTx = VREF+ * DOR / 4095
bogdanm 0:9b334a45a8ff 93 (+) with DOR is the Data Output Register
bogdanm 0:9b334a45a8ff 94 [..]
bogdanm 0:9b334a45a8ff 95 VEF+ is the input voltage reference (refer to the device datasheet)
bogdanm 0:9b334a45a8ff 96 [..]
bogdanm 0:9b334a45a8ff 97 e.g. To set DAC_OUT1 to 0.7V, use
bogdanm 0:9b334a45a8ff 98 (+) Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
bogdanm 0:9b334a45a8ff 99
bogdanm 0:9b334a45a8ff 100 *** DMA requests ***
bogdanm 0:9b334a45a8ff 101 =====================
bogdanm 0:9b334a45a8ff 102 [..]
bogdanm 0:9b334a45a8ff 103 A DMA1 request can be generated when an external trigger (but not
bogdanm 0:9b334a45a8ff 104 a software trigger) occurs if DMA1 requests are enabled using
bogdanm 0:9b334a45a8ff 105 HAL_DAC_Start_DMA()
bogdanm 0:9b334a45a8ff 106 [..]
bogdanm 0:9b334a45a8ff 107 DMA1 requests are mapped as following:
bogdanm 0:9b334a45a8ff 108 (#) DAC channel1 : mapped on DMA1 channel3 which must be
bogdanm 0:9b334a45a8ff 109 already configured
bogdanm 0:9b334a45a8ff 110 (#) DAC channel2 : mapped on DMA1 channel4 which must be
bogdanm 0:9b334a45a8ff 111 already configured
bogdanm 0:9b334a45a8ff 112
bogdanm 0:9b334a45a8ff 113 (@) For Dual mode and specific signal (Triangle and noise) generation please
bogdanm 0:9b334a45a8ff 114 refer to Extended Features Driver description
bogdanm 0:9b334a45a8ff 115 STM32F0 devices with one channel (one converting capability) does not
bogdanm 0:9b334a45a8ff 116 support Dual mode and specific signal (Triangle and noise) generation.
