mbed_official 340:28d1f895c6fe 22 ====================
mbed_official 340:28d1f895c6fe 23 [..]
mbed_official 340:28d1f895c6fe 24 STM32F0 devices integrates no, one or two 12-bit Digital Analog Converters.
mbed_official 340:28d1f895c6fe 25 STM32F05x devices have one converter (channel1)
mbed_official 340:28d1f895c6fe 26 STM32F07x & STM32F09x devices have two converters (i.e. channel1 & channel2)
mbed_official 340:28d1f895c6fe 27
mbed_official 340:28d1f895c6fe 28 When 2 converters are present (i.e. channel1 & channel2) they
mbed_official 340:28d1f895c6fe 29 can be used independently or simultaneously (dual mode):
mbed_official 340:28d1f895c6fe 30 (#) DAC channel1 with DAC_OUT1 (PA4) as output
mbed_official 340:28d1f895c6fe 31 (#) DAC channel2 with DAC_OUT2 (PA5) as output
mbed_official 340:28d1f895c6fe 32
mbed_official 340:28d1f895c6fe 33 *** DAC Triggers ***
mbed_official 340:28d1f895c6fe 34 ====================
mbed_official 340:28d1f895c6fe 35 [..]
mbed_official 630:825f75ca301e 36 Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
mbed_official 340:28d1f895c6fe 37 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
mbed_official 340:28d1f895c6fe 38 [..]
mbed_official 340:28d1f895c6fe 39 Digital to Analog conversion can be triggered by:
mbed_official 630:825f75ca301e 40 (#) External event: EXTI Line 9 (any GPIOx_PIN_9) using DAC_TRIGGER_EXT_IT9.
mbed_official 630:825f75ca301e 41 The used pin (GPIOx_PIN_9) must be configured in input mode.
mbed_official 340:28d1f895c6fe 42
mbed_official 340:28d1f895c6fe 43 (#) Timers TRGO: TIM2, TIM3, TIM6, and TIM15

mbed_official 340:28d1f895c6fe 48 *** DAC Buffer mode feature ***
mbed_official 340:28d1f895c6fe 49 ===============================
mbed_official 340:28d1f895c6fe 50 [..]
mbed_official 340:28d1f895c6fe 51 Each DAC channel integrates an output buffer that can be used to
mbed_official 340:28d1f895c6fe 52 reduce the output impedance, and to drive external loads directly
mbed_official 340:28d1f895c6fe 53 without having to add an external operational amplifier.
mbed_official 340:28d1f895c6fe 54 To enable, the output buffer use
mbed_official 630:825f75ca301e 55 sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
mbed_official 340:28d1f895c6fe 56 [..]
mbed_official 340:28d1f895c6fe 57 (@) Refer to the device datasheet for more details about output
mbed_official 340:28d1f895c6fe 58 impedance value with and without output buffer.
mbed_official 630:825f75ca301e 59
mbed_official 630:825f75ca301e 60 *** GPIO configurations guidelines ***
mbed_official 630:825f75ca301e 61 =====================
mbed_official 630:825f75ca301e 62 [..]
mbed_official 630:825f75ca301e 63 When a DAC channel is used (ex channel1 on PA4) and the other is not
mbed_official 630:825f75ca301e 64 (ex channel1 on PA5 is configured in Analog and disabled).
mbed_official 630:825f75ca301e 65 Channel1 may disturb channel2 as coupling effect.
mbed_official 630:825f75ca301e 66 Note that there is no coupling on channel2 as soon as channel2 is turned on.
mbed_official 630:825f75ca301e 67 Coupling on adjacent channel could be avoided as follows:
mbed_official 630:825f75ca301e 68 when unused PA5 is configured as INPUT PULL-UP or DOWN.
mbed_official 630:825f75ca301e 69 PA5 is configured in ANALOG just before it is turned on.
mbed_official 340:28d1f895c6fe 70
mbed_official 340:28d1f895c6fe 71 *** DAC wave generation feature ***
mbed_official 340:28d1f895c6fe 72 ===================================
mbed_official 340:28d1f895c6fe 73 [..]
mbed_official 340:28d1f895c6fe 74 Both DAC channels can be used to generate
mbed_official 340:28d1f895c6fe 75 (#) Noise wave
mbed_official 340:28d1f895c6fe 76 (#) Triangle wave
mbed_official 340:28d1f895c6fe 77
mbed_official 340:28d1f895c6fe 78 *** DAC data format ***
mbed_official 340:28d1f895c6fe 79 =======================
mbed_official 340:28d1f895c6fe 80 [..]
mbed_official 340:28d1f895c6fe 81 The DAC data format can be:
mbed_official 340:28d1f895c6fe 82 (#) 8-bit right alignment using DAC_ALIGN_8B_R
mbed_official 340:28d1f895c6fe 83 (#) 12-bit left alignment using DAC_ALIGN_12B_L
mbed_official 340:28d1f895c6fe 84 (#) 12-bit right alignment using DAC_ALIGN_12B_R
mbed_official 340:28d1f895c6fe 85
mbed_official 630:825f75ca301e 86 *** DAC data value to voltage correspondance ***
mbed_official 340:28d1f895c6fe 87 ================================================
mbed_official 340:28d1f895c6fe 88 [..]
mbed_official 340:28d1f895c6fe 89 The analog output voltage on each DAC channel pin is determined
mbed_official 340:28d1f895c6fe 90 by the following equation:
mbed_official 630:825f75ca301e 91 [..]
mbed_official 340:28d1f895c6fe 92 DAC_OUTx = VREF+ * DOR / 4095
mbed_official 630:825f75ca301e 93 (+) with DOR is the Data Output Register
mbed_official 630:825f75ca301e 94 [..]
mbed_official 340:28d1f895c6fe 95 VEF+ is the input voltage reference (refer to the device datasheet)
mbed_official 630:825f75ca301e 96 [..]
mbed_official 340:28d1f895c6fe 97 e.g. To set DAC_OUT1 to 0.7V, use
mbed_official 630:825f75ca301e 98 (+) Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V

mbed_official 340:28d1f895c6fe 100 *** DMA requests ***
mbed_official 340:28d1f895c6fe 101 =====================
mbed_official 340:28d1f895c6fe 102 [..]
mbed_official 340:28d1f895c6fe 103 A DMA1 request can be generated when an external trigger (but not
mbed_official 340:28d1f895c6fe 104 a software trigger) occurs if DMA1 requests are enabled using
mbed_official 340:28d1f895c6fe 105 HAL_DAC_Start_DMA()
mbed_official 340:28d1f895c6fe 106 [..]
mbed_official 340:28d1f895c6fe 107 DMA1 requests are mapped as following:
mbed_official 340:28d1f895c6fe 108 (#) DAC channel1 : mapped on DMA1 channel3 which must be
mbed_official 340:28d1f895c6fe 109 already configured
mbed_official 340:28d1f895c6fe 110 (#) DAC channel2 : mapped on DMA1 channel4 which must be
mbed_official 340:28d1f895c6fe 111 already configured
mbed_official 340:28d1f895c6fe 112
mbed_official 630:825f75ca301e 113 (@) For Dual mode and specific signal (Triangle and noise) generation please
mbed_official 630:825f75ca301e 114 refer to Extended Features Driver description
mbed_official 340:28d1f895c6fe 115 STM32F0 devices with one channel (one converting capability) does not
