<> 144:ef7eb2e8f9f7 32 ====================
<> 144:ef7eb2e8f9f7 33 [..]
<> 144:ef7eb2e8f9f7 34 Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
<> 144:ef7eb2e8f9f7 35 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.

<> 144:ef7eb2e8f9f7 47 ===============================
<> 144:ef7eb2e8f9f7 48 [..]
<> 144:ef7eb2e8f9f7 49 Each DAC channel integrates an output buffer that can be used to
<> 144:ef7eb2e8f9f7 50 reduce the output impedance, and to drive external loads directly
<> 144:ef7eb2e8f9f7 51 without having to add an external operational amplifier.
<> 144:ef7eb2e8f9f7 52 To enable, the output buffer use
<> 144:ef7eb2e8f9f7 53 sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
<> 144:ef7eb2e8f9f7 54 [..]
<> 144:ef7eb2e8f9f7 55 (@) Refer to the device datasheet for more details about output

<> 144:ef7eb2e8f9f7 58 *** GPIO configurations guidelines ***
<> 144:ef7eb2e8f9f7 59 =====================
<> 144:ef7eb2e8f9f7 60 [..]
<> 144:ef7eb2e8f9f7 61 When a DAC channel is used (ex channel1 on PA4) and the other is not
<> 144:ef7eb2e8f9f7 62 (ex channel1 on PA5 is configured in Analog and disabled).
<> 144:ef7eb2e8f9f7 63 Channel1 may disturb channel2 as coupling effect.
<> 144:ef7eb2e8f9f7 64 Note that there is no coupling on channel2 as soon as channel2 is turned on.
<> 144:ef7eb2e8f9f7 65 Coupling on adjacent channel could be avoided as follows:
<> 144:ef7eb2e8f9f7 66 when unused PA5 is configured as INPUT PULL-UP or DOWN.
<> 144:ef7eb2e8f9f7 67 PA5 is configured in ANALOG just before it is turned on.
<> 144:ef7eb2e8f9f7 68
<> 144:ef7eb2e8f9f7 69 *** DAC wave generation feature ***
<> 144:ef7eb2e8f9f7 70 ===================================
<> 144:ef7eb2e8f9f7 71 [..]

<> 144:ef7eb2e8f9f7 84 *** DAC data value to voltage correspondance ***
<> 144:ef7eb2e8f9f7 85 ================================================
<> 144:ef7eb2e8f9f7 86 [..]
<> 144:ef7eb2e8f9f7 87 The analog output voltage on each DAC channel pin is determined

<> 144:ef7eb2e8f9f7 89 [..]
<> 144:ef7eb2e8f9f7 90 DAC_OUTx = VREF+ * DOR / 4095

<> 144:ef7eb2e8f9f7 94 [..]
<> 144:ef7eb2e8f9f7 95 e.g. To set DAC_OUT1 to 0.7V, use
<> 144:ef7eb2e8f9f7 96 (+) Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V

<> 144:ef7eb2e8f9f7 98 *** DMA requests ***
<> 144:ef7eb2e8f9f7 99 =====================
<> 144:ef7eb2e8f9f7 100 [..]
<> 144:ef7eb2e8f9f7 101 A DMA1 request can be generated when an external trigger (but not
<> 144:ef7eb2e8f9f7 102 a software trigger) occurs if DMA1 requests are enabled using

<> 144:ef7eb2e8f9f7 104 [..]
<> 144:ef7eb2e8f9f7 105 DMA1 requests are mapped as following:

<> 144:ef7eb2e8f9f7 108 (#) DAC channel2 : mapped on DMA1 channel4 which must be
<> 144:ef7eb2e8f9f7 109 already configured
<> 144:ef7eb2e8f9f7 110
<> 144:ef7eb2e8f9f7 111 (@) For Dual mode and specific signal (Triangle and noise) generation please
<> 144:ef7eb2e8f9f7 112 refer to Extended Features Driver description
<> 144:ef7eb2e8f9f7 113 STM32F0 devices with one channel (one converting capability) does not
