<> 144:ef7eb2e8f9f7 35 [..]
<> 144:ef7eb2e8f9f7 36 Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
<> 144:ef7eb2e8f9f7 37 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.

<> 144:ef7eb2e8f9f7 49 ===============================
<> 144:ef7eb2e8f9f7 50 [..]
<> 144:ef7eb2e8f9f7 51 Each DAC channel integrates an output buffer that can be used to
<> 144:ef7eb2e8f9f7 52 reduce the output impedance, and to drive external loads directly
<> 144:ef7eb2e8f9f7 53 without having to add an external operational amplifier.
<> 144:ef7eb2e8f9f7 54 To enable, the output buffer use
<> 144:ef7eb2e8f9f7 55 sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
<> 144:ef7eb2e8f9f7 56 [..]
<> 144:ef7eb2e8f9f7 57 (@) Refer to the device datasheet for more details about output
<> 144:ef7eb2e8f9f7 58 impedance value with and without output buffer.
<> 144:ef7eb2e8f9f7 59
<> 144:ef7eb2e8f9f7 60 *** GPIO configurations guidelines ***
<> 144:ef7eb2e8f9f7 61 =====================
<> 144:ef7eb2e8f9f7 62 [..]
<> 144:ef7eb2e8f9f7 63 When a DAC channel is used (ex channel1 on PA4) and the other is not
<> 144:ef7eb2e8f9f7 64 (ex channel1 on PA5 is configured in Analog and disabled).
<> 144:ef7eb2e8f9f7 65 Channel1 may disturb channel2 as coupling effect.
<> 144:ef7eb2e8f9f7 66 Note that there is no coupling on channel2 as soon as channel2 is turned on.
<> 144:ef7eb2e8f9f7 67 Coupling on adjacent channel could be avoided as follows:
<> 144:ef7eb2e8f9f7 68 when unused PA5 is configured as INPUT PULL-UP or DOWN.
<> 144:ef7eb2e8f9f7 69 PA5 is configured in ANALOG just before it is turned on.
<> 144:ef7eb2e8f9f7 70
<> 144:ef7eb2e8f9f7 71 *** DAC wave generation feature ***
<> 144:ef7eb2e8f9f7 72 ===================================
<> 144:ef7eb2e8f9f7 73 [..]

<> 144:ef7eb2e8f9f7 86 *** DAC data value to voltage correspondance ***
<> 144:ef7eb2e8f9f7 87 ================================================
<> 144:ef7eb2e8f9f7 88 [..]
<> 144:ef7eb2e8f9f7 89 The analog output voltage on each DAC channel pin is determined
<> 144:ef7eb2e8f9f7 90 by the following equation:
<> 144:ef7eb2e8f9f7 91 [..]
<> 144:ef7eb2e8f9f7 92 DAC_OUTx = VREF+ * DOR / 4095

<> 144:ef7eb2e8f9f7 96 [..]
<> 144:ef7eb2e8f9f7 97 e.g. To set DAC_OUT1 to 0.7V, use
<> 144:ef7eb2e8f9f7 98 (+) Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V

<> 144:ef7eb2e8f9f7 100 *** DMA requests ***
<> 144:ef7eb2e8f9f7 101 =====================
<> 144:ef7eb2e8f9f7 102 [..]
<> 144:ef7eb2e8f9f7 103 A DMA1 request can be generated when an external trigger (but not
<> 144:ef7eb2e8f9f7 104 a software trigger) occurs if DMA1 requests are enabled using

<> 144:ef7eb2e8f9f7 106 [..]

<> 144:ef7eb2e8f9f7 110 (#) DAC channel2 : mapped on DMA1 channel4 which must be
<> 144:ef7eb2e8f9f7 111 already configured
<> 144:ef7eb2e8f9f7 112
<> 144:ef7eb2e8f9f7 113 (@) For Dual mode and specific signal (Triangle and noise) generation please
