mbed_official 237:f3da66175598 19 ====================
mbed_official 237:f3da66175598 20 [..]
mbed_official 237:f3da66175598 21 The device integrates up to 3 12-bit Digital Analog Converters that can
mbed_official 237:f3da66175598 22 be used independently or simultaneously (dual mode):

mbed_official 237:f3da66175598 30 ====================
mbed_official 237:f3da66175598 31 [..]
mbed_official 237:f3da66175598 32 Digital to Analog conversion can be non-triggered using DAC_Trigger_None
mbed_official 237:f3da66175598 33 and DAC1_OUT1/DAC1_OUT2/DAC2_OUT1 is available once writing to DHRx register.
mbed_official 237:f3da66175598 34 [..]
mbed_official 237:f3da66175598 35 Digital to Analog conversion can be triggered by:
mbed_official 237:f3da66175598 36 (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
mbed_official 237:f3da66175598 37 The used pin (GPIOx_Pin9) must be configured in input mode.

mbed_official 237:f3da66175598 45 ===============================
mbed_official 237:f3da66175598 46 [..]
mbed_official 237:f3da66175598 47 Each DAC channel integrates an output buffer that can be used to
mbed_official 237:f3da66175598 48 reduce the output impedance, and to drive external loads directly
mbed_official 237:f3da66175598 49 without having to add an external operational amplifier.
mbed_official 237:f3da66175598 50 To enable, the output buffer use
mbed_official 237:f3da66175598 51 sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
mbed_official 237:f3da66175598 52 [..]
mbed_official 237:f3da66175598 53 (@) Refer to the device datasheet for more details about output
mbed_official 237:f3da66175598 54 impedance value with and without output buffer.

mbed_official 237:f3da66175598 56 *** DAC wave generation feature ***
mbed_official 237:f3da66175598 57 ===================================
mbed_official 237:f3da66175598 58 [..]
mbed_official 237:f3da66175598 59 Both DAC channels of DAC1 can be used to generate
mbed_official 237:f3da66175598 60 note that wave generation is not available in DAC2.

mbed_official 237:f3da66175598 64 Wave generation is NOT available in DAC2.
mbed_official 237:f3da66175598 65
mbed_official 237:f3da66175598 66 *** DAC data format ***
mbed_official 237:f3da66175598 67 =======================
mbed_official 237:f3da66175598 68 [..]
mbed_official 237:f3da66175598 69 The DAC data format can be:
mbed_official 237:f3da66175598 70 (#) 8-bit right alignment using DAC_ALIGN_8B_R
mbed_official 237:f3da66175598 71 (#) 12-bit left alignment using DAC_ALIGN_12B_L
mbed_official 237:f3da66175598 72 (#) 12-bit right alignment using DAC_ALIGN_12B_R
mbed_official 237:f3da66175598 73
mbed_official 237:f3da66175598 74 *** DAC data value to voltage correspondence ***
mbed_official 237:f3da66175598 75 ================================================
mbed_official 237:f3da66175598 76 [..]
mbed_official 237:f3da66175598 77 The analog output voltage on each DAC channel pin is determined
mbed_official 237:f3da66175598 78 by the following equation:
mbed_official 237:f3da66175598 79 DAC_OUTx = VREF+ * DOR / 4095
mbed_official 237:f3da66175598 80 with DOR is the Data Output Register
mbed_official 237:f3da66175598 81 VEF+ is the input voltage reference (refer to the device datasheet)
mbed_official 237:f3da66175598 82 e.g. To set DAC_OUT1 to 0.7V, use
mbed_official 237:f3da66175598 83 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
mbed_official 237:f3da66175598 84
mbed_official 237:f3da66175598 85 *** DMA requests ***
mbed_official 237:f3da66175598 86 =====================
mbed_official 237:f3da66175598 87 [..]
mbed_official 237:f3da66175598 88 A DMA1 or DMA2 request can be generated when an external trigger
mbed_official 237:f3da66175598 89 (but not a software trigger) occurs if DMA1 or DMA2 requests are
mbed_official 237:f3da66175598 90 enabled using HAL_DAC_Start_DMA()
mbed_official 237:f3da66175598 91 [..]
mbed_official 237:f3da66175598 92 DMA1 requests are mapped as following:
