mbed_official 330:c80ac197fa6a 19 ====================
mbed_official 330:c80ac197fa6a 20 [..]
mbed_official 330:c80ac197fa6a 21 The device integrates up to 3 12-bit Digital Analog Converters that can
mbed_official 330:c80ac197fa6a 22 be used independently or simultaneously (dual mode):
mbed_official 330:c80ac197fa6a 23 (#) DAC1 channel1 with DAC1_OUT1 (PA4) as output
mbed_official 330:c80ac197fa6a 24 (#) DAC1 channel2 with DAC1_OUT2 (PA5) as output

mbed_official 330:c80ac197fa6a 29 *** DAC Triggers ***
mbed_official 330:c80ac197fa6a 30 ====================
mbed_official 330:c80ac197fa6a 31 [..]
mbed_official 330:c80ac197fa6a 32 Digital to Analog conversion can be non-triggered using DAC_Trigger_None
mbed_official 330:c80ac197fa6a 33 and DAC1_OUT1/DAC1_OUT2/DAC2_OUT1 is available once writing to DHRx register.
mbed_official 330:c80ac197fa6a 34 [..]
mbed_official 330:c80ac197fa6a 35 Digital to Analog conversion can be triggered by:
mbed_official 330:c80ac197fa6a 36 (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
mbed_official 330:c80ac197fa6a 37 The used pin (GPIOx_Pin9) must be configured in input mode.

mbed_official 330:c80ac197fa6a 44 *** DAC Buffer mode feature ***
mbed_official 330:c80ac197fa6a 45 ===============================
mbed_official 330:c80ac197fa6a 46 [..]
mbed_official 330:c80ac197fa6a 47 Each DAC channel integrates an output buffer that can be used to
mbed_official 330:c80ac197fa6a 48 reduce the output impedance, and to drive external loads directly
mbed_official 330:c80ac197fa6a 49 without having to add an external operational amplifier.
mbed_official 330:c80ac197fa6a 50 To enable, the output buffer use
mbed_official 330:c80ac197fa6a 51 sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
mbed_official 330:c80ac197fa6a 52 [..]
mbed_official 330:c80ac197fa6a 53 (@) Refer to the device datasheet for more details about output
mbed_official 330:c80ac197fa6a 54 impedance value with and without output buffer.
mbed_official 330:c80ac197fa6a 55
mbed_official 330:c80ac197fa6a 56 *** DAC wave generation feature ***
mbed_official 330:c80ac197fa6a 57 ===================================
mbed_official 330:c80ac197fa6a 58 [..]
mbed_official 330:c80ac197fa6a 59 Both DAC channels of DAC1 can be used to generate
mbed_official 330:c80ac197fa6a 60 note that wave generation is not available in DAC2.
mbed_official 330:c80ac197fa6a 61 (#) Noise wave
mbed_official 330:c80ac197fa6a 62 (#) Triangle wave
mbed_official 330:c80ac197fa6a 63
mbed_official 330:c80ac197fa6a 64 Wave generation is NOT available in DAC2.
mbed_official 330:c80ac197fa6a 65
mbed_official 330:c80ac197fa6a 66 *** DAC data format ***
mbed_official 330:c80ac197fa6a 67 =======================
mbed_official 330:c80ac197fa6a 68 [..]
mbed_official 330:c80ac197fa6a 69 The DAC data format can be:
mbed_official 330:c80ac197fa6a 70 (#) 8-bit right alignment using DAC_ALIGN_8B_R
mbed_official 330:c80ac197fa6a 71 (#) 12-bit left alignment using DAC_ALIGN_12B_L
mbed_official 330:c80ac197fa6a 72 (#) 12-bit right alignment using DAC_ALIGN_12B_R
mbed_official 330:c80ac197fa6a 73
mbed_official 330:c80ac197fa6a 74 *** DAC data value to voltage correspondence ***
mbed_official 330:c80ac197fa6a 75 ================================================
mbed_official 330:c80ac197fa6a 76 [..]
mbed_official 330:c80ac197fa6a 77 The analog output voltage on each DAC channel pin is determined
mbed_official 330:c80ac197fa6a 78 by the following equation:
mbed_official 330:c80ac197fa6a 79 DAC_OUTx = VREF+ * DOR / 4095
mbed_official 330:c80ac197fa6a 80 with DOR is the Data Output Register
mbed_official 330:c80ac197fa6a 81 VEF+ is the input voltage reference (refer to the device datasheet)
mbed_official 330:c80ac197fa6a 82 e.g. To set DAC_OUT1 to 0.7V, use
mbed_official 330:c80ac197fa6a 83 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
mbed_official 330:c80ac197fa6a 84
mbed_official 330:c80ac197fa6a 85 *** DMA requests ***
mbed_official 330:c80ac197fa6a 86 =====================
mbed_official 330:c80ac197fa6a 87 [..]
mbed_official 330:c80ac197fa6a 88 A DMA1 or DMA2 request can be generated when an external trigger
mbed_official 330:c80ac197fa6a 89 (but not a software trigger) occurs if DMA1 or DMA2 requests are
mbed_official 330:c80ac197fa6a 90 enabled using HAL_DAC_Start_DMA()
mbed_official 330:c80ac197fa6a 91 [..]
mbed_official 330:c80ac197fa6a 92 DMA1 requests are mapped as following:

mbed_official 330:c80ac197fa6a 94 - DMA1 channel3
mbed_official 330:c80ac197fa6a 95 - or DMA2 channel3 (for STM32F3 devices having 2 DMA)
mbed_official 330:c80ac197fa6a 96 which must be already configured
