ganlikun 0:13413ea9a877 17 ==============================================================================
ganlikun 0:13413ea9a877 18 ##### DAC Peripheral features #####
ganlikun 0:13413ea9a877 19 ==============================================================================
ganlikun 0:13413ea9a877 20 [..]
ganlikun 0:13413ea9a877 21 *** DAC Channels ***
ganlikun 0:13413ea9a877 22 ====================
ganlikun 0:13413ea9a877 23 [..]
ganlikun 0:13413ea9a877 24 The device integrates two 12-bit Digital Analog Converters that can
ganlikun 0:13413ea9a877 25 be used independently or simultaneously (dual mode):
ganlikun 0:13413ea9a877 26 (#) DAC channel1 with DAC_OUT1 (PA4) as output
ganlikun 0:13413ea9a877 27 (#) DAC channel2 with DAC_OUT2 (PA5) as output
ganlikun 0:13413ea9a877 28
ganlikun 0:13413ea9a877 29 *** DAC Triggers ***
ganlikun 0:13413ea9a877 30 ====================
ganlikun 0:13413ea9a877 31 [..]
ganlikun 0:13413ea9a877 32 Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
ganlikun 0:13413ea9a877 33 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
ganlikun 0:13413ea9a877 34 [..]
ganlikun 0:13413ea9a877 35 Digital to Analog conversion can be triggered by:
ganlikun 0:13413ea9a877 36 (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_TRIGGER_EXT_IT9.
ganlikun 0:13413ea9a877 37 The used pin (GPIOx_Pin9) must be configured in input mode.
ganlikun 0:13413ea9a877 38
ganlikun 0:13413ea9a877 39 (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8
ganlikun 0:13413ea9a877 40 (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T4_TRGO...)
ganlikun 0:13413ea9a877 41
ganlikun 0:13413ea9a877 42 (#) Software using DAC_TRIGGER_SOFTWARE
ganlikun 0:13413ea9a877 43
ganlikun 0:13413ea9a877 44 *** DAC Buffer mode feature ***
ganlikun 0:13413ea9a877 45 ===============================
ganlikun 0:13413ea9a877 46 [..]
ganlikun 0:13413ea9a877 47 Each DAC channel integrates an output buffer that can be used to
ganlikun 0:13413ea9a877 48 reduce the output impedance, and to drive external loads directly
ganlikun 0:13413ea9a877 49 without having to add an external operational amplifier.
ganlikun 0:13413ea9a877 50 To enable, the output buffer use
ganlikun 0:13413ea9a877 51 sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
ganlikun 0:13413ea9a877 52 [..]
ganlikun 0:13413ea9a877 53 (@) Refer to the device datasheet for more details about output
ganlikun 0:13413ea9a877 54 impedance value with and without output buffer.
ganlikun 0:13413ea9a877 55
ganlikun 0:13413ea9a877 56 *** DAC wave generation feature ***
ganlikun 0:13413ea9a877 57 ===================================
ganlikun 0:13413ea9a877 58 [..]
ganlikun 0:13413ea9a877 59 Both DAC channels can be used to generate
ganlikun 0:13413ea9a877 60 (#) Noise wave
ganlikun 0:13413ea9a877 61 (#) Triangle wave
ganlikun 0:13413ea9a877 62
ganlikun 0:13413ea9a877 63 *** DAC data format ***
ganlikun 0:13413ea9a877 64 =======================
ganlikun 0:13413ea9a877 65 [..]
ganlikun 0:13413ea9a877 66 The DAC data format can be:
ganlikun 0:13413ea9a877 67 (#) 8-bit right alignment using DAC_ALIGN_8B_R
ganlikun 0:13413ea9a877 68 (#) 12-bit left alignment using DAC_ALIGN_12B_L
ganlikun 0:13413ea9a877 69 (#) 12-bit right alignment using DAC_ALIGN_12B_R
ganlikun 0:13413ea9a877 70
ganlikun 0:13413ea9a877 71 *** DAC data value to voltage correspondence ***
ganlikun 0:13413ea9a877 72 ================================================
ganlikun 0:13413ea9a877 73 [..]
ganlikun 0:13413ea9a877 74 The analog output voltage on each DAC channel pin is determined
ganlikun 0:13413ea9a877 75 by the following equation:
ganlikun 0:13413ea9a877 76 DAC_OUTx = VREF+ * DOR / 4095
ganlikun 0:13413ea9a877 77 with DOR is the Data Output Register
ganlikun 0:13413ea9a877 78 VEF+ is the input voltage reference (refer to the device datasheet)
ganlikun 0:13413ea9a877 79 e.g. To set DAC_OUT1 to 0.7V, use
ganlikun 0:13413ea9a877 80 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
ganlikun 0:13413ea9a877 81
ganlikun 0:13413ea9a877 82 *** DMA requests ***
ganlikun 0:13413ea9a877 83 =====================
ganlikun 0:13413ea9a877 84 [..]
ganlikun 0:13413ea9a877 85 A DMA1 request can be generated when an external trigger (but not
ganlikun 0:13413ea9a877 86 a software trigger) occurs if DMA1 requests are enabled using
ganlikun 0:13413ea9a877 87 HAL_DAC_Start_DMA()
ganlikun 0:13413ea9a877 88 [..]
ganlikun 0:13413ea9a877 89 DMA1 requests are mapped as following:
ganlikun 0:13413ea9a877 90 (#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be
ganlikun 0:13413ea9a877 91 already configured
ganlikun 0:13413ea9a877 92 (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be
ganlikun 0:13413ea9a877 93 already configured
ganlikun 0:13413ea9a877 94
ganlikun 0:13413ea9a877 95 -@- For Dual mode and specific signal (Triangle and noise) generation please
ganlikun 0:13413ea9a877 96 refer to Extension Features Driver description
