lypinator 0:bb348c97df44 16 ##### DAC Peripheral features #####
lypinator 0:bb348c97df44 17 ==============================================================================
lypinator 0:bb348c97df44 18 [..]
lypinator 0:bb348c97df44 19 *** DAC Channels ***
lypinator 0:bb348c97df44 20 ====================
lypinator 0:bb348c97df44 21 [..]
lypinator 0:bb348c97df44 22 The device integrates two 12-bit Digital Analog Converters that can
lypinator 0:bb348c97df44 23 be used independently or simultaneously (dual mode):
lypinator 0:bb348c97df44 24 (#) DAC channel1 with DAC_OUT1 (PA4) as output
lypinator 0:bb348c97df44 25 (#) DAC channel2 with DAC_OUT2 (PA5) as output
lypinator 0:bb348c97df44 26
lypinator 0:bb348c97df44 27 *** DAC Triggers ***
lypinator 0:bb348c97df44 28 ====================
lypinator 0:bb348c97df44 29 [..]
lypinator 0:bb348c97df44 30 Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE
lypinator 0:bb348c97df44 31 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
lypinator 0:bb348c97df44 32 [..]
lypinator 0:bb348c97df44 33 Digital to Analog conversion can be triggered by:
lypinator 0:bb348c97df44 34 (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_TRIGGER_EXT_IT9.
lypinator 0:bb348c97df44 35 The used pin (GPIOx_Pin9) must be configured in input mode.
lypinator 0:bb348c97df44 36
lypinator 0:bb348c97df44 37 (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8
lypinator 0:bb348c97df44 38 (DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T4_TRGO...)
lypinator 0:bb348c97df44 39
lypinator 0:bb348c97df44 40 (#) Software using DAC_TRIGGER_SOFTWARE
lypinator 0:bb348c97df44 41
lypinator 0:bb348c97df44 42 *** DAC Buffer mode feature ***
lypinator 0:bb348c97df44 43 ===============================
lypinator 0:bb348c97df44 44 [..]
lypinator 0:bb348c97df44 45 Each DAC channel integrates an output buffer that can be used to
lypinator 0:bb348c97df44 46 reduce the output impedance, and to drive external loads directly
lypinator 0:bb348c97df44 47 without having to add an external operational amplifier.
lypinator 0:bb348c97df44 48 To enable, the output buffer use
lypinator 0:bb348c97df44 49 sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE;
lypinator 0:bb348c97df44 50 [..]
lypinator 0:bb348c97df44 51 (@) Refer to the device datasheet for more details about output
lypinator 0:bb348c97df44 52 impedance value with and without output buffer.
lypinator 0:bb348c97df44 53
lypinator 0:bb348c97df44 54 *** DAC wave generation feature ***
lypinator 0:bb348c97df44 55 ===================================
lypinator 0:bb348c97df44 56 [..]
lypinator 0:bb348c97df44 57 Both DAC channels can be used to generate
lypinator 0:bb348c97df44 58 (#) Noise wave
lypinator 0:bb348c97df44 59 (#) Triangle wave
lypinator 0:bb348c97df44 60
lypinator 0:bb348c97df44 61 *** DAC data format ***
lypinator 0:bb348c97df44 62 =======================
lypinator 0:bb348c97df44 63 [..]
lypinator 0:bb348c97df44 64 The DAC data format can be:
lypinator 0:bb348c97df44 65 (#) 8-bit right alignment using DAC_ALIGN_8B_R
lypinator 0:bb348c97df44 66 (#) 12-bit left alignment using DAC_ALIGN_12B_L
lypinator 0:bb348c97df44 67 (#) 12-bit right alignment using DAC_ALIGN_12B_R
lypinator 0:bb348c97df44 68
lypinator 0:bb348c97df44 69 *** DAC data value to voltage correspondence ***
lypinator 0:bb348c97df44 70 ================================================
lypinator 0:bb348c97df44 71 [..]
lypinator 0:bb348c97df44 72 The analog output voltage on each DAC channel pin is determined
lypinator 0:bb348c97df44 73 by the following equation:
lypinator 0:bb348c97df44 74 DAC_OUTx = VREF+ * DOR / 4095
lypinator 0:bb348c97df44 75 with DOR is the Data Output Register
lypinator 0:bb348c97df44 76 VEF+ is the input voltage reference (refer to the device datasheet)
lypinator 0:bb348c97df44 77 e.g. To set DAC_OUT1 to 0.7V, use
lypinator 0:bb348c97df44 78 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
lypinator 0:bb348c97df44 79
lypinator 0:bb348c97df44 80 *** DMA requests ***
lypinator 0:bb348c97df44 81 =====================
lypinator 0:bb348c97df44 82 [..]
lypinator 0:bb348c97df44 83 A DMA1 request can be generated when an external trigger (but not
lypinator 0:bb348c97df44 84 a software trigger) occurs if DMA1 requests are enabled using
lypinator 0:bb348c97df44 85 HAL_DAC_Start_DMA()
lypinator 0:bb348c97df44 86 [..]
lypinator 0:bb348c97df44 87 DMA1 requests are mapped as following:
lypinator 0:bb348c97df44 88 (#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be
lypinator 0:bb348c97df44 89 already configured
lypinator 0:bb348c97df44 90 (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be
lypinator 0:bb348c97df44 91 already configured
lypinator 0:bb348c97df44 92
lypinator 0:bb348c97df44 93 -@- For Dual mode and specific signal (Triangle and noise) generation please
lypinator 0:bb348c97df44 94 refer to Extension Features Driver description

lypinator 0:bb348c97df44 119 function is executed and user can add his own code by customization of function pointer
lypinator 0:bb348c97df44 120 HAL_DAC_ConvCpltCallbackCh1 or HAL_DAC_ConvCpltCallbackCh2
lypinator 0:bb348c97df44 121 (+) In case of transfer Error, HAL_DAC_ErrorCallbackCh1() function is executed and user can
