mbed_official 133:d4dda5c437f0 18 ##### DAC Peripheral features #####
mbed_official 133:d4dda5c437f0 19 ==============================================================================
mbed_official 133:d4dda5c437f0 20 [..]
mbed_official 133:d4dda5c437f0 21 *** DAC Channels ***
mbed_official 133:d4dda5c437f0 22 ====================
mbed_official 133:d4dda5c437f0 23 [..]
mbed_official 133:d4dda5c437f0 24 The device integrates two 12-bit Digital Analog Converters that can
mbed_official 133:d4dda5c437f0 25 be used independently or simultaneously (dual mode):
mbed_official 133:d4dda5c437f0 26 (#) DAC channel1 with DAC_OUT1 (PA4) as output
mbed_official 133:d4dda5c437f0 27 (#) DAC channel2 with DAC_OUT2 (PA5) as output
mbed_official 133:d4dda5c437f0 28
mbed_official 133:d4dda5c437f0 29 *** DAC Triggers ***
mbed_official 133:d4dda5c437f0 30 ====================
mbed_official 133:d4dda5c437f0 31 [..]
mbed_official 133:d4dda5c437f0 32 Digital to Analog conversion can be non-triggered using DAC_Trigger_None
mbed_official 133:d4dda5c437f0 33 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
mbed_official 133:d4dda5c437f0 34 [..]
mbed_official 133:d4dda5c437f0 35 Digital to Analog conversion can be triggered by:
mbed_official 133:d4dda5c437f0 36 (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
mbed_official 133:d4dda5c437f0 37 The used pin (GPIOx_Pin9) must be configured in input mode.
mbed_official 133:d4dda5c437f0 38
mbed_official 133:d4dda5c437f0 39 (#) Timers TRGO: TIM2, TIM4, TIM5, TIM6, TIM7 and TIM8
mbed_official 133:d4dda5c437f0 40 (DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...)
mbed_official 133:d4dda5c437f0 41
mbed_official 133:d4dda5c437f0 42 (#) Software using DAC_Trigger_Software
mbed_official 133:d4dda5c437f0 43
mbed_official 133:d4dda5c437f0 44 *** DAC Buffer mode feature ***
mbed_official 133:d4dda5c437f0 45 ===============================
mbed_official 133:d4dda5c437f0 46 [..]
mbed_official 133:d4dda5c437f0 47 Each DAC channel integrates an output buffer that can be used to
mbed_official 133:d4dda5c437f0 48 reduce the output impedance, and to drive external loads directly
mbed_official 133:d4dda5c437f0 49 without having to add an external operational amplifier.
mbed_official 133:d4dda5c437f0 50 To enable, the output buffer use
mbed_official 133:d4dda5c437f0 51 sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
mbed_official 133:d4dda5c437f0 52 [..]
mbed_official 133:d4dda5c437f0 53 (@) Refer to the device datasheet for more details about output
mbed_official 133:d4dda5c437f0 54 impedance value with and without output buffer.
mbed_official 133:d4dda5c437f0 55
mbed_official 133:d4dda5c437f0 56 *** DAC wave generation feature ***
mbed_official 133:d4dda5c437f0 57 ===================================
mbed_official 133:d4dda5c437f0 58 [..]
mbed_official 133:d4dda5c437f0 59 Both DAC channels can be used to generate
mbed_official 133:d4dda5c437f0 60 (#) Noise wave
mbed_official 133:d4dda5c437f0 61 (#) Triangle wave
mbed_official 133:d4dda5c437f0 62
mbed_official 133:d4dda5c437f0 63 *** DAC data format ***
mbed_official 133:d4dda5c437f0 64 =======================
mbed_official 133:d4dda5c437f0 65 [..]
mbed_official 133:d4dda5c437f0 66 The DAC data format can be:
mbed_official 133:d4dda5c437f0 67 (#) 8-bit right alignment using DAC_ALIGN_8B_R
mbed_official 133:d4dda5c437f0 68 (#) 12-bit left alignment using DAC_ALIGN_12B_L
mbed_official 133:d4dda5c437f0 69 (#) 12-bit right alignment using DAC_ALIGN_12B_R
mbed_official 133:d4dda5c437f0 70
mbed_official 133:d4dda5c437f0 71 *** DAC data value to voltage correspondence ***
mbed_official 133:d4dda5c437f0 72 ================================================
mbed_official 133:d4dda5c437f0 73 [..]
mbed_official 133:d4dda5c437f0 74 The analog output voltage on each DAC channel pin is determined
mbed_official 133:d4dda5c437f0 75 by the following equation:
mbed_official 133:d4dda5c437f0 76 DAC_OUTx = VREF+ * DOR / 4095
mbed_official 133:d4dda5c437f0 77 with DOR is the Data Output Register
mbed_official 133:d4dda5c437f0 78 VEF+ is the input voltage reference (refer to the device datasheet)
mbed_official 133:d4dda5c437f0 79 e.g. To set DAC_OUT1 to 0.7V, use
mbed_official 133:d4dda5c437f0 80 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
mbed_official 133:d4dda5c437f0 81
mbed_official 133:d4dda5c437f0 82 *** DMA requests ***
mbed_official 133:d4dda5c437f0 83 =====================
mbed_official 133:d4dda5c437f0 84 [..]
mbed_official 133:d4dda5c437f0 85 A DMA1 request can be generated when an external trigger (but not
mbed_official 133:d4dda5c437f0 86 a software trigger) occurs if DMA1 requests are enabled using
mbed_official 133:d4dda5c437f0 87 HAL_DAC_Start_DMA()
mbed_official 133:d4dda5c437f0 88 [..]
mbed_official 133:d4dda5c437f0 89 DMA1 requests are mapped as following:
mbed_official 133:d4dda5c437f0 90 (#) DAC channel1 : mapped on DMA1 Stream5 channel7 which must be
mbed_official 133:d4dda5c437f0 91 already configured
mbed_official 133:d4dda5c437f0 92 (#) DAC channel2 : mapped on DMA1 Stream6 channel7 which must be
mbed_official 133:d4dda5c437f0 93 already configured
mbed_official 133:d4dda5c437f0 94
mbed_official 133:d4dda5c437f0 95 -@- For Dual mode and specific signal (Triangle and noise) generation please
