mbed_official 205:c41fc65bcfb4 18 ##### DAC Peripheral features #####
mbed_official 205:c41fc65bcfb4 19 ==============================================================================
mbed_official 205:c41fc65bcfb4 20 [..]
mbed_official 205:c41fc65bcfb4 21 *** DAC Channels ***
mbed_official 205:c41fc65bcfb4 22 ====================
mbed_official 205:c41fc65bcfb4 23 [..]
mbed_official 205:c41fc65bcfb4 24 STM32F0 devices integrates no, one or two 12-bit Digital Analog Converters.
mbed_official 205:c41fc65bcfb4 25 STM32F05x devices have one converter (channel1)
mbed_official 205:c41fc65bcfb4 26 STM32F07x & STM32F09x devices have two converters (i.e. channel1 & channel2)
mbed_official 205:c41fc65bcfb4 27
mbed_official 205:c41fc65bcfb4 28 When 2 converters are present (i.e. channel1 & channel2) they
mbed_official 205:c41fc65bcfb4 29 can be used independently or simultaneously (dual mode):
mbed_official 205:c41fc65bcfb4 30 (#) DAC channel1 with DAC_OUT1 (PA4) as output
mbed_official 205:c41fc65bcfb4 31 (#) DAC channel2 with DAC_OUT2 (PA5) as output
mbed_official 205:c41fc65bcfb4 32
mbed_official 205:c41fc65bcfb4 33 *** DAC Triggers ***
mbed_official 205:c41fc65bcfb4 34 ====================
mbed_official 205:c41fc65bcfb4 35 [..]
mbed_official 205:c41fc65bcfb4 36 Digital to Analog conversion can be non-triggered using DAC_Trigger_None
mbed_official 205:c41fc65bcfb4 37 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
mbed_official 205:c41fc65bcfb4 38 [..]
mbed_official 205:c41fc65bcfb4 39 Digital to Analog conversion can be triggered by:
mbed_official 205:c41fc65bcfb4 40 (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
mbed_official 205:c41fc65bcfb4 41 The used pin (GPIOx_Pin9) must be configured in input mode.
mbed_official 205:c41fc65bcfb4 42
mbed_official 205:c41fc65bcfb4 43 (#) Timers TRGO: TIM2, TIM3, TIM6, and TIM15
mbed_official 205:c41fc65bcfb4 44 (DAC_Trigger_T2_TRGO, DAC_Trigger_T3_TRGO...)
mbed_official 205:c41fc65bcfb4 45
mbed_official 205:c41fc65bcfb4 46 (#) Software using DAC_Trigger_Software
mbed_official 205:c41fc65bcfb4 47
mbed_official 205:c41fc65bcfb4 48 *** DAC Buffer mode feature ***
mbed_official 205:c41fc65bcfb4 49 ===============================
mbed_official 205:c41fc65bcfb4 50 [..]
mbed_official 205:c41fc65bcfb4 51 Each DAC channel integrates an output buffer that can be used to
mbed_official 205:c41fc65bcfb4 52 reduce the output impedance, and to drive external loads directly
mbed_official 205:c41fc65bcfb4 53 without having to add an external operational amplifier.
mbed_official 205:c41fc65bcfb4 54 To enable, the output buffer use
mbed_official 205:c41fc65bcfb4 55 sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
mbed_official 205:c41fc65bcfb4 56 [..]
mbed_official 205:c41fc65bcfb4 57 (@) Refer to the device datasheet for more details about output
mbed_official 205:c41fc65bcfb4 58 impedance value with and without output buffer.
mbed_official 205:c41fc65bcfb4 59
mbed_official 205:c41fc65bcfb4 60 *** DAC wave generation feature ***
mbed_official 205:c41fc65bcfb4 61 ===================================
mbed_official 205:c41fc65bcfb4 62 [..]
mbed_official 205:c41fc65bcfb4 63 Both DAC channels can be used to generate
mbed_official 205:c41fc65bcfb4 64 (#) Noise wave
mbed_official 205:c41fc65bcfb4 65 (#) Triangle wave
mbed_official 205:c41fc65bcfb4 66
mbed_official 205:c41fc65bcfb4 67 *** DAC data format ***
mbed_official 205:c41fc65bcfb4 68 =======================
mbed_official 205:c41fc65bcfb4 69 [..]
mbed_official 205:c41fc65bcfb4 70 The DAC data format can be:
mbed_official 205:c41fc65bcfb4 71 (#) 8-bit right alignment using DAC_ALIGN_8B_R
mbed_official 205:c41fc65bcfb4 72 (#) 12-bit left alignment using DAC_ALIGN_12B_L
mbed_official 205:c41fc65bcfb4 73 (#) 12-bit right alignment using DAC_ALIGN_12B_R
mbed_official 205:c41fc65bcfb4 74
mbed_official 205:c41fc65bcfb4 75 *** DAC data value to voltage correspondence ***
mbed_official 205:c41fc65bcfb4 76 ================================================
mbed_official 205:c41fc65bcfb4 77 [..]
mbed_official 205:c41fc65bcfb4 78 The analog output voltage on each DAC channel pin is determined
mbed_official 205:c41fc65bcfb4 79 by the following equation:
mbed_official 205:c41fc65bcfb4 80 DAC_OUTx = VREF+ * DOR / 4095
mbed_official 205:c41fc65bcfb4 81 with DOR is the Data Output Register
mbed_official 205:c41fc65bcfb4 82 VEF+ is the input voltage reference (refer to the device datasheet)
mbed_official 205:c41fc65bcfb4 83 e.g. To set DAC_OUT1 to 0.7V, use
mbed_official 205:c41fc65bcfb4 84 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
mbed_official 205:c41fc65bcfb4 85
mbed_official 205:c41fc65bcfb4 86 *** DMA requests ***
mbed_official 205:c41fc65bcfb4 87 =====================
mbed_official 205:c41fc65bcfb4 88 [..]
mbed_official 205:c41fc65bcfb4 89 A DMA1 request can be generated when an external trigger (but not
mbed_official 205:c41fc65bcfb4 90 a software trigger) occurs if DMA1 requests are enabled using
mbed_official 205:c41fc65bcfb4 91 HAL_DAC_Start_DMA()
mbed_official 205:c41fc65bcfb4 92 [..]
mbed_official 205:c41fc65bcfb4 93 DMA1 requests are mapped as following:
mbed_official 205:c41fc65bcfb4 94 (#) DAC channel1 : mapped on DMA1 channel3 which must be
mbed_official 205:c41fc65bcfb4 95 already configured
mbed_official 205:c41fc65bcfb4 96 (#) DAC channel2 : mapped on DMA1 channel4 which must be
mbed_official 205:c41fc65bcfb4 97 already configured
mbed_official 205:c41fc65bcfb4 98
mbed_official 205:c41fc65bcfb4 99 -@- For Dual mode and specific signal (Triangle and noise) generation please
mbed_official 205:c41fc65bcfb4 100 refer to Extension Features Driver description
mbed_official 205:c41fc65bcfb4 101 STM32F0 devices with one channel (one converting capability) does not
mbed_official 205:c41fc65bcfb4 102 support Dual mode and specific signal (Triangle and noise) generation.
