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 | 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 |
