Revision:
70:b3a5af880266
Parent:
0:9b334a45a8ff 
Edited DAC routines to allow for the simultaneous use of three channels from two DACs as seen on the STM32F334R8 and STM32F303K8. Edited ADC routines to allow for the simultaneous use of more than one ADC.

bogdanm 0:9b334a45a8ff 18 ##### DAC Peripheral features #####
bogdanm 0:9b334a45a8ff 19 ==============================================================================
bogdanm 0:9b334a45a8ff 20 [..]
bogdanm 0:9b334a45a8ff 21 *** DAC Channels ***
bogdanm 0:9b334a45a8ff 22 ====================
bogdanm 0:9b334a45a8ff 23 [..]
bogdanm 0:9b334a45a8ff 24 The device integrates two 12-bit Digital Analog Converters that can
bogdanm 0:9b334a45a8ff 25 be used independently or simultaneously (dual mode):
bogdanm 0:9b334a45a8ff 26 (#) DAC channel1 with DAC_OUT1 (PA4) as output
bogdanm 0:9b334a45a8ff 27 (#) DAC channel2 with DAC_OUT2 (PA5) as output
bogdanm 0:9b334a45a8ff 28
bogdanm 0:9b334a45a8ff 29 *** DAC Triggers ***
bogdanm 0:9b334a45a8ff 30 ====================
bogdanm 0:9b334a45a8ff 31 [..]
bogdanm 0:9b334a45a8ff 32 Digital to Analog conversion can be non-triggered using DAC_Trigger_None
bogdanm 0:9b334a45a8ff 33 and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register.
bogdanm 0:9b334a45a8ff 34 [..]
bogdanm 0:9b334a45a8ff 35 Digital to Analog conversion can be triggered by:
bogdanm 0:9b334a45a8ff 36 (#) External event: EXTI Line 9 (any GPIOx_Pin9) using DAC_Trigger_Ext_IT9.
bogdanm 0:9b334a45a8ff 37 The used pin (GPIOx_Pin9) must be configured in input mode.
bogdanm 0:9b334a45a8ff 38
bogdanm 0:9b334a45a8ff 39 (#) Timers TRGO: TIM2, TIM4, TIM6, TIM7, TIM9
bogdanm 0:9b334a45a8ff 40 (DAC_Trigger_T2_TRGO, DAC_Trigger_T4_TRGO...)
bogdanm 0:9b334a45a8ff 41
bogdanm 0:9b334a45a8ff 42 (#) Software using DAC_Trigger_Software
bogdanm 0:9b334a45a8ff 43
bogdanm 0:9b334a45a8ff 44 *** DAC Buffer mode feature ***
bogdanm 0:9b334a45a8ff 45 ===============================
bogdanm 0:9b334a45a8ff 46 [..]
bogdanm 0:9b334a45a8ff 47 Each DAC channel integrates an output buffer that can be used to
bogdanm 0:9b334a45a8ff 48 reduce the output impedance, and to drive external loads directly
bogdanm 0:9b334a45a8ff 49 without having to add an external operational amplifier.
bogdanm 0:9b334a45a8ff 50 To enable, the output buffer use
bogdanm 0:9b334a45a8ff 51 sConfig.DAC_OutputBuffer = DAC_OutputBuffer_Enable;
bogdanm 0:9b334a45a8ff 52 [..]
bogdanm 0:9b334a45a8ff 53 (@) Refer to the device datasheet for more details about output
bogdanm 0:9b334a45a8ff 54 impedance value with and without output buffer.
bogdanm 0:9b334a45a8ff 55
bogdanm 0:9b334a45a8ff 56 *** DAC wave generation feature ***
bogdanm 0:9b334a45a8ff 57 ===================================
bogdanm 0:9b334a45a8ff 58 [..]
bogdanm 0:9b334a45a8ff 59 Both DAC channels can be used to generate
bogdanm 0:9b334a45a8ff 60 (#) Noise wave
bogdanm 0:9b334a45a8ff 61 (#) Triangle wave
bogdanm 0:9b334a45a8ff 62
bogdanm 0:9b334a45a8ff 63 *** DAC data format ***
bogdanm 0:9b334a45a8ff 64 =======================
bogdanm 0:9b334a45a8ff 65 [..]
bogdanm 0:9b334a45a8ff 66 The DAC data format can be:
bogdanm 0:9b334a45a8ff 67 (#) 8-bit right alignment using DAC_ALIGN_8B_R
bogdanm 0:9b334a45a8ff 68 (#) 12-bit left alignment using DAC_ALIGN_12B_L
bogdanm 0:9b334a45a8ff 69 (#) 12-bit right alignment using DAC_ALIGN_12B_R
bogdanm 0:9b334a45a8ff 70
bogdanm 0:9b334a45a8ff 71 *** DAC data value to voltage correspondence ***
bogdanm 0:9b334a45a8ff 72 ================================================
bogdanm 0:9b334a45a8ff 73 [..]
bogdanm 0:9b334a45a8ff 74 The analog output voltage on each DAC channel pin is determined
bogdanm 0:9b334a45a8ff 75 by the following equation:
bogdanm 0:9b334a45a8ff 76 DAC_OUTx = VREF+ * DOR / 4095
bogdanm 0:9b334a45a8ff 77 with DOR is the Data Output Register
bogdanm 0:9b334a45a8ff 78 VEF+ is the input voltage reference (refer to the device datasheet)
bogdanm 0:9b334a45a8ff 79 e.g. To set DAC_OUT1 to 0.7V, use
bogdanm 0:9b334a45a8ff 80 Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V
bogdanm 0:9b334a45a8ff 81
bogdanm 0:9b334a45a8ff 82 *** DMA requests ***
bogdanm 0:9b334a45a8ff 83 =====================
bogdanm 0:9b334a45a8ff 84 [..]
bogdanm 0:9b334a45a8ff 85 A DMA1 request can be generated when an external trigger (but not
bogdanm 0:9b334a45a8ff 86 a software trigger) occurs if DMA1 requests are enabled using
bogdanm 0:9b334a45a8ff 87 HAL_DAC_Start_DMA()
bogdanm 0:9b334a45a8ff 88 [..]
bogdanm 0:9b334a45a8ff 89 DMA1 requests are mapped as following:
bogdanm 0:9b334a45a8ff 90 (#) DAC channel1 : mapped on DMA1 channel2 which must be
bogdanm 0:9b334a45a8ff 91 already configured
bogdanm 0:9b334a45a8ff 92 (#) DAC channel2 : mapped on DMA1 channel3 which must be
bogdanm 0:9b334a45a8ff 93 already configured
bogdanm 0:9b334a45a8ff 94
