##### DAC Peripheral features ##### |
|
17 |
============================================================================== |
|
18 |
[..] |
|
19 |
*** DAC Channels *** |
|
20 |
==================== |
|
21 |
[..] |
|
22 |
STM32F0 devices integrates no, one or two 12-bit Digital Analog Converters. |
|
23 |
STM32F05x devices have one converter (channel1) |
|
24 |
STM32F07x & STM32F09x devices have two converters (i.e. channel1 & channel2) |
|
25 |
|
|
26 |
When 2 converters are present (i.e. channel1 & channel2) they |
|
27 |
can be used independently or simultaneously (dual mode): |
|
28 |
(#) DAC channel1 with DAC_OUT1 (PA4) as output |
|
29 |
(#) DAC channel2 with DAC_OUT2 (PA5) as output |
|
30 |
|
|
31 |
*** DAC Triggers *** |
|
32 |
==================== |
|
33 |
[..] |
|
34 |
Digital to Analog conversion can be non-triggered using DAC_TRIGGER_NONE |
|
35 |
and DAC_OUT1/DAC_OUT2 is available once writing to DHRx register. |
|
36 |
[..] |
|
37 |
Digital to Analog conversion can be triggered by: |
|
38 |
(#) External event: EXTI Line 9 (any GPIOx_PIN_9) using DAC_TRIGGER_EXT_IT9. |
|
39 |
The used pin (GPIOx_PIN_9) must be configured in input mode. |
|
40 |
|
|
41 |
(#) Timers TRGO: TIM2, TIM3, TIM6, and TIM15 |
|
42 |
(DAC_TRIGGER_T2_TRGO, DAC_TRIGGER_T3_TRGO...) |
|
43 |
|
|
44 |
(#) Software using DAC_TRIGGER_SOFTWARE |
|
45 |
|
|
46 |
*** DAC Buffer mode feature *** |
|
47 |
=============================== |
|
48 |
[..] |
|
49 |
Each DAC channel integrates an output buffer that can be used to |
|
50 |
reduce the output impedance, and to drive external loads directly |
|
51 |
without having to add an external operational amplifier. |
|
52 |
To enable, the output buffer use |
|
53 |
sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE; |
|
54 |
[..] |
|
55 |
(@) Refer to the device datasheet for more details about output |
|
56 |
impedance value with and without output buffer. |
|
57 |
|
|
58 |
*** GPIO configurations guidelines *** |
|
59 |
===================== |
|
60 |
[..] |
|
61 |
When a DAC channel is used (ex channel1 on PA4) and the other is not |
|
62 |
(ex channel1 on PA5 is configured in Analog and disabled). |
|
63 |
Channel1 may disturb channel2 as coupling effect. |
|
64 |
Note that there is no coupling on channel2 as soon as channel2 is turned on. |
|
65 |
Coupling on adjacent channel could be avoided as follows: |
|
66 |
when unused PA5 is configured as INPUT PULL-UP or DOWN. |
|
67 |
PA5 is configured in ANALOG just before it is turned on. |
|
68 |
|
|
69 |
*** DAC wave generation feature *** |
|
70 |
=================================== |
|
71 |
[..] |
|
72 |
Both DAC channels can be used to generate |
|
73 |
(#) Noise wave |
|
74 |
(#) Triangle wave |
|
75 |
|
|
76 |
*** DAC data format *** |
|
77 |
======================= |
|
78 |
[..] |
|
79 |
The DAC data format can be: |
|
80 |
(#) 8-bit right alignment using DAC_ALIGN_8B_R |
|
81 |
(#) 12-bit left alignment using DAC_ALIGN_12B_L |
|
82 |
(#) 12-bit right alignment using DAC_ALIGN_12B_R |
|
83 |
|
|
84 |
*** DAC data value to voltage correspondance *** |
|
85 |
================================================ |
|
86 |
[..] |
|
87 |
The analog output voltage on each DAC channel pin is determined |
|
88 |
by the following equation: |
|
89 |
[..] |
|
90 |
DAC_OUTx = VREF+ * DOR / 4095 |
|
91 |
(+) with DOR is the Data Output Register |
|
92 |
[..] |
|
93 |
VEF+ is the input voltage reference (refer to the device datasheet) |
|
94 |
[..] |
|
95 |
e.g. To set DAC_OUT1 to 0.7V, use |
|
96 |
(+) Assuming that VREF+ = 3.3V, DAC_OUT1 = (3.3 * 868) / 4095 = 0.7V |
|
97 |
|
|
98 |
*** DMA requests *** |
|
99 |
===================== |
|
100 |
[..] |
|
101 |
A DMA1 request can be generated when an external trigger (but not |
|
102 |
a software trigger) occurs if DMA1 requests are enabled using |
|
103 |
HAL_DAC_Start_DMA() |
|
104 |
[..] |
|
105 |
DMA1 requests are mapped as following: |
|
106 |
(#) DAC channel1 : mapped on DMA1 channel3 which must be |
|
107 |
already configured |
|
108 |
(#) DAC channel2 : mapped on DMA1 channel4 which must be |
|
109 |
already configured |
|
110 |
|
|
111 |
(@) For Dual mode and specific signal (Triangle and noise) generation please |
|
112 |
refer to Extended Features Driver description |
|
113 |
STM32F0 devices with one channel (one converting capability) does not |
|
114 |
support Dual mode and specific signal (Triangle and noise) generation. |
|
115 |
|
|
116 |
##### How to use this driver ##### |
|
117 |
============================================================================== |
|
118 |
[..] |
|
119 |
(+) DAC APB clock must be enabled to get write access to DAC |
|
120 |
registers using HAL_DAC_Init() |
|
121 |
(+) Configure DAC_OUTx (DAC_OUT1: PA4, DAC_OUT2: PA5) in analog mode. |
|
122 |
(+) Configure the DAC channel using HAL_DAC_ConfigChannel() function. |
|
123 |
(+) Enable the DAC channel using HAL_DAC_Start() or HAL_DAC_Start_DMA() functions. |
|
124 |
|
|
125 |
*** Polling mode IO operation *** |
|
126 |
================================= |
|
127 |
[..] |
|
128 |
(+) Start the DAC peripheral using HAL_DAC_Start() |
|
129 |
(+) To read the DAC last data output value, use the HAL_DAC_GetValue() function. |
|
130 |
(+) Stop the DAC peripheral using HAL_DAC_Stop() |
|
131 |
|
|
132 |
*** DMA mode IO operation *** |
|
133 |
============================== |
|
134 |
[..] |
|
135 |

|
136 |
of data to be transferred at each end of conversion |
|
137 |
(+) At the middle of data transfer HAL_DAC_ConvHalfCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2() |
|
138 |
function is executed and user can add his own code by customization of function pointer |
|
139 |
HAL_DAC_ConvHalfCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2() |
|
140 |
(+) At The end of data transfer HAL_DAC_ConvCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2() |
|
141 |
function is executed and user can add his own code by customization of function pointer |
|
142 |
HAL_DAC_ConvCpltCallbackCh1() or HAL_DACEx_ConvHalfCpltCallbackCh2() |
|
143 |
(+) In case of transfer Error, HAL_DAC_ErrorCallbackCh1() function is executed and user can |
|
144 |
add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1 |
|
145 |
(+) In case of DMA underrun, DAC interruption triggers and execute internal function HAL_DAC_IRQHandler. |
|
146 |
HAL_DAC_DMAUnderrunCallbackCh1() or HAL_DACEx_DMAUnderrunCallbackCh2() |
|
147 |
function is executed and user can add his own code by customization of function pointer |

|
149 |
add his own code by customization of function pointer HAL_DAC_ErrorCallbackCh1() |
|
150 |
(+) Stop the DAC peripheral using HAL_DAC_Stop_DMA() |
|
151 |
|
|
152 |
