yihui 5:b8c02645e6af 1051
yihui 5:b8c02645e6af 1052 [..] This section provides functions allowing to manage the ADC regular channels.
yihui 5:b8c02645e6af 1053
yihui 5:b8c02645e6af 1054 [..] To configure a regular sequence of channels use:
yihui 5:b8c02645e6af 1055 (#) ADC_RegularChannelConfig()
yihui 5:b8c02645e6af 1056 this fuction allows:
yihui 5:b8c02645e6af 1057 (++) Configure the rank in the regular group sequencer for each channel
yihui 5:b8c02645e6af 1058 (++) Configure the sampling time for each channel
yihui 5:b8c02645e6af 1059
yihui 5:b8c02645e6af 1060 (#) ADC_RegularChannelSequencerLengthConfig() to set the length of the regular sequencer
yihui 5:b8c02645e6af 1061
yihui 5:b8c02645e6af 1062 [..] The regular trigger is configured using the following functions:
yihui 5:b8c02645e6af 1063 (#) ADC_SelectExternalTrigger()
yihui 5:b8c02645e6af 1064 (#) ADC_ExternalTriggerPolarityConfig()
yihui 5:b8c02645e6af 1065
yihui 5:b8c02645e6af 1066 [..] The start and the stop conversion are controlled by:
yihui 5:b8c02645e6af 1067 (#) ADC_StartConversion()
yihui 5:b8c02645e6af 1068 (#) ADC_StopConversion()
yihui 5:b8c02645e6af 1069
yihui 5:b8c02645e6af 1070 [..]
yihui 5:b8c02645e6af 1071 (@)Please Note that the following features for regular channels are configurated
yihui 5:b8c02645e6af 1072 using the ADC_Init() function :
yihui 5:b8c02645e6af 1073 (++) continuous mode activation
yihui 5:b8c02645e6af 1074 (++) Resolution
yihui 5:b8c02645e6af 1075 (++) Data Alignement
yihui 5:b8c02645e6af 1076 (++) Overrun Mode.
yihui 5:b8c02645e6af 1077
yihui 5:b8c02645e6af 1078 [..] Get the conversion data: This subsection provides an important function in
yihui 5:b8c02645e6af 1079 the ADC peripheral since it returns the converted data of the current
yihui 5:b8c02645e6af 1080 regular channel. When the Conversion value is read, the EOC Flag is
yihui 5:b8c02645e6af 1081 automatically cleared.
yihui 5:b8c02645e6af 1082
yihui 5:b8c02645e6af 1083 [..] To configure the discontinous mode, the following functions should be used:
yihui 5:b8c02645e6af 1084 (#) ADC_DiscModeChannelCountConfig() to configure the number of discontinuous channel to be converted.
yihui 5:b8c02645e6af 1085 (#) ADC_DiscModeCmd() to enable the discontinuous mode.
yihui 5:b8c02645e6af 1086
yihui 5:b8c02645e6af 1087 [..] To configure and enable/disable the Channel offset use the functions:
yihui 5:b8c02645e6af 1088 (++) ADC_SetChannelOffset1()
yihui 5:b8c02645e6af 1089 (++) ADC_SetChannelOffset2()
yihui 5:b8c02645e6af 1090 (++) ADC_SetChannelOffset3()
yihui 5:b8c02645e6af 1091 (++) ADC_SetChannelOffset4()
yihui 5:b8c02645e6af 1092 (++) ADC_ChannelOffset1Cmd()
yihui 5:b8c02645e6af 1093 (++) ADC_ChannelOffset2Cmd()
yihui 5:b8c02645e6af 1094 (++) ADC_ChannelOffset3Cmd()

yihui 5:b8c02645e6af 1730 [..] This section provides functions allowing to configure the DMA for ADC regular
yihui 5:b8c02645e6af 1731 channels. Since converted regular channel values are stored into a unique data register,
yihui 5:b8c02645e6af 1732 it is useful to use DMA for conversion of more than one regular channel. This
yihui 5:b8c02645e6af 1733 avoids the loss of the data already stored in the ADC Data register.
yihui 5:b8c02645e6af 1734
yihui 5:b8c02645e6af 1735 (#) ADC_DMACmd() function is used to enable the ADC DMA mode, after each
yihui 5:b8c02645e6af 1736 conversion of a regular channel, a DMA request is generated.
yihui 5:b8c02645e6af 1737 (#) ADC_DMAConfig() function is used to select between the one shot DMA mode
yihui 5:b8c02645e6af 1738 or the circular DMA mode

yihui 5:b8c02645e6af 2100
yihui 5:b8c02645e6af 2101 In the Polling Mode it is advised to use the following functions:
yihui 5:b8c02645e6af 2102 - ADC_GetFlagStatus() : to check if flags events occur.
yihui 5:b8c02645e6af 2103 - ADC_ClearFlag() : to clear the flags events.
yihui 5:b8c02645e6af 2104
yihui 5:b8c02645e6af 2105 In the Interrupt Mode it is advised to use the following functions:
yihui 5:b8c02645e6af 2106 - ADC_ITConfig() : to enable or disable the interrupt source.
yihui 5:b8c02645e6af 2107 - ADC_GetITStatus() : to check if Interrupt occurs.
