mbed_official 76:aeb1df146756 919 [..] This section provides functions allowing to configure the DMA for ADC hannels.
mbed_official 76:aeb1df146756 920 Since converted channel values are stored into a unique data register,
mbed_official 76:aeb1df146756 921 it is useful to use DMA for conversion of more than one channel. This
mbed_official 76:aeb1df146756 922 avoids the loss of the data already stored in the ADC Data register.
mbed_official 76:aeb1df146756 923 When the DMA mode is enabled (using the ADC_DMACmd() function), after each
mbed_official 76:aeb1df146756 924 conversion of a channel, a DMA request is generated.
mbed_official 76:aeb1df146756 925
mbed_official 76:aeb1df146756 926 [..] Depending on the "DMA disable selection" configuration (using the
mbed_official 76:aeb1df146756 927 ADC_DMARequestModeConfig() function), at the end of the last DMA
mbed_official 76:aeb1df146756 928 transfer, two possibilities are allowed:
mbed_official 76:aeb1df146756 929 (+) No new DMA request is issued to the DMA controller (One Shot Mode)
mbed_official 76:aeb1df146756 930 (+) Requests can continue to be generated (Circular Mode).

mbed_official 76:aeb1df146756 988 ##### Interrupts and flags management functions #####
mbed_official 76:aeb1df146756 989 ===============================================================================
mbed_official 76:aeb1df146756 990 [..] This section provides functions allowing to configure the ADC Interrupts
mbed_official 76:aeb1df146756 991 and get the status and clear flags and Interrupts pending bits.
mbed_official 76:aeb1df146756 992
mbed_official 76:aeb1df146756 993 [..] The ADC provide 6 Interrupts sources and 11 Flags which can be divided into
mbed_official 76:aeb1df146756 994 3 groups:
mbed_official 76:aeb1df146756 995
mbed_official 76:aeb1df146756 996 *** Flags for ADC status ***
mbed_official 76:aeb1df146756 997 ======================================================
mbed_official 76:aeb1df146756 998 [..]
mbed_official 76:aeb1df146756 999 (+)Flags :
mbed_official 76:aeb1df146756 1000 (##) ADC_FLAG_ADRDY : This flag is set after the ADC has been enabled (bit ADEN=1)
mbed_official 76:aeb1df146756 1001 and when the ADC reaches a state where it is ready to accept conversion requests
mbed_official 76:aeb1df146756 1002 (##) ADC_FLAG_ADEN : This flag is set by software to enable the ADC.
mbed_official 76:aeb1df146756 1003 The ADC will be effectively ready to operate once the ADRDY flag has been set.
mbed_official 76:aeb1df146756 1004 (##) ADC_FLAG_ADDIS : This flag is cleared once the ADC is effectively
mbed_official 76:aeb1df146756 1005 disabled.
mbed_official 76:aeb1df146756 1006 (##) ADC_FLAG_ADSTART : This flag is cleared after the execution of
mbed_official 76:aeb1df146756 1007 ADC_StopOfConversion() function, at the same time as the ADSTP bit is
mbed_official 76:aeb1df146756 1008 cleared by hardware
mbed_official 76:aeb1df146756 1009 (##) ADC_FLAG_ADSTP : This flag is cleared by hardware when the conversion
mbed_official 76:aeb1df146756 1010 is effectively discarded and the ADC is ready to accept a new start conversion
mbed_official 76:aeb1df146756 1011 (##) ADC_FLAG_ADCAL : This flag is set once the calibration is complete.
mbed_official 76:aeb1df146756 1012
mbed_official 76:aeb1df146756 1013 (+)Interrupts
mbed_official 76:aeb1df146756 1014 (##) ADC_IT_ADRDY : specifies the interrupt source for ADC ready event.
mbed_official 76:aeb1df146756 1015
mbed_official 76:aeb1df146756 1016 *** Flags and Interrupts for ADC channel conversion ***

mbed_official 76:aeb1df146756 1018 [..]
mbed_official 76:aeb1df146756 1019 (+)Flags :
mbed_official 76:aeb1df146756 1020 (##) ADC_FLAG_EOC : This flag is set by hardware at the end of each conversion
mbed_official 76:aeb1df146756 1021 of a channel when a new data result is available in the data register
mbed_official 76:aeb1df146756 1022 (##) ADC_FLAG_EOSEQ : This bit is set by hardware at the end of the conversion
mbed_official 76:aeb1df146756 1023 of a sequence of channels selected by ADC_ChannelConfig() function.
mbed_official 76:aeb1df146756 1024 (##) ADC_FLAG_EOSMP : This bit is set by hardware at the end of the sampling phase.
mbed_official 76:aeb1df146756 1025 (##) ADC_FLAG_OVR : This flag is set by hardware when an overrun occurs,
mbed_official 76:aeb1df146756 1026 meaning that a new conversion has complete while the EOC flag was already set.
mbed_official 76:aeb1df146756 1027
mbed_official 76:aeb1df146756 1028 (+)Interrupts :
mbed_official 76:aeb1df146756 1029 (##) ADC_IT_EOC : specifies the interrupt source for end of conversion event.
mbed_official 76:aeb1df146756 1030 (##) ADC_IT_EOSEQ : specifies the interrupt source for end of sequence event.
mbed_official 76:aeb1df146756 1031 (##) ADC_IT_EOSMP : specifies the interrupt source for end of sampling event.
mbed_official 76:aeb1df146756 1032 (##) ADC_IT_OVR : specifies the interrupt source for Overrun detection
mbed_official 76:aeb1df146756 1033 event.

mbed_official 76:aeb1df146756 1038 (+)Flags :
mbed_official 76:aeb1df146756 1039 (##) ADC_FLAG_AWD: This flag is set by hardware when the converted
mbed_official 76:aeb1df146756 1040 voltage crosses the values programmed thrsholds
mbed_official 76:aeb1df146756 1041
mbed_official 76:aeb1df146756 1042 (+)Interrupts :

mbed_official 76:aeb1df146756 1044 event.
mbed_official 76:aeb1df146756 1045
mbed_official 76:aeb1df146756 1046 [..] The user should identify which mode will be used in his application to
mbed_official 76:aeb1df146756 1047 manage the ADC controller events: Polling mode or Interrupt mode.
mbed_official 76:aeb1df146756 1048
mbed_official 76:aeb1df146756 1049 [..] In the Polling Mode it is advised to use the following functions:
mbed_official 76:aeb1df146756 1050 (+) ADC_GetFlagStatus() : to check if flags events occur.
mbed_official 76:aeb1df146756 1051 (+) ADC_ClearFlag() : to clear the flags events.
mbed_official 76:aeb1df146756 1052
mbed_official 76:aeb1df146756 1053 [..] In the Interrupt Mode it is advised to use the following functions:
mbed_official 76:aeb1df146756 1054 (+) ADC_ITConfig() : to enable or disable the interrupt source.
mbed_official 76:aeb1df146756 1055 (+) ADC_GetITStatus() : to check if Interrupt occurs.
mbed_official 76:aeb1df146756 1056 (+) ADC_ClearITPendingBit() : to clear the Interrupt pending Bit
mbed_official 76:aeb1df146756 1057 (corresponding Flag).
