mbed_official 157:90e3acc479a2 1053
mbed_official 157:90e3acc479a2 1054 [..] To configure a regular sequence of channels use:
mbed_official 157:90e3acc479a2 1055 (#) ADC_RegularChannelConfig()
mbed_official 157:90e3acc479a2 1056 this fuction allows:

mbed_official 157:90e3acc479a2 1058 (++) Configure the sampling time for each channel
mbed_official 157:90e3acc479a2 1059
mbed_official 157:90e3acc479a2 1060 (#) ADC_RegularChannelSequencerLengthConfig() to set the length of the regular sequencer
mbed_official 157:90e3acc479a2 1061
mbed_official 157:90e3acc479a2 1062 [..] The regular trigger is configured using the following functions:

mbed_official 157:90e3acc479a2 1081 automatically cleared.
mbed_official 157:90e3acc479a2 1082
mbed_official 157:90e3acc479a2 1083 [..] To configure the discontinous mode, the following functions should be used:
mbed_official 157:90e3acc479a2 1084 (#) ADC_DiscModeChannelCountConfig() to configure the number of discontinuous channel to be converted.
mbed_official 157:90e3acc479a2 1085 (#) ADC_DiscModeCmd() to enable the discontinuous mode.
