How and when to use some functions of ADC - STM8L052C6

[NMart.4]

Hello guys

I am learning to use the peripheral ADC on uC called STM8L052C6 of the family STM8L , i have already read the chapter about ADC in the reference manual and in the datasheet.

I read also the library about ADC, i mean the file .c and .h.

There are 2 functions that for me are unclear :

1. ADC_SamplingTimeConfig
2. ADC_SchmittTriggerConfig

There is someone who can explain to me this functions in a clear way with seample and functional examples?

kind regards
