Difference between SamplingTime common 1 and SamplingTime common 2

I am working with ADC in STM32G070RB nucleo board. While configuring I have seen SamplingTime common 1 and SamplingTime common 2. What is the difference between these two?

Hello @mohamed_husain

Both Sampling Time common 1 (SMP1) and Sampling Time common 2 (SMP2) do the exact same job which is to choose the sampling time that applies to the ADC Channels. But, for each channel of the ADC, you can choose between SMP1 and SMP2 to select sampling time of this channel using the SMPSEL[18:0].

For more details, refer to the chapter 14 of the RM0454 Rev 5.
