hello dear forum,

 

I am trying to take 500 samples from STM32F103RC ADC with DMA

 

I wanna know if the ADC sampling clock equal to ADC clock or 

system clock 

 

for example ;

 

If I choose ADC clock = P2clock / 8 = 9 MHz 

and I choose sampling time 239.5 clock 

 

does this mean that 500 samples last ( 239 * 500 ) / 9000000 = 13 milisecond ?

 

thank you
