Reading Analogue Voltage signal using Arduino Due

hey everybody,

i'm using arduino due microcontroller frequency (clock rate) = 84 mhz
and i'm trying read voltage signal through normal socket (power frequency) = 50 hz through step down transformer ..
and need take 260 sample signals voltage sine wave .. !
so how manage frequency of microcontroller perform such task .. !

thanks lot ..

you don't manage frequency of micro, manage frequency of readings.  did figure of 260 come , on period need take readings ?  give interval between readings can used in program.

code: [select]

set start time using millis() or micros() appropriate
start of loop
  if - start time >= reading interval
    take reading
    reset start time
  end if
end of loop
 
look @ blinkwithoutdelay example program see example of using technique.
