Hello, I want o create a sinus wave using DC singnal with RTC.
What is the general ways of accomplishing it?
from where i get a DC source?
if i count from 0 till 1000 an the till 0 again its not creating a sinus wave as shown bellow.
What is the method for creating a sinus wave?
Thanks.

Use a lookup table with entries containing the value for that step in the sine wave. (As an alternative you could do an on the fly calculation for that value.) You could then feed that value to a DAC. Another way would be to control the duty cycle of a PWM output. The PWM frequency would need to be many times higher than the frequency of the required sinewave.

Hello, I am looking the API option in RTC to make the TICk independant of the operating system.
How its called in the API shown bellow?
Thanks.
