although i hv been working with controllers since a year but ol was at very small level...such at basic level...its only now i hv got in touch wid concepts of interrupt, timer and pwm....so i may be wrong somewhere and obviously 'll appreciate any help into this....
i want to operate ultrasound transducers for distance measurement purpose...as i got to know dat they work at only 40 kHz...now my problem is dat can v produce this frequency wid the help of atmega16PU...as frequency produced depends on prescaler settings...either u consider overflow operation or compare operation...i m not able to decide dat which way i shall produce this frequency with this microcntrllr...
pls reply as soon as u can...
