6.6 Frequency of PWM signals
The
Frq
function allows you to set the base frequency to drive LEDs. This
function is extremely useful for applications in the television industry. By using
the "
flicker free
" technology, you can avoid an unpleasant image flicker effect
caused by a lack of appropriate synchronization of LED driving signal. The
user has two available frequency: 274 Hz (function
Lo
) and 1000 Hz (
Hi
).
The value of frequency in the upper range avoids the flicker effect visible
in the cameras.
