5.8 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 “
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: 274Hz (
Lo
) and 1kHz (
Hi
). The
value of frequency in the upper range avoids the flicker effect visible in the
cameras.
5.9 Minimum level of brightness
The function of setting the minimum level of brightness (
OFS
) has been
implemented in the PX163+ device, which can be set in the range from o to
100.
