Hi Viesturs.

Finally I can send to you the HAL component for the "blink" function as I
explained before.
This is my first component I wrote .... so for sure somebody else can do it
better than I did .
Anyway let me know if this component is useful for your needs (for me it
is) . ;-) .
You have to add one or more instances of the component to the servo thread
(1ms).

Regards

Alex
