Subject: RE: [PATCH] Add the LED burst trigger

Hi all,

I think Pavel's suggestion is a good idea, I'm starting to write another trigger named Morse code trigger.

I prefer to keeping this burst trigger and add another Morse code trigger for different application. But I know the Morse code trigger will be the super set of the burst. Say the patten ... Morse code is same as the 3 times burst blinking.

Anyway, after I finish that trigger, let community to decide which one will be adapted, or both.

Any suggestion about the new Morse trigger, please let me know.

Thank you Pavel.

Joe
