I've recently updated from a >6 month old version of CHDK to ver0.9.6-706, dated Feb 5 2009.
Under the 'Scripting Parameters' menu there is now a ---shutdown--- entry followed by 'pulse length' and 'value'.
Can anyone explain how these are used, or better yet, point me to some documentation? My searches so far have been fruitless.
Thanks in advance,
Angus
