Full PWM Power to Zero Power fails. about pibits HOT 4 CLOSED

Thanks; that's because setting =0 just removes the 'turn on' trigger, and
relies on the 'turn off' at the end of the current pulse to turn it off.
However, if you've set width to 2000 then there is no 'turn off' as it is
on 100%. So, I remove the 'turn on' trigger and the output stays on for
ever. Will fix.

When driving a servo it is important we don't cut a pulse short when going
to =0, which is why it waits for the current pulse to end and set the
output off. However, =2000 is a special case, and I'll just set the output
off immediately.

Hi,
Recently starting using servoblaster to power an LED array via a
Darlington Array; I set the following options in /etc/init.d/servoblaster:

OPTS='--p1pins=12 --p5pins= --min=1 --max=2000'

When setting:

echo 0=2000 > /dev/servoblaster

The LED is set to full brightness correctly. Then, setting:

echo 0=0 > /dev/servoblaster

Does nothing. However; setting it to a non-maximum value first, then
setting to zero does work! ie:

echo 0=1999 > /dev/servoblaster
echo 0=0 > /dev/servoblaster

Sorry haven't got around to this yet :) Will hopefully sort it today!
