Latest news - shutter control in the middle of taking a picture.
QHY kindly sent me the details of the circuit as per attached pics for the shutter circuit of the QHY9m.
The chip is an L298P - easily found on google -
it's a dual full bridge driver.
It's NOT just a matter of connecting 2 wires up to do this modification.
I'll have to think about it.
I can't just drive pins 7,9,13,15 as I would be back feeding voltage into
their sources - another chip - not shown.
Anyway - I have a starting point to work with.
Also - QHY may put this idea into their software on the next revision
which would be fantastic & a lot easier than trying to wire in hardware.
cheers
Allan
