the little windows machine is running now.
much more performance than the raspberry
and now the delay commands have the right timing
on the raspberry, the longer the systems was running, the slower each command was performed. having the raspberry running for two days results in a very laggy interface. each click took seconds to be executed…
but the shutdown of the projectors is still not working to 100%
actually i am performing the whole shutdown sequence twice. one task fo each projector executes a shutdown command two times with a delay of 750ms. one sequence means all 8 projectors. that seems to solve the probem at the moment.
changing to the win system leaves mostly one projector running, whereas with the raspberry it was mostle two or three.
