ServoStik & LEDBlinky Problem
« on: March 23, 2014, 02:58:52 am »
Hey guys,
Just got my new ServoStik's set up in my cab with LEDBlinky.  Very impressed with how easy it was to get everything running and automatically switching! But there is one problem.. It seems that LEDBlinky doesn't check the current orientation of the sticks BEFORE it attempts to switch them! So if the stick are in 4 way mode from play donkey kong, and I select pacman, the sticks attempt to change to 4 way AGAIN.  I can't imagine this is good for the servos. Anybody know if this is overlooked behavior? Or am I missing something?

Thanks in advance,
Daniel

*EDIT* Reboot seems to have fixed this? Should have called IT....

I was under the impression that the servostick does not report the state back to the USB (the only connectors are to power the motor AFAIK). I think it is by design that the motor stops if it encounters any friction.
It is possible to keep track in software what movements were made (and do an "initialize move") , but it is not a report of the actual state and therefore may not be correct. Perhaps this is what LEDBlinky does?

Perfectly normal operation. As Felsir stated the servo doesn't have any positioning sensors. The control board just sends out normal/reverse polarity current and senses for resistance build up in the motor when the travel limit is reached. So without software or hardware position sensing it will send a voltage pulse for each game started even if both games are 4or8way being started back to back.


good day.
