[PD] Marionette Control

[Winfried Ritsch]

Hello,


We build just an PIC Board controlling 24 channeles of motors with 
pulsmodulated output, and a FET Board, to controll them.

But if you want it easy, just use the paralell out and there is a simple 
realtime linuxdevice (rtai) controlling eight to twelve servos, which have a 
puls-coded interface and then writing with pd to this device.
