rambinator Posted February 20, 2006 Report Share Posted February 20, 2006 I have this jog/shuttle-wheel and I want to build it into my midibox lc.I do not understand the meaning of the different pins in the datasheet.http://www3.alps.co.jp/WebObjects/catalog.woa/PDF/E/Switch/Encoder/SRGP/SRGP.PDFcan anybody help me with this?cheers,rambinator Quote Link to comment Share on other sites More sharing options...

rambinator Posted February 20, 2006 Author Report Share Posted February 20, 2006 Thanks, I thought I was the first one to find this thing :)So it seems that only the jog-part is usefull for mblc Quote Link to comment Share on other sites More sharing options...
moebius Posted February 20, 2006 Report Share Posted February 20, 2006 So it seems that only the jog-part is usefull for mblcYup - with no code modifications... but a clever coder would scan for the shuttle ring position and then send jog wheel messages with different speeds (per amount of turn) to emulate shuttle :DI'm no clever coder, M Quote Link to comment Share on other sites More sharing options...
rambinator Posted February 21, 2006 Author Report Share Posted February 21, 2006 hmmm. maybe for another project, but on the midibox lc there are no spare dins for such gimmicks. Quote Link to comment Share on other sites More sharing options...

One for direction and other 3 others have various bit patterns for different rotation angles.Moebius Quote Link to comment Share on other sites More sharing options...
Wild_Weasel Posted February 24, 2006 Report Share Posted February 24, 2006 Hi!I would be very happy if someone could code something for the shuttle ring. I started experimenting with 74HCxx chips (Inverter and NOR) to get direction and position. Not very elegant though and space consuming. I am no assembler coder and don't know how much effort this would be. I am thinking of emulating a pot with the shuttle (with jumps of course)RegardsMichael Quote Link to comment Share on other sites More sharing options...
