Hi Guys,I’m in the process of making a failsafe device for a UAV using a Basic Stamp and a few other bits. I picked myself up a MUX Chip as used in the Ardupilot but I’m having trouble getting it to work. After looking at the Ardupilot layout, I noticed that the GND of the MUX Chip in the Ardupilot does not seem to be connected to anything? Is this correct??Is there a trick to connecting this thing up? Thanks.I am powering it out of the regulated 5V out of the Basic Stamp (pin 21) .The Mux Chip and a few 3mm Led’s are the only things drawing current from the Stamp.Thanks.

Update!
All working now, I forgot to tie pin 15 (G) on the Mux chip to GND.
With out doing that the chip is basically turned off.
Hmmmmmmmmmmmmmmmmmmmmmmmmmm :)
