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.
