I would like to use a circle type electrode as both button type capsensor and other use.
so, I tried use a amux to change path to the circle type electrode.
if amux set 0, the path is ( first setting )
CapSense_CSD -> mux -> the circle type electrode
if amux set 1, the path is ( second setting )
another circuit -> mux -> the circle type electrode
the problem is.. when i use the first setting the capsensor button shows always ON state.
when mux is disabled, capsensor works fine. so I think activated mux should changes capsensor working condition.
I have thought that the mux is just switch.... the above condition says another properties of mux must be exist..
Is it possible for you to give more information. Please give us your schematic and project.
