I was researching about the TSC (Touch Sensing Controller) of my Board Nucleo L053R8 and I found that there it has something called "the analog switch".
The TSC is composed of several groups. Each group is composed of 4 I/Os being one of them dedicated for one reference capacitor (Cs) while the other 3 are dedicated for connecting capacitive buttons. What I suspect is that one analog switch belong to one group, and it can be used to connect internally the I/Os of a group.
Does anyone have experience with this topic? any code example? Mi goal is to connect internally and programatically two I/Os for certain time and after separate them.
Thank you all. Any help is highly appreciated.
