I need to know what is the maximum number of touch pads a given Teensy device can support. The documentation here
https://www.pjrc.com/teensy/td_libs_CapacitiveSensor.html
says that a pair of pins are required per pad. Do both pins need to be "Touch" pins? I see that pads can share a send pin. So if one Touch pin must be send, does that mean that the maximum number of touch pads is the number of available pins minus 1 for the send pin?
I need to scan all the pads as fast as possible. Assuming the user is touching a pad connected to the device ground and the sensing pads are touched directly, how fast can each be read?
If more than one send pin is assigned might it be possible to read more than one pin in parallel?
