Abstract
A system and method for dynamically reconfiguring a touch sensor controller that transmits signals to and receives signals from an electrode array of a capacitance sensitive touch sensor, wherein multiplexing of signals to and from the controller enables reconfiguration of input and output pins to thereby increase the functions and versatility of a touch sensor controller.
Claims22
A dynamically configurable touch sensor controller, said touch sensor controller comprising:
- a plurality of pins that function as either input or output pins;
- a drive circuit for generating drive signals;
- a sense circuit for measuring sense signals, wherein each of the plurality of pins may be coupled to the drive circuit and to the sense circuit, such that each of the plurality of pins may function as a drive pin for transmitting a drive signal or as a sense pin for receiving a sense signal;
- a control means for dynamically coupling each of the plurality of pins to the drive circuit or to the sense circuit, wherein the control means may change the connection of any of the plurality of pins so that any of the plurality of pins may function as a drive pin or as a sense pin.

A method for dynamically configuring a touch sensor controller, said method comprising:
- providing a plurality of pins that function as either input or output pins, providing a drive circuit for generating drive signals and a sense circuit for measuring sense signals, wherein each of the plurality of pins may be coupled to the drive circuit and to the sense circuit, such that each of the plurality of pins may function as a drive pin for transmitting a drive signal or as a sense pin for receiving a sense signal;
- and
- dynamically coupling each of the plurality of pins to the drive circuit or to the sense circuit using a control means, wherein the control means may change the connection of any of the plurality of pins so that any of the plurality of pins may function as a drive pin or as a sense pin.
