摘要： In one embodiment, a method for determining the location of a touch on a touch sensor includes receiving input signals in response to a touch proximate to a location on the touch sensor. Each input signal may have a total capacitance that includes a first capacitance associated with the touch and a second capacitance that is parasitic capacitance. The parasitic capacitance of one or more of the input signals may be adjusted to result in the second capacitance of each of the input signals being substantially equal. An average capacitance of the adjusted input signals may be calculated. The location of the touch on the touch sensor may then be determined based on a comparison of the total capacitance of each of the input signals and the average capacitance of the input signals.

摘要： A single-wire bootloader software architecture is disclosed that interfaces with any host device that has a serial port to program memory of a target device using only a single general-purpose I/O pin. The single-wire bootloader does not require any chip hardware resource modules. Instead, the single-wire bootloader implements a single-wire UART in software that monitors a single general-purpose I/O pin for commands from the host device.

摘要： A method of one embodiment includes generating, by a touch-sensing device, a first signal comprising information identifying a first electrode line of an electrode array of the touch-sensing device, the first signal having a first strength. The first electrode sends the first signal to a stylus, which receives the first signal, the first signal having a received strength. The stylus sends a second signal comprising information based on the received first signal, and the touch-sensing device receives the second signal. A position of the stylus is determined based at least in part on the information identifying the first electrode line and the received strength of the first signal.

摘要： In one embodiment, a stylus receives a signal, the stylus being able to wirelessly transmit signals to and receive signals from a device, and the stylus having a plurality of electrodes disposed in a tip of the stylus. The stylus compares a first value of the signal to a first threshold and determines whether to start a timing period based at least in part on this comparison. If the timing period is started, the stylus compares a second value of the signal to a second threshold and determines whether to stop the timing period based at least in part on this second comparison. If the timing period is stopped, the stylus determines whether the duration of the timing period is within a pre-determined range of timing period values. If so, the stylus processes the signal.
