    摘要： A multi-channel capacitive sensor comprises a sample capacitor having first and second terminals, a first diode having a first terminal coupled to the second terminal of the sample capacitor and a second terminal coupled to a first sense electrode, and a second diode having a first terminal coupled to the second terminal of the sample capacitor and a second terminal coupled to a second sense electrode. The sample capacitor and diodes are coupled to a control circuit. The control circuit is operable to apply a drive signal to the first terminal of the sample capacitor while simultaneously applying a bias signal to the second terminal of one or other of the diodes to prevent the diode from conducting the drive signal.

    摘要： In one embodiment, a method comprises detecting, by a hardware accelerator, that a value has been written to a first location of a memory, the first location identified by a first address. The method further includes adding the value to an accumulated value stored in an accumulator register of the hardware accelerator and storing the result in the accumulator register. The method further includes comparing the value to a maximum value stored in a first register of the hardware accelerator and overwriting the maximum value with the value if the value is greater than the maximum value. The method also includes comparing the value to a minimum value stored in a second register of the hardware accelerator and overwriting the minimum value with the value if the value is less than the minimum value.

    摘要： In certain embodiments, a multi-channel capacitive sensor for measuring capacitances of sense electrodes to a system reference potential comprises a sample capacitor having first and second terminals. The sensor comprises a first diode having a first terminal coupled to the second terminal of the sample capacitor and a second terminal coupled to a first sense electrode, and comprises a second diode having a first terminal coupled to the second terminal of the sample capacitor and a second terminal coupled to a second sense electrode. A control circuit is operable to apply a drive signal to the first terminal of the sample capacitor and apply a bias signal to the respective second terminals of at least one of the first and second diodes so as to selectively prevent the at least one of the first and second diodes from conducting the drive signal to respectively connected sense electrodes.
