Summary: | Methods and devices are disclosed for increasing low-force accuracy at a device, such as a pen or a stylus which are used for communicating with a digitizer. An example method describes detecting an amount of force at the tip of the device and generating a voltage associated with the amount of force. The example method further includes logarithmically sampling the voltage to produce a digital value associated with the amount of force and determining whether the device is operating in an inking state based on the digital value. An example device may include a pressure sensor to detect an amount of force and generate a voltage associated with the amount of force, a sampling circuit to sample the voltage to produce a digital value, a memory and a processor in communication with the memory to determine whether the device is operating in an inking state based on the digital value. |
