lp smart board siding

lp smart board siding.By rearranging the formula into the form of C = (I ?? T) / V, the relative change in capacitance can be detected by observing the voltage change. According to the previous formula, the following steps are involved in detecting the touch process: connecting a capacitive touch sensor (as a capacitor) to a channel multiplexed with the CTMU peripheral and the ADC; initially, a constant current source The touch sensor is charged for a fixed period of time (T), and the voltage (V) on the sensor is measured by the ADC, as shown in FIG. 3; as long as the capacitance due to the touch sensor pad does not change, The voltage does not change during the continuous measurement of the charge multiple times.
