Periféricos de CTMU para aplicaciones de detección de tocar capacitivas ukaxa phuqasiwa aka fórmula I × T= C × V. uka taypina: I ukaxa constante current fuente de CtMU, T ukaxa fijo periodo de CTMU Cargante capacitiva sensor de táctil, C ukaxa capacitancia de táctil de capacitiva, ukatxa voltaje de citación de la capacita

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, the constant current source charges for the touch sensor Mä fijo periodo de tiempo (T), ukatxa voltaje (V) ukaxa sensor ukanxa ADC tuqiwa uñakipata, kunjamatixa uñacht’ayata; Kunjamatix capacitancia ukax pad sensor táctil ukat jan mayjt’ki ukhaxa, voltaje ukax janiw mayjt’kiti carga ukan continuo medición uka pachanx walja kutiw.

The constant current source present in the CTMU peripheral, combined with a multi-channel ADC, provides an effective platform for interfacing with capacitive touch sensors. Connect the CTMU peripheral directly to the input of the ADC so that it can be connected to any pin via an analog multiple switch.With this configuration, the number of sensors that a single CTMU peripheral can measure will be equal to the number of ADC Canalanakax..
