Abstract
A multichannel touch controller includes a signal receiving circuit having N electrode pins electrically connected to touch screen for receiving respective sensing signals, switching circuit having N switch sets each consisting of first switch and second switch respectively connected in parallel to the N electrode pins, microcontroller, and processing unit having N analog front-end circuits and analog-to-digital converters with N analog front-end circuits respectively electrically connected to the first switches, the 2analog front-end circuit and the N+1 analog front-end circuits respectively electrically connected to the second switches and the analog-to-digital converters respectively electrically connecting the analog front-end circuits to the microcontroller (MCU) to constitute N+1 channels for processing sensing signals so that when one channel fails, the microcontroller switches off the respective first switch and switches on the respective second switch so as to skip the failed channel until switching of the last electrode pin to the standby channel.
