touch screen y display es lo mismo.The implementation method of the eight-wire touch screen is the same as that of the four-wire touch screen, except that one line is added to each bus. For the VREF bus, one wire is used to connect VREF , and the other wire is used as the positive reference input of the digital-to-analog converter of the SAR ADC . For the 0V bus, one wire is used to connect 0V , and the other wire is used as the negative reference input of the digital-to-analog converter of the SAR ADC . Any of the four wires on the unbiased layer can be used to measure the voltage of the voltage divider.
