Part Number: AM3351

Hi, I am using am3551 processor to display images on LCD of 6.5 inches and it has capacitive touch panel with output as 4 wire. So my query is, does am3351 supports 4 wire capacitive inputs (touch panel). If so, can I directly connect it to the touch interface line of am3351??

    The AM335x touchscreen controller supports only resistive touchscreens. Your display probably has a built-in capacitive touchscreen controller. These usually have an SPI or I2C interface, so you should connect it to one of the SPI or I2C ports of AM335x. You should check your display datasheet for details.
