We are trying to put an embedded device which can drive a 4.3" LCD with a capacitive touch overlay. Looking at the STM32F439 discovery platform, I see there is a 5.7" LCD with a capacitive touch overlay. We would like to use this platform and be able to swap in a 4.3" LCD. Eventually, we would like our production platform to be built based on this eval board and so I looked through the schematics and the BOM, however there is no mention of the touch controller used. I see references to a touch controller but no controller specifically. How is capacitive touch implemented on the STM32F439 discovery evaluation board.
