Ampire AM-800480STMQW-TA1 part integrates resistive touch too. This is directly connected to BoraEVB's J25 connector. Resistive touch is managed by Texas Instruments TSC2003 controller (U27).
Schematics of adapter board can be downloaded from this [httphttps://www.dave.eu/system/files/area-riservata/BORA_LCD_ADAPTOR_ADBL7000C1R_1.0.0_0.pdf link].

(*) This signal is used to control backlight. It is usually driven by a PWM signal whose duty cycle is proportional to backlight intensity. For the sake of simplicity, in this project this signal is driven by a GPIO, thus only two intensity levels are supported (0% and 100%).

For the sake of simplicity, in this project this signal is driven by a GPIO, thus only two intensity levels are supported (0% and 100%). This is a CMOS 2.5V level signal. Make sure that voltage levels of this signal are compatible with LCD backlight input.
To enable frame buffer driver user needs to:
* for Bora get the pre-built binaries [httphttps://www.dave.eu/system/files/area-riservata/AN-BELK-004-bora-sw.zip here].* for BoraX get the pre-built binaries [httphttps://www.dave.eu/system/files/area-riservata/AN-BELK-004-borax-sw.zip here]
Kernel and device tree can also be built with the following procedure:
