Here is the pinout assignment to drive the LCD:{| class="wikitable" | | align="center" style="background:#f0f0f0;"|'''LCD Signal'''| align="center" style="background:#f0f0f0;"|'''BORA SOM Signal'''|-| BackLight (*)||IO_0_13|-| LVDS_CLK_P||IO_L13P_T2_MRCC_13|-| LVDS_CLK_N||IO_L13N_T2_MRCC_13|-| LVDS_D0_P||IO_L12P_T1_MRCC_13|-| LVDS_D0_N||IO_L12N_T1_MRCC_13|-| LVDS_D1_P||IO_L14P_T2_SRCC_13|-| LVDS_D1_N||IO_L14N_T2_SRCC_13|-| LVDS_D2_P||IO_L11P_T1_SRCC_13|-| LVDS_D2_N||IO_L11N_T1_SRCC_13|-|} The Vivado project can be downloaded from this '''TBD''' (*) 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%). This is a CMOS 2.5V level signal. Make sure that voltage levels of this signal are compatible with LCD backlight input.
