2.1 LCD EVM Interface Header

The KDK350ADPTR-EVM uses header J1 on the bottom of the EVM to connect to a microcontroller or LCD driver. Table 1 lists the pinout for J1. All of the signals are on the K350QVG LCD except for the backlight PWM signal on pin 32. Table 2 lists the connections between the LCD at J2 and J1.
