3.4 LCD Interface Header

Header J9 contains all of the signals for the internal LCD controller in the MSP432E411Y to interface with an external LCD panel, including four additional GPIO pins. The four additional GPIO pins can be used as analog inputs to interface with a resistive touch screen. Alternatively, two of the pins (PE6 and PE7) can be configured as I2C pins to interface with controllers that require an I2C interface. Figure 7 shows the location of J9, and Table 5 lists the pinout of J9.

NOTE

On MSP432E411Y-BGAEVM Rev A boards, LCDDATA22 is not available on the J9 header. If a connection for LCDDATA22 is required, make the connection to J5 pin 19 (MSP432E411Y pin PS2).
