1 Board Overview
The KDK350ADPTR-EVM provides a physical adapter layer to interface the MSP432E411Y microcontroller (MCU) on the SimpleLink™ Ethernet MSP432E411Y MCU Evaluation Board (MSP432E411Y-BGAEVM) to a Kentec Display K350QVG-V2-F-04 LCD, including the LCD backlight driver. The KDK350ADPTR-EVM can be used as a reference for connecting other LCD modules to the MSP432E411Y-BGAEVM.
The Kentec Display K350QVG-V2-F-04 LCD is a 3.5-inch diagonal, 320-×240-pixel resolution, TFT module display that has LED backlighting and supports the i80 8-, 16-, or 18-bit interface and SPI. The display also includes an integrated resistive touch panel.
Figure 1 shows the KDK350ADPTR-EVM with key features highlighted.
Figure 1. KDK350ADPTR-EVM LCD Evaluation Module 1.1 Using the KDK350ADPTR-EVM
The KDK350ADPTR-EVM is used with the MSP432E411Y-BGAEVM to showcase the 16-bit parallel LCD interface on the MSP432E411Y device. The SimpleLink MSP432E4 Software Development Kit (SDK) includes a graphics library example of the LCD capabilities of the MSP432E411Y MCU.
To use the KDK350ADPTR-EVM with an MSP432E411Y-BGAEVM and the graphics library example, follow these steps:
- Connect the J1 female header on the KDK350ADPTR-EVM to the J9 male header on the MSP432E411Y-BGAEVM. Make sure to align all of the pins. Figure 2 shows how the LCD EVM connects to the BGA EVM.
- Connect a debugger that supports Arm® based MCUs (such as an the XDS110 JTAG Debug Probe) to the PC and to the MSP432E411Y-BGAEVM.
- Apply power to the MSP432E411Y-BGAEVM following the instructions in the MSP432E411Y-BGAEVM User's Guide.
- Import the 'kentec_lcd' example project (/examples/nortos/MSP432E411Y_BGAEVM/grlib/kentec_lcd) into one of the supported IDEs and build the project.
- Download and run the example.

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.

2.2 LCD Backlight Control
The K350QVG-V2-F-04 LCD provides backlighting through six LEDs in a serial configuration which requires 19.2 V at 20 mA for full brightness. The backlight voltage is generated using a TI TPS61042 Switch Boost Converter. The TPS61042 allows PWM control over the backlight to adjust brightness using the Backlight PWM pin on J1 (pin 32). For full brightness, a logic "high" signal is applied to the Backlight PWM pin. For reduced brightness, a PWM signal between 100 Hz and 50 kHz is applied.
2.3 LCD Interface Control
The K350QVG-V2-F-04 LCD supports for multiple interface modes:
- 8-, 9-, 16-, or 18-bit 8080 parallel interface
- 6-, 9-, 16-, or 18-bit RGB interface with 3-wire SPI
- 3-wire SPI
The mode is selected by the PS3, PS2, PS1, and PS0 pins on the LCD. Table 3 lists the selection for each mode. Switch bank S1 on the KDK350ADPTR-EVM controls the PS3, PS2, PS1, and PS0 pins (see Figure 3). The silkscreen adjacent to S1 shows the signal that each switch controls and the position to generate a 1 or a 0. Figure 3 shows the switch configuration to use 8080 16-bit parallel interface.
Table 3. LCD Interface Selection
| PS3 | PS2 | PS1 | PS0 | Interface |
|---|---|---|---|---|
| 0 | 0 | 1 | 0 | 16-bit 8080 parallel interface |
| 0 | 0 | 1 | 1 | 8-bit 8080 parallel interface |
| 0 | 1 | 0 | 0 | 9-bit RGB and 3-wire SPI |
| 0 | 1 | 0 | 1 | 16-bit RGB and 3-wire SPI |
| 0 | 1 | 1 | 0 | 18-bit RGB and 3-wire SPI |
| 0 | 1 | 1 | 1 | 6-bit RGB and 3-wire SPI |
| 1 | 0 | 1 | 0 | 18-bit 8080 parallel interface |
| 1 | 0 | 1 | 1 | 9-bit 8080 parallel interface |
| 1 | 1 | 1 | 0 | 3-wire SPI |
