system for applications listed in the above section.

1.2 Kit Contents

The DMD EVMs found in Table 1-1 and DLPC4430EVM are designed to be used in pairs. The DMD EVMs

cannot operated with the Controller EVM, DLPC4430EVM.

The DMD EVMs have a board-mounted connector that mates with to the DLPC4430EVM controller board.

DLPC4430EVM includes all circuitry required to drive the DMD EVM.

The DLPC4430EVM includes one DLPC4430 controller, two DLPA100s which serve as the power management

and motor drivers, and other system circuitry such as the parallel receiver and system fan control.

The DLPC4430EVM can be programmed with any firmware which is available on the DLPC4430 product page.

2 Software

2.1 Connecting the DMD EVM to the DLPC4430EVM

Before connecting a DLP EVM to the DLPC4420AEVM, identify the male connector on the back of the DMD

EVM.

The connectors are keyed by design and must follow an orientation to mate with the female connector (J63)

located on the DLPC4430EVM.

The EVM needs to look like Figure 2-1 after the FMC cables have been properly connected between the

DLP650NEEVM and the DLPC4430EVM. The process is the same for use with the other DMDs seen in .

Figure 2-1. EVMs Connected

2.2 Quick Start

This section details a quick start guide on how to:

• Download the associated software

• Connect a DMD EVM to the DLPC4430EVM

• Power up the DLPC4430EVM

• Program the DLPC4430EVM to display a SPLASH image on the DMD

• Troubleshoot issues

2.2.1 Downloading the Software

Before programming the DLPC4430EVM, make sure the DLPC44xx GUI and DMD firmware have both been

downloaded to the PC. The DLPC44xx GUI allows for operation of the EVM and the DMD firmware is required

according to DMD being utilized. If the DLP650NEEVM is being used, then the DLP650NE firmware is needed.

The DMD firmware and DLPC44xx GUI can be found under the Software Development tab of the product pages

on TI.com. To get started, these are the product pages for the DLP780NE, DLP800RE, DLP470NE, DLP480RE,

DLP550HE, DLP550JE, DLP650LE, DLP650NE, DLP670RE, and the DLPC4430.

2.2.2 Powering-up the DLPC4430EVM and Preparing for the DLPC4430EVM to be Programmed

Before powering up the EVM, make sure the included DLPC4430EVM jumpers are in the correct positions. The

jumper locations are listed in Table 2-1 .

Table 2-1. Reference Designators

Jumper Description (Bold Indicates Default Position)

J9 - Red LED enable or Lamp Ballast Pins 1, 2 connected Red LED Enable

Pins 2,3 connected Lamp Mode

J10 - Daughter Card I2C Clock Pins 1, 2 connected I2C to SCL1

Pins 2,3 connected I2C to SCL0

J11 - Daughter Card I2C Data Pins 1, 2 connected I2C to SDA1

Pins 2,3 connected I2C to SDA0

J12 - Front-end DSP Power Pins 1, 2 connected to 1.8V

Pins 2,3 unused

J13 - Front-end Power Pins 1, 2 connected to 1.1V

Pins 2,3 unused

J21 - Controller Sensor selection Pins 1, 2 connected ADC_SDI

Pins 2,3 connected Comparator Sensor I/F

J29 - Controller Sensor selection (Continued) Pins 1,2 connected ADC_SDO

Pins 2,3 connected Light to Frequency Sensor I/F

J46 - DMD Current Selection Pins 1,2 connected for Low Current DMDs

Pins 2,3 connected for High Current DMDs

Jumper J8 is the Hold BL jumper. This jumper is used to put the DLPC4430EVM into boot loader mode, which

allows the DLPC4430 controllers to be programmed. Connect this jumper to prepare the DLPC4430EVM to be

programmed.

To power up the DLPC4430EVM, a 12 V, 5 A power supply is needed. Make sure the power supply is functional

and the switch SW1 on the EVM is set to off before connecting the power supply to the EVM. Connecting the

power supply when the switch is in the off position can prevent damage to the DLPC4430EVM from poor power

connections. The figure below shows SW1 in the on position.

Figure 2-2. ON/OFF Switch

Once the power supply has been connected to the DLPC4430EVM, the switch SW1 can be flipped to the “on”

position. The user can then plug in the USB cable into the board to prepare for programming the board.

2.2.3 Programming the DLPC4430EVM and Displaying a SPLASH Image

Follow these steps to download and configure the DLPC44xx GUI:

1. Download and install the associated Firmware SW package. The Projector Control (.projector) and Firmware

binary (.img) files are located in the install directory. The same procedure applies to the other supported

DMDs within the appropriate firmware install directory.

2. Setting up Communication Preferences:

a. DLPC44xx GUI supports USB and I2C communication. To change these settings, please go to Edit-

>Preferences->Communication.

Figure 2-3. DeVaSys Communication Configuration

b. For USB, select the USB interface.

Note

USB is the preferred method to download the firmware flash image to the projector as USB is

much faster than I2C.
