h1. Overview 

The DLP® Discovery™ 4100 (D4100) is the latest in a series of spatial light modulation development kits from Texas 

Instruments.  Users of the D4100 Starter Kit have the ability to manipulate visible, ultraviolet and near-infrared light 

with extremely high performance and high resolution. 

 The D4100 offers developers a flexible platform to design products to fit most any application using the proven 

reliability of DLP technology.

*LED1 - USB status*

CY7C68013A_128

*LED2 - APPSFPGA status*

|_.LED|_.Status|

|RED|BAD|

|GREEN|OK|

*LED3 - DDC4000 status*

|_.LED|_.Status|

|RED|BAD|

|GREEN|OK|

*LED9..12 - LED status*

LED9 - DDC_LED0 Status LED for the DDC4000

The LED0 signal is typically connected

to an LED to show that the DLPC410

is operating normally.

The signal is 1 Hz with 50% duty cycle,

otherwise known as the heartbeat

LED10 - DDC_LED1 Status LED for the DDC4000

The LED1 signal is typically connected to an LED

indicator to show the status of system initialization

and the status of the clock circuits. The LED1 signal

is asserted only when system initialization is 

complete and clock circuits are initialized. Logically,

these signals are ANDed together to show an indication

of the health of the system. If the Phase Locked 

Loop (PLL) connected to the data clock and the DMD

clock are functioning correctly after system

initialization, the LED will be illuminated

LED11 - VLED0 This logic is to be defined by the APPSFPGA application. Drive low to turn on the led. Drive high to

turn off the led.

LED12 - VLED1 This logic is to be defined by the APPSFPGA application. Drive low to turn on the led. Drive high to

turn off the led.

*J2 – EXP Voltage Select*

*J4 – Used to select the revision of firmware loaded from the PROM to the APPSFPGA.*

|_.Jumper Position|_.Revision Version|

|open|0|

|close|1|

*J5 – Shared USB signal disabled*

|_.Jumper Position|_.USB Signals|

|0-1|Disconnected from FPGA |

|1-2|Connected to FPGA|

|2-3|Automatically connect USB signals 

     to FPGA when USB is connected to 

     host PC |

*J7 – USB EEPROM Programming Header* 

Used to temporally disconnect the USB EEPROM fromthe device so the device can load its internal 

boot loader rather than any code in the EEPROM. Install J8 for Cypress internal boot loader. 

*J10 – DAD2000 B Output Enable*

Used to enable the outputs for DAD2000 B. This needs to be enabled only if using the 1080p DMD, 

otherwise this can be disabled. 

|_.Jumper Position|_.DAD2000 B Outputs|

|open|Disabled|

|close|Enabled|

*J11 – Used to select the revision of firmware loaded from the PROM to the DDC4100 (FPGA X5VLX30).*

*SW1 - Dipswitches*

Functionality defined by APPSFPGA programming. In default test pattern code:

|._Switch Number|._Effect|

|1 |ON = float – float all mirrors|

|2 |ON = counter halt – stop counter, this will freeze the image on the DMD|

|3 |ON = complement data – causes DDC 4000 to complement all data it receives|

|4 |ON = north/south flip – causes the DDC 4000

to reverse order of row loading, effectively

flipping the image|

|6 |Dictates the type of reset being used MSB ON = 1|

|5 |Dictates the type of reset being used LSB ON = 1|

||00 : single block phased reset|

||01 : dual block phased reset|

||10 : global reset|

||11 : quad block phased reset|

|7 |ON = Row Address Mode|

|8 |ON = WDT Enable, disables other resets|

*SW2 - Push Button Momentary Switch*

Functionality defined by APPSFPGA. This switch is used for *APPS_LOGIC_RESET* in the default code.

*SW3 - Push Button Momentary Switch*

Functionality defined by APPSFPGA. This switch is used for *APPS_LOGIC_MIRROR_FLOAT* in the default code.

*SW4 - POWER STANDBY*
