h1. Overview 

!hyperholo.png! 

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.

Fig 2: D4100 Controller Configuration Jumpers, Switch and LED

*LED1 - USB status*

*LED2 - APPSFPGA status*

(FPGA PIN N14) 

|_.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(FPGA PIN AK19).

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(FPGA PIN AJ19).

*J2 – EXP Voltage Select*

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

|_.Jumper Position|_.Revision Version|

|close|1|

*J5 – Shared USB signal disabled*

|_.Jumper Position|_.USB Signals|

*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.

*SW1 - Dipswitches*

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

|_.Switch Number|_.Effect|_.FPGA PIN|

|1 |ON = float – float all mirrors|G20|

|2 |ON = counter halt – stop counter, this will freeze the image on the DMD|G21|

|3 |ON = complement data – causes DDC 4000 to complement all data it receives|F20|

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

to reverse order of row loading, effectively

flipping the image|G22|

|5 |Dictates the type of reset being used LSB ON = 1|H15|

||00 : single block phased reset|

||01 : dual block phased reset|

||10 : global reset|

||11 : quad block phased reset|

|7 |ON = Row Address Mode|H12|

|8 |ON = WDT Enable, disables other resets|J14|

*SW2 - Push Button Momentary Switch*

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

(FPGA PIN T24)

*SW3 - Push Button Momentary Switch*

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

(FPGA PIN P10)

*SW4 - POWER STANDBY*

h1. Power Down

*%{background:yellow}To ensure long term reliability of the DMD, a shutdown procedure must be executed.%*

Prior to power removal, assert the PWR_FLOAT (Table 1) signal and allow approximately 300μs for the procedure to

complete. This procedure will assure the mirrors are in a flat state. For more details, please refer to the

appropriate DMD document.

h1. APPSFPGA 

The APPSFPGA contains the Applications FPGA Sample Code for the DDC4100. This sample code

cycles through test patterns and is meant to offer an example of code that meets the DDC4100

specification. It has been written to implement all features of the DDC4100, such as the complement

function and all mirror reset types, as explained in later sections. This sample code also addresses

additional operational requirements for the DDC4100 interface which should be observed.

h1. USB

The USB EEPROM does not have any code only VID/PID data.  Here is a sequence of USB initialization:    

    When a board is plugged in by USB the Windows D4100 USB driver sees the unprogrammed TI VID/PID.  (The Windows D4100 USB driver is installed with the Explorer software.)

    Then it loads a program directly into the Cypress USB (not the EEPROM) and runs it.  (This loads the firmware through USB)

    This sets the Cypress VID/PID to show that the part is programmed and allows communication with the Board.

This is only the first part.  To communicate with the DMD a different APPS_FPGA program (D4100_GUI_FPGA.bin) must be loaded that can communicate with the Cypress USB.

When the D4100 Explorer is started it checks to see if D4100_GUI_FPGA.bin is loaded in the FPGA and programs the FPGA if it not.

This program can also be loaded by invoking the DLL function directly from another program (see the API Programmer’s Guide)

Once loaded then the other API DLL functions can be used to load and reset image data. 

*%{background:yellow}If you have one of the ViALUX ALP versions you will need to contact them concerning this since their software uses proprietary communication protocols with the D4100.%*
