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.

(FPGA PIN N14)
|_.LED|_.Status|
|RED|BAD|
|GREEN|OK|
h2. LED3 - DDC4000 status
|_.LED|_.Status|
|RED|BAD|
|GREEN|OK|
h2. LED9..12 - LED status
*LED9* - DDC_LED0 Status LED for the DDC4000
The LED9 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 signalis 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 DMDclock 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).

*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.

h2. SWITCH
*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|

*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.

*Getting Started*
The following steps should be followed in starting board operation using the default APPSFPGA code installed at the
factory :
1.) Connect 5V, 5 A power supply to the supplied power cable. Connect the power cable to J12 with the power
supply OFF.
2.) Confirm all SW2 switches are in the OFF position. Confirm all 5 H1 jumpers are in place. If using a 1080p
DMD confirm J11 is installed.
3.) Connect the DMD to the board with the flex cable(s). One flex cable attached to J13 is used for XGA DMDs,
two flex cables attached to J14 and J14 are used for 1080p DMD.
4.) Turn the power supply ON. D2 and D3 should briefly display red then green to indicate APPSFPGA and
DDC4000 configuration. *D9 should flash green at 1 Hz*. D10 should display green. The DMD will repeatedly
cycle through several test patterns.
*%{background:yellow}To stop operation :
1.) Press SW3 to float the DMD, then turn power OFF.%*

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.%*
