Controller PCB

The controller PCB shown in Figure 1-1 includes the DLP5532-Q1 DMD, the DLPC230-Q1 DMD Controller, and the TPS99000-Q1. The controller PCB supports video inputs from either a micro HDMI or OpenLDI interface and provides the formatting and control to display the video on the DLP5532-Q1 DMD. The EVM can be controlled with either a SPI or an I2C interface. The SPI or I2C interface can also be used to reprogram the serial Flash that is used to store DLPC230-Q1 software and configuration. An optional second SPI port is provided for monitoring the TPS99000-Q1. The EVM has an external photodiode input that is used to control white point and brightness over the dimming range. An optional second photodiode input is also provided. The EVM includes a flex interface to control and monitor the illumination driver PCB. It also provides an optional interface for thermistors on the red, green and blue illuminator PCBs that can be used to monitor the temperatures of the illuminators.

The controller PCB switches are listed in Table 1-3. SW4 is a toggle switch for PROJ_ON which is used to turn on and off the electronics. Note that parts of the board are still powered when PROJ_ON is in the off position. SW1, SW2 and SW3 are dip switches that control the states of configuration signals the DLPC230-Q1 reads when it comes out of reset. These switches must be set based on the desired configuration options.
