1. Controlling the brightness of the projector.
2. Controlling the contrast of the projector.
3. Disabling and enabling or sleeping and awakening of the projector.
4. Controlling the projection.
Can you help me with a working solution?

    Hello Sidhartha,

    Welcome to DLP forum and thank you for your interest in DLP technology.  The DLP2000 EVM is based on DLP2000 DMD and DLCP2607 controller. Please review the "DLP2607 Programmer guide".  You can use I2C commands  listed in the programmer guide to implement these feature. Please refer to DLP2000 EVM user guide also for additional details on I2C interface.

    Typically, the contrast ratio  of  projector is defined by  the optical system design and is fixed for a projection system. It can not be changed.

    regards,
