DLPU114A August 2024 – November 2024 DLPC8445
This section describes the command protocol implemented for DLPC8445 and DLPC8445V. This is the protocol to be used by the application processor to control DLPC8445 and DLPC8445V using any of the supported commands. This protocol is applicable across all supported peripheral interfaces.
This protocol specifies a flexible length header. The minimum header length is one byte. The first header byte indicates how to interpret the remaining bytes such as opcode, data, and checksum (for error detection). There is also a destination parameter in the header that directs the command to different entities within the projector application.
Use this flexible header length method for application that require a minimum of overhead bytes can opt for the one-byte header. For a more robust application, configure a larger header that includes data length and/or checksum.
