DLPU018J October 2014 – June 2024 DLPC900
This chapter lists the DLPC900 control commands.
The following sections list the supported control commands of the DLPC900. In the Type column, ‘wr’ type is a writable field through I2C or USB write transactions. Data can also be read through I2C or USB read transactions for ‘wr’ type bits. Type r is read-only. Write transactions to read-only fields are ignored.
The Reset column in all of the following command tables is the default value after power up. These values may be overwritten after power up.
Reserved bits and registers. When writing to valid command bit fields, set all bits marked as unused or reserved to 0, unless specified otherwise.
Momentary Image Corruption During Command Writes. Certain commands may cause brief visual artifacts in the display image under some circumstances. Command data values may always be read without impacting displayed image. To avoid momentary image corruption due to a command, disable the LEDs prior to the command write, then re-enable the LEDs after all commands have been issued.
Writing or reading from undocumented registers is NOT recommended.
