Table 19-90 Illumination Enable [Opcode: 80h | Destination: 4]
Set Illumination Enable
Write Parameter(s)
Byte Description
Byte 0

0 - Disabled

1 - Only Red LED Enabled

2 - Only Green LED Enabled

3 - Red and Green LEDs Enabled

4 - Only Blue LED Enabled

5 - Red and Blue LEDs Enabled

Table 19-91 DLPA3005 Illumination Current [Opcode: 84h | Destination: 4]
Set DLPA3005 Illumination Current
Write Parameter(s)
Byte Description
Bytes 0-1

Drive Level Red

Bytes 2-3

Drive Level Green

Bytes 4-5

Drive Level Blue

Sets DLPA3005 Drive Current Levels input as 10-bit Drive Level per LED in the range 0 - 874 (actual range is 0-1023 but the value is limited to reduce the changes of damaging reference LEDs). Command should not be used if Dynamic Black or White Point Correction is enabled.

Current output in Amps is calculated as described below.

OutputCurrent = ((DriveLevel + 1)/1024)*((0.15/0.004)) Amps

Example : For DriveLevel = 874; OutputCurrent = 32.04345703Amps

Note: Calculation is based on a max drive of 32A using 4mOhm RLIM resistor, refer to DLPA3005 datasheet to optimize for the LED being driven.

Get DLPA3005 Illumination Current
Data returned is in the same format as the Write Parameter(s).

Gets DLPA3005 Drive Current Levels.
