14.5.5 CMD_ GetBlendMapGainValues [Command ID: 0x2B]

This command is used to get the gain values set by CMD_ SetBlendMapGainValues. Select the same color channel select option that was used in CMD_ SetBlendMapGainValues and pass the index and number of values to get.

If compressed values were set, then this command returns compressed values. If uncompressed values were set, this command returns uncompressed values.

Table 14-4 Example CMD_ GetBlendMapGainValues Command Packet
Byte Index Value Description
0 0x54 Command packet header (destination 4 ,length present, response required)
1 0x2B Command opcode
2 0x00 Broadcast selected in color channel select
3-4 0x0000 Start index = 0
5-6 0x0040 Number of values to be read. This example reads 64 values.
