User interface

The user can interact with the STLUX385A device using one of the following commands

displayed in Figure 20:

Figure 20. Command list

The command list can be displayed using the “?” command.

Commands may require several parameters and the user shall use the correct syntax. Any

incorrectly typed character can be modified using the backspace character.

Figure 20: Command list

describes the commands accessible through the console. For

convenience, the resonant stage is referred to as HB (“Half Bridge”).

With the exception of the parameters “in” command, all commands are volatile and their

results are defaulted once the board is reset. The “in” command lets the user modify the

startup value for selected parameters. Any new startup value is stored in an EEPROM

memory.

Caution:

The commands guarantee full access to the board configuration. Please take care when

modifying the behavior of the board via commands. An incorrect configuration change may

damage the board.

9.3.1

ll - configure LED output current

Change the LED output current. This command should be used only when the DALI or

0 - 10 V interfaces are not active. The DALI and 0 - 10 V have higher priority over the “ll”

command. The “ll” values are in range from 2 (minimum current) to 4094 (maximum

current). While operating on the STEVAL385LEDPSR demonstration board, the “ll”

parameters should be configured between 539 (minimum current) and 3450 (maximum

current).
