Figure 10. “?” command

Every command is composed of two parts: the command prefix (normally two characters)

and the command fields. Any incorrect typed character can be changed using the

backspace character.

Each LED channel is identified by the channel (ch) number only (from 0 to 3).

7.4

Commands

The following section describes the commands accessible through the console.

7.4.1

lc - change LED current

The command is used to change the current in the specific LED chain. The configured value

is stored into the E2PROM data area for its read back and applies to next power-on.

Syntax: lc [ch] [I]

Parameters:



ch [0-3]: the LED string channel value.



I [0-10]: current index as shown in Table 1 on page 14. It represents the peak of the

chain current and the index ranges from 0 (273 mA) to 10 (1184 mA).

Output: none

Example: lc 2 3: configures channel 2 to use 492 mA mean current.
