+ --------------------------------
9
+
10
+ Specify a hardware pattern for the ST1202 LED. The LED controller
11
+ implements 12 low-side current generators with independent dimming
12
+ control. Internal volatile memory allows the user to store up to 8
13
+ different patterns. Each pattern is a particular output configuration
14
+ in terms of PWM duty-cycle and duration (ms).
15
+
16
+ To be compatible with the hardware pattern format, maximum 8 tuples of
17
+ brightness (PWM) and duration must be written to hw_pattern.
18
+
19
+ - Min pattern duration: 22 ms
20
+ - Max pattern duration: 5660 ms
21
+
22
+ The format of the hardware pattern values should be:
23
+ "brightness duration brightness duration ..."
24
+
25
+ /sys/class/leds/<led>/repeat
26
+ ----------------------------
27
+
28
+ Specify a pattern repeat number, which is common for all channels.
29
+ Default is 1; negative numbers and 0 are invalid.
30
+
31
+ This file will always return the originally written repeat number.
32
+
33
+ When the 255 value is written to it, all patterns will repeat
34
+ indefinitely.
You can’t perform that action at this time.
