Tool/software: Linux
Hi all,
I am new in the led field.
I am trying to control the lp5562 led via i2c.
But after I set the value in the register(like pwm), the led didn't do anything.
I also tried to set other value of register, but it doesn't work.
Is there any example command to set the led? (just let RGB all light on or off)
Or any keyword help me find the answer.
By the way.
I have try the echo method (like: echo 2 > /sys/bus/i2c/devices/2-0030/select_engine )
But "select_engine" or other symbol didn't found in the devices/xxxxx/ folder.
Is this means the led chip doesn't work?
Thx,
Peter
