LED control

[taetae]

guys you can not create a web interface for management of the LEDs and the power of the fan on and ???

Hi taetae,

We need to standardize the LED commands (I already posted about it) and then the setup menu will be able to handle the LED.
But currently, this stays on the todo list...
(if I remember well I asked you to test some commands).

About fan control, the standard settings seems enough. :scratch

sorry, i have been out for holidays a couple of weeks. I have to re-read last posts and i will be updated and ready.

/proc/resoure-dump is not used on the 5big1

the leds defintions can be found in

Code: Select all

/devices/platform/leds-gpio/leds/

these leds are defined in the kernel
"net5big:blink:front",
"net5big:red:front",
"net5big:blue:front",
"net5big:red:sata0",
"net5big:red:sata1",
"net5big:red:sata2",
"net5big:red:sata3",
"net5big:red:sata4",

each entry will have some files, one of them will be brightness
the leds can be controlled by sending 0 or a value uptil 255 to this file
for instance doing this should switch off the blue led on the front side

Code: Select all

echo 0 > /devices/platform/leds-gpio/leds/net5big:blue:front/brightness

I do not find this:

Code: Select all

/devices/platform/leds-gpio/leds/

Hi taetae,

Do you test the command line for the blue front line?

Please, could you describe what is the current behavior of all leds of the 5big1.

I don't remember if you already tried these commands. Can you check if you can export some gpio.
So do this

Code: Select all

 echo 10 > /sys/class/gpio/export
 echo 11 > /sys/class/gpio/export
 echo 13 > /sys/class/gpio/export
 echo 14 > /sys/class/gpio/export
 echo 15 > /sys/class/gpio/export

(note: 12 must not be used)

LEDs front and rear LEDs turn on and off intermittently

Code: Select all

~ # echo 10 > /sys/class/gpio/export
sh: write error: Device or resource busy

Please, taetae read fully my posts...

I asked two other points :
- test command for blue front LED
- describe our current behavior of all LEDs (binking or not,...)

sorry I have now added the comment

[Jocko]

and about this command:

Code: Select all

echo 0 > /devices/platform/leds-gpio/leds/net5big:blue:front/brightness

front blue LED is switch off ?

if yes, test these commands

Code: Select all

echo 1 > /devices/platform/leds-gpio/leds/net5big:blue:front/brightness

front blue LED is switch on ?

Code: Select all

echo 127 > /devices/platform/leds-gpio/leds/net5big:blue:front/brightness

brightness is higher?

Code: Select all

echo 255 > /devices/platform/leds-gpio/leds/net5big:blue:front/brightness

this should the max brightness?

Please list the folder content of

Code: Select all

ls -al /devices/platform/leds-gpio/leds/net5big:blink:front
ls -al /devices/platform/leds-gpio/leds/net5big:blue:front
ls -al /devices/platform/leds-gpio/leds/net5big:red:sata0

[taetae]

nothing changes always turn on and off and the command returns this:

Code: Select all

~ # echo 0 > /devices/platform/leds-gpio/leds/net5big:blue:front/brightness
sh: can't create /devices/platform/leds-gpio/leds/net5big:blue:front/brightness: nonexistent directory
~ #
