I'm wondering if anybody has any information on WE826 hardware, specifically GPIO ports and sensors (if any).
To be more specific:
- there are a few LEDs on the board - are they all software controlled? How can I access, for example, the "Internet" LED from the software, which GPIO line?
- does the board have a temperature sensor of any kind? If yes, how it can be accessed from the software?

I have asked the manufacturer for this information.

There is no temperature sensor on the PCB.

All LED lights are controlled by software.

This is the contents of a document sent by the manufacturer:

Code: Select all

thank you, Jim

I'll try to work with GPIO#40

Numbering is weird... This is what I see on my system:

Code: Select all

# gpiodetect 
gpiochip0 [10000600.gpio] (24 lines)
gpiochip1 [10000638.gpio] (16 lines)
gpiochip2 [10000688.gpio] (1 lines)

and here are the current assignments:

Code: Select all

# gpioinfo 
gpiochip0 - 24 lines:
	line   0:      unnamed       unused   input  active-high 
	line   1:      unnamed      "reset"   input  active-high [used]

	line  15:      unnamed "zbt-we826:green:usb" output active-high [used]
gpiochip2 - 1 lines:
	line   0:      unnamed "zbt-we826:green:wifi" output active-low [used]

So, WAN and LAN port LEDs are not visible and I cannot guess which one is #40.

jfrog, did you get the list of gpio lines by using this command?

echo N > /sys/class/gpio/export

I ordered a WE826 and should be receiving it soon. I was hoping to be able to power toggle the WE826's USB port, but reviewing the supported ROOter routers indicates the WE826 doesn't appear to support USB port power toggling. Based on jfrog's dump of the WE826's current assignments, line 15 of gpiochip1 appears to allow interaction with the USB LED, but what about the actual USB port?

Do the unnamed and unused lines have any control over other parts of the WE826's board? If there's control over the USB port, I'm hoping to use commands such as:

ON
root@OpenWrt:/# echo 1 >/sys/class/gpio/gpiochip1/15

OFF
root@OpenWrt:/# echo 0 >/sys/class/gpio/gpiochip1/15

This is the exact kind of info I have been searching for. Completely new to these routers and I am using the WG8526. Looking to try and get three of the LED's working for 2.4 and 5 Ghz wireless and the third one for 3g/4g to be on when the 7565 is connected.

This thread is the only info I have been able to find.
