Hello all ! I have a stupid problem. The routeur I use is a Belkin N600 DB f9k1102v1 , running "Tomato Version 1.28 by shibby". I know it's an old version, but it's not my main routeur, and not even sure a more recent Tomato version would run on it Here's my (simple) problem. I plan to use it for electronic experiments. I want to use the buttons status to activate a device I will plug in parallel with the leds. I can activate / desactivate leds with gpio enable/disable, and can also see when I press a button with gpio poll. So the goal is to use an external captor, plug it in // with a button, and activate a relay with a transistor in // with the led. Basic stuff. There's an option with the web interface "Administration -- Buttons/LED", but it doesn't work I'm not sure the firmware I use is for this exact routeur model, and don't remember where I got it root@belkin:/tmp/home/root# gpio poll Enable gpio mask: 0x0000 60F03EAF 0220.127.116.11ABCD.. 60F03EAF 018.104.22.168ABCD.. ....... 60F03EA7 012..5.7.9ABCD.. <--button reset pressed 60F03EAF 022.214.171.124ABCD.. ....... 60F03E2F 0123.5...9ABCD.. <--button wds pressed 60F03EAF 0126.96.36.199ABCD.. ....... I'm not so good for programming, and don't manage to get those changes with a shell script. I've tried without success : - gpio poll | grep 7 --> blank output - gpio poll >> status.log& --> empty file - export STATUS=`gpio poll`&; echo $STATUS --> blank $STATUS What's the trick ? I also couldn't find documentation about /sbin/gpio and /sbin/buttons/ relative to Tomato. Thanks a lot.
