GPIO IR Sensor - Not working
Software
XBian version: Latest XBMC version: Latest Overclock settings: Turbo Hardware Power supply rating: 5V @2A RPi model (model A/B 256mb/512mb): Model B 512MB SD card size and make/type: Transcend 8GB Class 10 SDHC Network (wireless or LAN): LAN Connected devices (TV, USB, network storage, etc.): Powered USB 2 Hub (with USB Flash Drive running the OS), TV via HDMI (older Samsung that does not support CEC), Network drive via Samba share Problem description: I ordered these parts (from adafruit) and tried setting up the sensor/remote with the instructions on the wiki. It tells me to run the following commands via SSH: Terminal xbian@xbian:~# sudo su root@xbian:~# /etc/init.d/lirc stop root@xbian:~# mode2 I've tried different things, such as this post related to Logitech Harmony issues, but still get nothing when I try to run the mode2 command. I tried running (from this thread): Terminal sudo modprobe lirc_rpi sudo kill $(pidof lircd) sudo mode2 -d /dev/lirc0 I ran these commands: Terminal sudo lsmod sudo modprobe lirc_rpi sudo lsmod Terminal Module Size Used by lirc_rpi 4756 3 lirc_dev 6580 1 lirc_rpi I've changed the wires connecting to the IR sensor several times, making sure they are in the correct place. I used a camera to see if the IR remote was working (and it appears so). I am wondering if my sensor is "dead" or if I am doing something wrong (most likely). Is there a way I can know if the IR sensor is working or not? |

RE: GPIO IR Sensor - Not working
No it means the kernel module loaded correctly. If mode2 doesn't output anything when pressing buttons, then your connections are wrong.

RE: GPIO IR Sensor - Not working
Can you connect a led in between the sensor and the RPi to see if it's working?

Re: GPIO IR Sensor - Not working
That doesn't say anything, because it can be an active high or active low sensor.

Try it on the raspberries 5v power output.

Re: GPIO IR Sensor - Not working
I also think the sensor is broken.
