Hi, thanks for any help in advance - go easy I`m new to RPi and Linux in general I have seen other people with the exact same problem but have never seen a solution on a forum so far I can turn on the 4 leds and make them flash on the explorerhat, but when I came to set the outputs it wouldn`t work. I quickly realised I needed to do some things first to import explorer hat into python, but whatever instructionsI follow, it seems that I can never find i2c, although it is supposed to be ready. using: sudo i2cdetect -y 1 it just shows a message like Error: Could not open file /dev/i2c-1’ or/dev/i2c/1’: No such file or directory I tried to enable i2c using raspi-config and it appears to work. I have done: curl [get.pimoroni.com/i2c](http://get.pimoroni.com/i2c) | bash sudo apt-get install python-smbus sudo apt-get install python-pip sudo pip install explorerhat everything appears to be ok but trying to imprt explorerhat brings up Traceback (most recent call last): File “”, line 1, in File “/usr/local/lib/python2.7/dist-packages/explorerhat.py”, line 624, in \_cap1208 = captouch.Cap1208() File “/usr/local/lib/python2.7/dist-packages/captouch.py”, line 187, in init self.i2c = SMBus(i2c\_bus) IOError: [Errno 2] No such file or directory I have disabled device tree I think, device-tree= in config.txt I have dtparam=i2c\_arm=on in /etc/modules I have i2c-dev i2c-bcm2708 lsmod shows Module Size Used by i2c\_dev 6027 0 i2c\_bcm2708 4990 0 whatever I do there is never i2c in dev. Sorry for lack of clarity or any ridiculous noob errors, but this is my first day with the RPi I am an absolute beginner. Thanks. G. ---

This is another one of those instances of Raspbian just not wanting to enable I2C that I’ve never managed to diagnose. Have you tried a fresh reinstall of Raspbian to see if it fares any better? It looks like you’ve tried basically everything else, do you see any devices when you: `ls /dev/i2c*` ---

Hi, thanks for the help. ls /dev/i2c\* it say something like cannot access /dev/i2c\*: No such file or directory this is despite everything seeming to work properly up to this point. If I can`t enable i2c, does this restrict me from using all the lovely HATs that are available? I find it strange that I can still make the 4 LEDs on the explorer pro turn on or flash using python without importing explorerhat. I have not tried a fresh install of Raspbian yet no - it was a pre-installed versionon the SD card, should I just download a new copy from somewhere and try that? ---

The LEDs on Explorer Pro are just connected to regular GPIO pins- so they’re easy enough to control without the library itself. Before doing a full reinstall, have you tried also updating your Raspbian card to the latest version? You can do this by running: ```bash sudo apt-get update sudo apt-get upgrade ``` And then rebooting- this will take a while! If all else fails, to reinstall Raspbian grab the image from here: [https://www.raspberrypi.org/downloads/raspbian/](https://www.raspberrypi.org/downloads/raspbian/) And follow the steps here that are relevant to your desktop/laptop operating system: [https://www.raspberrypi.org/documentation/installation/installing-images/README.md](https://www.raspberrypi.org/documentation/installation/installing-images/README.md) ---

Thanks so much for your help, I will try this next chance I get to have a play. ---

Remove the ‘dtparam=’ from config.txt (in other words enable device tree) The dtparam=i2c\_arm=on should then load the i2c-bcm2708 module and enable i2c at boot. To get the /dev/i2c\* entry you will still have to load the i2c-dev module. You already have i2c-dev in /etc/modules. Make sure i2c-dev is **not** in the blacklist (file /etc/modprobe.d/raspi-blacklist.conf). If not loaded, you can still load it manually: ‘sudo modprobe i2c-dev’.
