I recently bought a PI camera from Amazon. To my surprise it shipped from China and looks a little bit different than another one I bought locally. The box it came in was plain white (No Raspberry Foundation writing/logo on it). This leads me to believe it might be a fake. Anyone knows how to tell a...

Re: Sense Hat NOT detected any more

Here is one more hint. I have 2× PI 2 B. One SD card has the NOOBS package, the other has a Matlab installation. It appears the Matlab installation is preventing the PI2 from detecting the SenseHat. I did swap the SDs between the 2 RPIs, and now, the SenseHat works fine. Thus, I now know for sure th...

Sense Hat NOT detected any more

I managed to get it working fine and was able to run some sample codes. Now however, whatever program I run, I get an error message telling me OSError: Cannot detect RPI-Sense FBdevice The other thing I noticed is, when it was working, the 8x8 LED display would light up at boot-up, then turn off aft...
