Hi...the Sense HAT’s EEPROM sets up a framebuffer device at start up for the Matrix, so if you restarted the Pi since you had it working then you need to shut down the Pi and boot again. I guess unplugging and plugging the Sense HAT ‘live’ could damage it. It is certainly good practice to avoid live plugging hardware.

Hi,

What version of Mathematica are you running? You will need 11.0.1 to use the SenseHAT driver. You may need to update your Raspian to use Jessie over Wheezy, which only supports 10.0.2 and doesn't include the SenseHAT. Once you are running under Jessie, you can then update Mathematica with:

sudo apt-get upgrade wolfram-engine

Thanks,

Ian

Thank you for your advise ( two persons ) on my premitive question. Under your advise, I think in deep what is wrong.

1) I am running Mathematica 11.0.1 within latest Jessie. But I put the command for upgrading my Raspbian-Jessie & Wilfram-engine - since I wouldkike to confirm I am using the latest code-libray of Raspbian(Jessie).

2) I confuse that the coding style for both Python3 and Mathematice 11.0.1 are same, but this is BAD coding for Mathematice. On the Mathematice 11.0.1, it should be as below - 1st person show me "right coding on device-control". ------ sensehat= DeviceOpen["SenseHat"]

    DeviceRead[sensehat,"temprature"]

So, I could solve my problem and I leran that I need study more "Mathematica coding" thru the device control of SenseHat.

Again, thak you very much
