In need of some help

[orbitbad]

hoping that somebody with more brains than me, can tell me what i'm doing wrong.

got my sense hat on Wednesday (yeah) time to get it working on my pi B+ had for about 4 months loved it

sudo apt-get update
sudo apt-get install sense-hat
sudo pip-3.2 install pillow
sudo reboot

on it all came, lights on like a little rainbow i'm all set....

but on try to run a "Hello World" test it says
OSError: cannot detect RPi-Sense FB device

ok have i done something wrong
just in case got a spare sd card re-down loaded a fresh OS and installed from new...
Still says Cannot detect.
find chat about device tree give that a go.. No joy still nothing
find chat about RTIMULibDrive11 to check from putty and terminal all seems to be working

have checked using their colour_cycle.py code in case i typed wrong always possible but no still comes up with

file "/usr/src/sense-hat/examples/python-sense-hat/colour_cycle.py", line 5, in <module> sense = SenseHat()
file "/usr/lib/python3/dist-packages/sense-hat/sense_hat.py", line 36. in __init__ raise OSError Cannot detectRPi-sense FB device

any help or clues would be great

Code: Select all

sudo apt-get update
(didn't have to do already done) sudo apt-get install sense-hat
(didn't have to do already done) sudo pip-3.2 install pillow
sudo shutdown -h now

installed sense hat
restarted pi, all lights up with rainbow of lights
light stay on.

check Config interfaces SPI and I2C both on.

run RTIMULibDrive11 to check if sense hat getting readings

Code: Select all

pi@raspberrypi ~ $ RTIMULibDrive11

try and run python 3 programs for sense hat

have done all i can think off for the last few days. i need some help.anything received with thanks.

The leds should go out near the end of the boot process.

ls /dev/f*

needs to show a new frame buffer, fb1

Do you have any /boot/overlays running?

For example I use Gert's VGA666 board, & with that enabled, the sense hat will not work, so I comment it out in

/boot/config.txt

#dtoverlay=vga666

when I want to use the sense-hat.

It may help if you post your config.txt contents.

Today's Jessie release of Raspbian contains all necessary software for the sense-hat.

I also find it essential to remove power & reapply it after commenting out the vga overlay, & doing sudo halt.

thanks a lot tvjon

found it after you said where the files where
looked at /boot/config.txt
and then checked /boot/overlay/README.txt found the line for the sense

dtoverlay=rpi-sense

added this into the config file restarted and lights went out near end of boot ran python 3 program and all works fine

thanks for the great help
