Sense HAT rainbow colors latched on power up

Tue Aug 15, 2017 2:37 am

Hello, I purchased a sense HAT to help get my son excited about weather data acquisition but the LEDs stay latched on the rainbow colors. I understand that the LEDs should go clear once the boot process is complete. Please help

Hi there
Okay so if that happens it either means the EEPROM on the Sense HAT isn't working, or the EEPROM ID pins are not connected between the HAT and the Pi. Which happens if you're using a shorter pin header.

The good news is you can override this by adding a line to config.txt. Open a Terminal window and enter the command below:

Code: Select all

sudo nano /boot/config.txt
Scroll to the bottom of the file and append this line:

Code: Select all

dtoverlay=rpi-sense
Now press Ctrl - O, followed by Enter to Save. Then Ctrl - X to quit.

Then type in the command below to reboot:

Code: Select all

sudo reboot
Hopefully that should do it. If this doesn't help it might be that you need to update your SD card to the latest version and then try again.

Will also happen if you forgot to put your SD card in, or accidentally ejected it. ;)
