Tips

  • sudo raspi-config

  • select Interface Options

  • select Legacy Camera Enable/Disable legacy camera support

  • Reboot and run meteotuxpi

• Remember to enable camera interface . From command line run raspi-config

sudo raspi-config and check under interfaces that camera is enabled

• Remember to disable Raspberry PI camera LED! You can do it adding the following text to /boot/config.txt file .

disable_camera_led=1

You can use normal text editor or command line you can do this with commands

sudo su

echo "disable_camera_led=1" >> /boot/config.txt

sudo reboot

• If you don't get any images check your camera cable connectors and use raspistill to verify your camera is ok with command

raspistill -o test.jpg

• If user receive errors like 'mmalipc: mmal_vc_init_fd: failed to initialise vchiq', allow user to access camera with command

sudo usermod -aG video USERNAME

mmal: mmal_vc_component_enable: failed to enable component: ENOSPC

mmal: mmal_vc_port_enable: failed to enable port vc.ril.camera:out:1(RGBA): ENOSPC

• Another reason might be that you got Meteotux PI running in the background

Check that with command

if it is running use following command to stop it
