Install script is missing a of dependencies and simply does not work

[Kareltje1980]

Board: RPI4 4GB Distributor ID: Raspbian Description: Raspbian GNU/Linux 10 (buster) Release: 10 Codename: buster

Fresh install, including an apt update and apt upgrade. git cloned the repository and performed ./install.sh as per tutorial

All fine up till now.

But then when trying to run all-in-one-no-pm.py

Error 1

Traceback (most recent call last):
  File "all-in-one-no-pm.py", line 7, in <module>
    import ST7735
ImportError: No module named ST7735

fixed using: pip install ST7735

Error 2

Traceback (most recent call last):
  File "all-in-one-no-pm.py", line 13, in <module>
    import ltr559
ImportError: No module named ltr559

fixed using: pip install ltr559

Error 3

Traceback (most recent call last):
  File "all-in-one-no-pm.py", line 11, in <module>
    ltr559 = LTR559()
  File "/home/pi/.local/lib/python2.7/site-packages/ltr559/__init__.py", line 212, in __init__
    BitField('ALS', 0x0F)
  File "/home/pi/.local/lib/python2.7/site-packages/i2cdevice/__init__.py", line 166, in __init__
    self._i2c = smbus.SMBus(1)
IOError: [Errno 2] No such file or directory

And I am out of ideas at this point...

The installer now only installs for python3. You should run examples with Python 3.

Failing to set up the i2s bus is an issue, though, the script should be doing that. Did you see any error output when running the installer? What's the content of your /boot/config.txt

[Gadgetoid]

Grab and run check-install.py to verify everything is where it should be - https://github.com/pimoroni/enviroplus-python/blob/master/check-install.py

Run with:

python3 check-install.py

Thanks!! The python3 did the trick. This is the config.txt

# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# Uncomment some or all of these to enable the optional hardware interfaces
dtparam=i2c_arm=on
#dtparam=i2s=on
dtparam=spi=on

# Uncomment this to enable infrared communication.
#dtoverlay=gpio-ir,gpio_pin=17
#dtoverlay=gpio-ir-tx,gpio_pin=18

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

[all]
#dtoverlay=vc4-fkms-v3d
enable_uart=1
dtoverlay=pi3-miniuart-bt
dtoverlay=adau7002-simple

The install script confirms all is working.

Have you?
  • Rebooted after installing
  • Made sure to run examples with "python3"
  • Checked for any errors when running "sudo ./install.sh"
