SkyCamOne HAT FAQ – Frequently Asked Questions | |
|---|---|
Installing SkyCamOne HAT software
Go to Software Installation
How can I replace RPi.GPIO (LibGPIO) with Blinka?
Via SSH or directly on the prompt (with screen and keyboard), enter the following lines:
pip3 uninstall -y RPi.GPIO
sudo apt-get install -y i2c-tools libgpiod-dev python3-libgpiod
pip3 install --upgrade adafruit-blinka
You can also choose to run our software installation. See the Software Installation page for details.
How do I connect my 12V power supply?
Connect the positive lead of your 12 volts power supply (usually red) to the left side of the 12V IN terminal, and the negative lead (usually black) to the right side terminal.
My dew heater does not really get hot. It gets a little warm but nothing more
- The dew heater needs a little more power. You probably have the Raspberry Pi powered via USB-C, but have not connected any additional power like the 12 Volts in or the Power over Ethernet (PoE).
Prefereably, do not use the USB-C to power your Raspberry. Your SkyCamOne will provide more than enough power to your Raspberry once you connect either one (12V or PoE) and you will find that the heater works much better! - Did you verify that your dew heater is rated at 5 volts? Many dew heaters are 12 volts devices and will hardly warm up when connected to 5 volts.
If your dew heater is in fact a 12V heater, you can connect it to the 12V OUT terminal, however it will be always on. Consider this a temporary workaround.
When I run sko-fantach.py or sko-fan.py, I get an error "lgpio.error: 'GPIO busy'"
This is because SPI is enabled.
To make sure the correct interfaces are enabled and SPI disabled, do the following;
Via SSH or directly on the prompt (with screen and keyboard), enter the following lines:
sudo raspi-config nonint do_i2c 0
sudo raspi-config nonint do_spi 1
sudo raspi-config nonint do_serial_hw 0
sudo raspi-config nonint do_ssh 0
sudo raspi-config nonint do_camera 0
sudo raspi-config nonint disable_raspi_config_at_boot 0
What software can I use for my all sky camera?
There are multiple “flavours” of all sky software. The two most commonly used flavours are INDI Allsky and TJ Allsky.
The above links lead you to their respective GitHub pages where you can download the software and where you will learn how to install and use it.

Our dew heaters run on 5 Volts and are specifically designed to use with our SkyCamOne HATs.
Connect these with a two-wire cable to the DEW HEATER screw terminal on your SkyCamOne HAT. Polarity is NOT important.
Connecting a 12 volt dew heater to your SkyCamOne HAT will work, but it will not get as hot. |
