Installation

Prerequisites

The driver relies on the QHYCCD SDK version 23.09.06 and libusb-1.0.0. The instructions below are for installing from source.

Debian / Ubuntu / Raspberry Pi OS

Install libusb-1.0.0 and build tools
sudo apt-get install -y make cmake build-essential libusb-1.0-0-dev
Install QHYCCD SDK
wget https://www.qhyccd.com/file/repository/publish/SDK/230906/sdk_Arm64_23.09.06.tgz
tar xzvf sdk_Arm64_23.09.06.tgz 
cd sdk_Arm64_23.09.06/
sudo sh install.sh
Clone the repository
git clone https://github.com/ivonnyssen/qhyccd-alpaca.git
cd qhyccd-alpaca
cargo build --release
Run the driver
cd target/release
./qhyccd-alpaca [--help for more info]

Rust version requirements

qhyccd-alpaca works with stable Rust. The minimum required Rust version is 1.75.0.

Missing features

  • LiveMode is not implemented
  • The driver only supports cameras that can transfer 16bit images (almost all cameras can though)
  • FastReadout is implemented using the Control::Speed property in the driver, however this control is not available on any of my cameras, so it is untested.
  • Pulse guiding is not implemented
  • If you find anything else missing or wrong, please open an issue.
