Pure data external for the Helios Laser DAC
========================
NOTE: This project is a fork of pd_helios, that provides some extra functionality over the original:
- Access to more DAC features: start immediately, don't block, single mode etc.
- Frame dump - sets a trigger which causes the next frame sent to the DAC to be dumped to the Pd console.
- Adjustable polling limit so that infinite loops are not possible.
- Dynamically change PPS without having to reset the pd_helios object.
- Transforms - scale, rotate, translate, flip.
- Color - TTL threshold, color timing offset, channel mapping.
- Raw mode - disables the builtin points optimization - for when you want to manage subdivision, dwell points etc yourself.
- Geometric correction - scale X Y, shear, keystone, linearity, bow, pincushion
You can use helios-control to adjust all of the above from within Pd.
========================
0.1
note - it's not presently possible to have more than 1 helios object open.
pd_helios currently builds on MacOS, tested on Mojave (OSX v10.14). It builds on Ubuntu 16.04 x64 but I haven't got it to work - using a VM, don't know if this is the issue. It should work on Microsoft Windows with the appropriate libusb library.
Clone this repo and the source code to pure data
git clone [email protected]:timredfern/pd_helios.git
git clone https://github.com/pure-data/pure-data
cd pd_helios
make PDINCLUDEDIR=../pure-data/src/
(or wherever you cloned pure data)
To test the example patch:
pd help-helios.pd
(from wherever you have installed Pd. For the Purr-data distribution of Pd, I used this:)
/Applications/Pd-l2ork.app/Contents/MacOS/nwjs help-helios.pd
Install libusb from Homebrew
First follow these instructions: https://brew.sh/
Then:
brew install libusb
