README
README.mdILDA
This project is a DAC (digital to analog converter) which generates six differential signals based on the ILDA (International Laser Display Association) ISP-DB25 standard. Two signals for the X and Y axis (-10V to +10V), four signals for the channels red, green and blue and one custom colour (0V to +5V). The DAC is controlled via SPI. In this case the software is written for a "Raspberry Pi", but any other controller can be used.
This project contains two sections:
- Hardware: In this section you find a 16bit 6ch DAC for ILDA. Reaching 22kpps (measured with ILDA Test Pattern, theoretical up to 400kpps) limited by the controling "Raspberry Pi". It is resulting in a resolution of 4294967296 positions (~4295 megapixels). The asynchronous LDAC update pin at the DAC, immediately updates the DAC register with the contents of the input register, so all outputs change at the same time and can be synchronised with an external clock.
- Software: C based software to control the ILDA-DAC with a "Raspberry Pi". Supports all Files based on the ILDA Image Data Transfer Format.
Hardware
The hardware is designed with KiCad. "ILDA/hardware/kicad/" Using 5 channels (x,y,r,g,b) with 16bit at 50MHz SPI speed the DAC reaches theoretically 400kpps (50000KHz ÷ (5×24bit) = 416kpps).
Software
Dependencies
Installation
- Install "Wiring Pi". Then follow the instructions on Wiring Pi.
- Download this project to your "Raspberry Pi".
- Change to the "ILDA/software/raspberrypi/" folder.
- Run "make".
Now you can run the software with "sudo ./ildaNode".

Questions
How big is the Ildagenerator PCB?
It measures 75.9 × 54.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ildagenerator use?
94 parts, built around the NMA0509SC, LT1356CN and LTC2656BIFE-L16#PBF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ildagenerator KiCad files?
From the jemtech/ILDA repository on GitHub, at the commit this page was made from: the board is hardware/kicad/ildagenerator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ildagenerator design in my own project?
Its repository states no licence, so its author keeps all rights: ask jemtech before reusing the design.
