uDMX 1.2 released
7 janvier 2007 | Research
Probably the smallest USB-DMX Interface in the worldThe uDMX is built around an inexpensive Atmel Atmega8 Microprocessor, using only very few external parts, thanks to the excellent firmware-only USB driver from obdev.at.We managed to cram it all into a Neutrik XLR Connector.This is the version 1.2 documentation.See the uDMX Homepage for the whole story and updates…
- very small: as small as it can possibly get
- very fast: uDMX transfers only the minimum DXM channels for your application. If you transmit channels 6-12 for example, uDMX will send channels 0-12 only, giving shorter packets = faster transmission.
- very free: built using low cost components, design and software is open source
New in version 1.2
- Bootloader support: update uDMX firmware over USB, no need for a programmer.
- Two status leds (green and yellow).
- There are two versions of the circuit in the download: A “big” one that you can possibly build on your own, as well as a very tiny one that fits into a standard female Neutrik XLR connector.
If you don’t want to build your own uDMX, you can purchase fully assembled units from us.
- We haven’t tested uDMX with low cost fixtures yet. Maybe the transmission speed is too high for fixtures that don’t follow the DMX standard precisely. We might need to add a low-speed mode.
- Windows driver needs a windows programmer with a windows box
- External object for PureData is planned…
udmx_1_2.tar.gz (315kB) includes the original Eagle-Light files for schematics and board layout, the firmware and bootloader, and a handy external for MAX/MSP (Mac only, for the moment. We’d love to get some help from someone with a Windows box out there…)
