DMX43 Interface

An DMX512 Interface based on the TI MSP430 microcontroller. DMX43 features two DMX In and Output. Connected to the ECP/EPP parallel port the DMX43 is the fastest parallel port interface on the market today. However development of this interface has halted in autumn of 2002.

Hardware

The current firmware only features 1 output universe.

However, you can look at the current schematic.

Software

DMX43 1.0 includes the firmware, schematics and development docs (currently in german) for the DMX43 interface. You will need the ASL (see below) to assemble the firmware and optionally the bslsh (see below) to upload the firmware.

The firmware of the DMX43 interface is MSP430 assembler, which should be compiled with the latest release of the ASL assembler.

To upload the firmware you can use our BSL shell which should run on any decent UN*X.

Misc

While developing the DMX43 we have gathered some experience with the MSP430 processor, which we decided to share with the community. Read our MSP430 notes to avoid some pitfalls.

The DMX43 Interface was used in a project at the University of Applied Sciences in Hamburg / Germany lead by Prof. Gunter Klemke. We have made some Photos at the last day when we finally put all parts together.
