A pin-out diagram can be found on the Proto site. Pin numbers progress counter-clockwise up to 32. Pin number 1 is the one with the dot next to it. Locate the correct pin number on the chip. I do not have such a steady hand or great eyesight. The truth is that it is not insurmountable. At first look, this may seem to be something too difficult to accomplish. There are three places on the ATMega8 where a jumper must be soldered to a pin on the surface-mount chip. I used #10 for ground, #6 for -, and #4 for +.
I cut off one end and connected the XLR connector to the ribbon cable. The USBasp comes with a ten pin ribbon-cable jumper. In addition, a jumper must be added between two pins of the ATMega8 chip to conform with the uDMX circuit. I routed this jumper on the underside of the programing connector. Connections from the chip to ground and 5 volts can be found on the pads labeled C4.Ī jumper connected to the signal output of the ATMega8 chip must be routed from the other side of the circuit board to the data input of the RS485 chip. Check with a continuity tester to make sure there is no connection to ground. A sharp blade similar to an Exacto should work. Traces must be cut on the circuit board in three spots for each pin to break the ground connection. Currently these pins are connected to ground. The + and – output from the driver are jumpered to pins 4 and 6 on the programming connector. All that should be left are pads from the sides to solder to. The pins are bent so they are horizontal and are clipped where the pins narrow. The USBasp is now programmed for uDMX.Īn 8 pin RS485 driver is glued to the underside of the USBasp. From the Command menu select Write FLASH Buffer to Chip. Here choose the uDMX.hex file you have downloaded or compiled. Select Read All and it should upload the fuse and lock bit settings.Īdjust the fuse settings to look like this and select Write All.įrom the File menu select Load FLASH file to Buffer. With the two programmers connected together select Fuses and Lock Bits from the Command menu. This driver can be found on either the USBasp or the Protostack site. This is for Windows and in addition a USB driver must be installed.

The programming software that worked well for me was the Khazama AVR Programmer. Connect the two with the ribbon cable that comes with it. Shorting the two pads labeled R8 will enable reprogramming. If you start with two programmers then one can program the other. The ATMega8 in the USBasp comes flashed with programmer firmware. If it goes well then a uDMX.hex file will be produced.

CD into the directory that contains the source code and type: make all. If it is installed then you can open a command window from the Run menu by typing: cmd.

If you wish to change the source code for different serial numbers or for any other changes you will need to compile. Some downloads will include a precompiled uDMX.hex file. I am using the 1.4 code from the LUTZ site. The anyma uDMX 1.4 source is available from a SVN repository.
The open-source uDMX code is available from different sites. #30 AWG Wire-Wrapping Wire (bigger wire can cause damage) RS485 driver chip $1.00 Here’s just one of a few uDMX is for output only.Ĭan create serial numbers and be reprogrammed The control software might set or retrieve levels directly or might be designed to convert levels sent over Ethernet. USB to DMX interfaces are used by host control software to output or input DMX values.
#Udmx driver download mod
The mod consists of adding a RS485 driver chip to the programmer, routing the signal with some jumpers, and flashing the microcontroller with uDMX code. Both are also based on an open-source USB driver in firmware. The ATMega8 microcontroller chip is the basis for both the USBasp AVR programmer and for the uDMX interface.
This is an inexpensive USB to DMX interface constructed from a modded USBasp programmer.
