An update on driving RGB, RGBW and RGBWI pixels with Vixen. Attached is a scope photo of some of the signals. The yellow goes up when DMX512A start of frame is found and down when it's done 513 bytes. The pink is the RS485 DMX512A at 250 kbps. I'm using 262 slots of the 512 The blue is the NRZ...

This turned out to be more difficult than I thought. Detailed technical description follows useful for anyone writing their own micro-processor code. The problem is the UCS2912 wants 400nS bits in a pattern of 100 or 110 for a logic 0 or 1. Using the SPI data line to send this out with a...

I finally got the LED tapes that I bought from Ray Wu's store working. http://www.aliexpress.com/item/UCS2912-RGBW-led-pixel-strip-60LEDs-m-DC5V-input-5m-long-non-waterproof-WHITE-PCB/32347877425.html The data sheet for the UCS2912 describes how the RGB pins are addressed within the data...

Ignore this request. I just found what I wanted on Ray Wu's site. He has lots of 4 pin connectors. One set of 5 pin connectors. Is there any sort of standard connector being used for the LED RGB addressable strips? Needed are 5V, CLK, DATA and GROUND so a minimum of 4 pins. Ideally 5 or...

Thank you. I've tried that but it has it's own set of problems. More of an issue in how the sequencer treats the MegaTrees. Even just programming a single row of 50 pixels to do some sort of chase sequence is incredibly tedious so the MegaTree (macro if you will) makes things easier. But...

I have three different types of pixel RGB types. 1. Tape of 5050 RGB LEDs with WS2801 drivers (32 on the tape) 2. GE-35 Christmas light strings RGB+I (1 with 25 lamps, 9 with 50 lamps). These are addressed with addr(6 bits), intensity(8 bits) and RGB (12 bits). 3. On order, two 5m tapes with...

I've built a small module that expects to see data organized in RGB for LED strings, RGB + I for the GE-35 light strings, RGBW for LED strings I've ordered and RGBW+I for lamps used on the 2010 Olympic Rings in Vancouver. So far all I've been able to get VIXEN 3 Megatrees working with the...

I have a couple of LED strips on order that have RGB+W LEDs. I have a number of RGB+W+I where the I is a separate intensity setting for all colours. I've also got a number of GE-35 Christmas strings. http://www.deepdarc.com/2010/11/27/hacking-christmas-lights/ The GE-35's run with wireless...

Thank you. I may have experience at the low level embedded systems but running the show software leaves me somewhat baffled. The Olympic Rings software was written by a friend who unfortunately succumbed to Cancer before we even started the double set of rings. I wrote the PC based...

I have a J1SYS EthConGateway ECG-DR4. I want a few more Ethernet to DMX Universe converters so I started searching. So far I've found http://www.ebay.ca/itm/DMX-512-controller-Art-Net-E1-31-ACN-six-output-input-ports-ArtNet-Ethernet-/321556994192 for $114.50 US and...

After posting today I realized that my first post was way back in October 2011. Then my Christmas lights were shelved and it's all been in a box until now. The reason for getting motivated again is because I was able to pick up a number of the RGBW lamps I designed back in 2009 for the 2010...

Thanks. I had found the first "configuration wiki". Hadn't found the second "updating" which will also be very useful if I can get new firmware. And I have good news. I managed to configure WIN-7 to access the 10.10.10.10 network and after installing jumpers and rebooting I found the...

Edited: Just discovered a posting with similar questions to mine. Sorry for the repetition. Does anyone have a manual for the ECG-DR4 they could send me? Most of the web pages at http://www.j1sys.com/ are dead ends. Granted the home page says we're under construction but the last posting is...

Notice in my original posting the document I quoted on the first line. How a newbie like myself to would know that this document applies since it's a totally different product. Go to the parent folder and click on EthConGateway Documentation and Tutorials and it's empty. Even just a...

After stumbing onto the PIXAD8-Guide-V0.1.pdf I and the WIKI for accessing 10.10.10.10 I was able to finally configure my new DR4. Nice board. Well built. Arrived in a timely manner. Took about 4 hours to find out how to talk to it after lots of searching but only 10 minutes to set it up...
