2811 Pixels really cheap but need support from pixel controllers.

[fasteddy]

If the protocols are so close it probably wouldn't take much for Ed to tweak the 1804 to 2811, my 2811 strips should be here in the next couple of days so i'll see how well they perform with my p12r's

How many strips of the 2811 did you get, i would love to see how this performs with 2 or 3 strips connected together. The more testing the better.

I ordered 5 lots, Ray must have had them in stock as he sent them the same day I made the order. Will give em a good work out if the 1804 protocol works otherwise will have to wait till Ed adds it (if he intends to).

Here is some info from Jim regarding his implementation of the 2811 using the 1804 protocol with the E68x taken from DIYC thread regarding 2811

There was a lot of confusion regarding the timing of the 1804s, with several different data sheets giving different numbers. The 1804s worked over a range of about 600kbps to about 850kbps. I picked a value near the middle of this range, I think about 700kbps. As it turns out, this is just a hair too slow for the WS2811s. So now my timing is set right at 800kbps, and that value works for the WS2811s and the 1804s.

Has anyone come across any of these pixels that are configured for the 'slow' mode?

Heres a quick question as this cheap of a pixel will make its way on to every part of my house and thus will be replacing on what I was going to have just DUMB RGB strips. Anyone know the usuable distance to first pixel?

jsys "make it so" please

Ray sent through a price list of his 2811 products, so thought I'd upload them here. Couldn't upload the original .xls so converted to PDF

I just ordered a dozen strings.
When thy come in, I'll run them on a P12R and compare with the 2801s I already have

Jim has just given a detailed explanation why the 2811 works with the 1804 and viseversa and what are the pros and cons, so looks extremly positive for using the 2811

I'm totally going to build a massive matrix with 32ICS - 2811 strips.

hmmm 40M of tube for around $300, that sounds like a price that will allow me to put strip around my patio windows.
I need either 1.2M or 1.4M sections so what the best option for constructing this, ip68 strip would be best but that's a lot of cutting that will need to be done and re-sealing.
or I could use 4x 5M and then cutup 20M into 8x 1.2M lengths

Im in the same boat. Its too cheap not to.

Firmware to upgrade the E68x controllers in on the web site now. Current version is an .eeprom file that has to be loaded by a Parallax prop plug programmer. I will post the utility soon that will allow you to send the .eeprom file to the E68x using the lan connection, no programmer required.

In addiiton to support for the WS2811s, new pixel types include the 9813s and the 8806. This version also has the dithering feature that gives 8-bit dimming capability to the 6803 pixels.

The last lot of 2803 strips i got, i got ray to supply in 1.5m lengths with connectors on each end. I am sure he could organise custom lengths of the 2811

This is in an e-mail I got from Jim, after asking about the 2811 support for the e-681:

"Hello Sully,

Well it sounds like I need to update the web site. I made a timing change
to the code for the 1804 pixels, and now that pixel selection will work
for the 2811s also. The new firmware (2.025) is shipping with new E681
orders, and will be available for download to update existing units.

So you should be good to go."
