Addressable RGB LED Strip
Recently I played with something I think is something of a Holy Grail enthusiast circles LED: the addressable RGB LED strip.
Non-addressable RGB band (which means you can turn the whole strip is a particular color, but not a single LED) will be easier to find on the market, but a led strip of RGB, where you can actually control each LED separately were only the fantasy of geek. Whenever I did something publicly with RGB strip joint, has anyone came up to me and said "oh wow man, you can control each of the visionaries?". No, excuse me, with these bands you could not - but with this band you can!
So where are these bands are legendary? Well, I played with one fell on my knees a few months ago - thrown there by my friend Dan who got it from a factory in China looking shady, while evaluating products LED wall video. I asked him the name of the plant, but it was far drawing a blank.
At the time he assumed (as I did when I first saw it) that the band consisted of nothing more RGB LED connected to change the industry standard for files, similar to how I built my own color LED strip series. This is not the case and that the chips to drive the LEDs are actually full of a little intelligence for them.
This became clear when he built a simple test program with respect to the band as a common shift register, but did not work so confusing. Eventually I had to cut some of the silicone liner on the tape to get a closer look at the controller chip. The chip has proven to be a "HL1606", there is nothing that I had never heard of. A few hours of online research left me with a sheet of HL1606 written only in Chinese and one screen with a "Cohn-Jean" in September 2007 for anyone with information on how to drive the chip. The screen does not get useful answers.
I tried to install the version with the Google translator, which was a bit 'of success, but it left me scratching my head to the exact way to interpret sentences like this:
When a data bit on the road 10 (or D2D1 D4D3 D6D5 o) and latches valid, the corresponding status LED output driver slowly changes when the change required to keep the brightest light of the state, to "that new data is entered and effective latch.
* It sounds like English, right? Yes, anyway, trying to decipher the technical lasted only so long before it was captured from the distractions and the largest band of RGB sitting at my desk untouched for months.
Maker Faire then arrived and, fortunately monster while I talk to people about it MonkeyLectric bicycle wheel, a guy came by wearing the most eye-catching banner. The band was built flexible material that RGB LED strip circuit were mounted and were clearly be individually controlled. Obviously, it was a guy I had to talk. After a short conversation, I learned that he had found the band using electronic media in China, was built using the strip HL1606 driver chips, and he also had a devil of a time (and only one partial success) to learn how you can drive. We exchanged contact information and a promise to get in touch after the ability to share data and Geek tape. Only after I got home, I reconstruct this guy was none other than "John Cohn," so lonely, unanswered calls for assistance in 2007 was the only evidence I could find that second in the world someone was playing with these bands.
Pierre Maker Faire.
Anyway, shortly after we arrived at our respective homes, John sent me a copy of these instructions in Chinese, I had already found previously, and the CIP code for the banner. PIC code, was the missing key to the puzzle and the student with the machine translated page I was finally able to get my head wrapped around how the chip worked.
Here is a short video showing an arc base displacement (the "hello world" addressable RGB bands):
