    SPI Controller...has anyone use this before?

    This controller will accept both SPI and DMX according to the specification. But I will try to go with SPI path since I have some experience with SPI but none with DMX. I will be controlling a lot of 5V LED. Each channel will handle up to hundred of LED. The effect will be few groups of light...

    SPI Controller...has anyone use this before?

    Hi thanks for the reply. One thing I am not too clear is about the SPI sequence for this controller. I know SPI signal will work, but how do I figure out what is the sequence I need to send to get it started? Which few bits addresses the channel and which few bits addresses the pixel effect...

    LED with SM16716 IC

    Hi brat, I've used both 16716 and 6803 just few weeks ago. The largest project I did was 1000 of those 6803 in series using a controller with SD card...I think you can easily get one from alibaba...those controller broadcast SPI-like signal. That's what I observed from my oscillator. As for...

    SPI Controller...has anyone use this before?

    Hi, I was looking for some PWM DC Controller and came across this. It works on both DMX and SPI interface. http://ltech.en.alibaba.com/product/447836245-209539754/LED_RGB_pixel_driver_LT_280_24_DMX_channel.html I am planning to use my arduino UNO to act as SPI master. Will it work? I can't...

    24V x 24 Channel Dimmer

    Just curious, does this thing work standalone? Any internal memory?

    Need suggestion on high current PWM

    Hi,[/size]I am in need of a high current multi-channel PWM control board(3A each channel). But need help on which approach to go:First approach:Get a DMX Master Controller(either buy one or build one) and buy those dmx decoder from china manufacturer for a good price...

    RS-232 Weird 8 Relay Controller Help!

    seems like a nice board. Anyway I am just curious about something, is relay meant to be used for high speed switching such as PWM? sorry if it's a silly question since i generally see PWM is used with FET or Transistor.

    LED with SM16716 IC

    Yeah...I was really confused. In the end I ordered the strips of 50 and simply use a 5V DC power supply with sufficient current and they work like charm! It was simpler than I thought.Anyway thanks for all the explanations

    Looking for a multiple channel LED DC Driver

    Yes now I am a lot clearer than few hours ago. One concern is that most of the DMX Controller I see so far can control up to hundreds of channels and they are kinda costly. All I need is to control less than 10 channels. That would be waste of resource if I were going to put the controller to my...

    Looking for a multiple channel LED DC Driver

    Does that mean the controller can operate as standalone unit with the on board memory?(Assuming after I set it with a PC) Thanks.

    Looking for a multiple channel LED DC Driver

    Thanks for the reply. But I am still having a hard time what other boards do I need specifically for this to be achieved. From the wiki I found this :http://www.aliexpress.com/fm-store/701799/209915969-378113147/Easy-DMX-LED-controller-dmx-decoder-driver.html Let's say if I would like this...

    Looking for a multiple channel LED DC Driver

    Thanks for the feedback guys. I'm actually building some LED board which consists of multiple letters (I just want each letter to DIM/ON/OFF) For now I will need 7 channels 12V and probably max 2A for each channel will be sufficient. Yes, a premade PCB with internal memory for sequence setting...

    Looking for a multiple channel LED DC Driver

    Hi Guys, I need suggestion on what is the product for the following specification: -Different channel to control multiple strings of single color LED (i.e. Sting 1=ON, String 2=OFF, String 3=DIM/Half Power) - Able to fully customize timing -DC Input power Something like this: DC Power...

    LED with SM16716 IC

    Thanks for all the reply guys. I am using a separate controller and power supply. As I have never used any chipped LED before, I would like to clarify, in this case I must use a 5V power supply? I only know that normal LED string(chipless), I can use 12V,24V,48V on a string of LED as long as...
