allpixmatrix

A Processing based video creation and mixing application for low resolution LED screens and matrices. See a video at https://youtu.be/yl-yPLLxuSU

ws2801fet

Based on the WS2801 chipset this 3 channel MOSFET driver allows high current and/or high voltages(5v to 60v) to be controlled just like a standard WS2801 pixel. Great for controlling 12 volt RGB LED strips or other types of high wattage LEDs in various configurations. Operates just like any other pixel, so they can be chained together or controlled by themselves. Easy to interface to from an Arduino, PIC or other logic devices with a SPI port. The control scheme is simple, send 3 bytes of data for every module in the chain using a standard SPI port, waiting at least 500uS between updates. Or they can be controlled with one of the many NLED Pixel Controllers.

live-pixel-mapping-software

Reads a patch/map file created by NLED Patcher to create a coordinate grid. Reads an input serial data stream and uses the map file to re-order the serial data, and send it to an output serial port.

aurora-interface-example

Sample code for interfacing with NLED Controllers and Devices

APA102-Products

A small collection of APA102 pixel based products. APA102 is a form of addressable pixels similar to WS2812B, but with a much higher PWM frequency. The high frequency creates a higher quality light than other chipsets, especially at lower intensities.

pixel-mapping-software

Used to create a coordinate patch file for pixel mapping. Files work with NLED Matrix and NLED Aurora Control, but can be adapted for other programs.

IR-NEC-Encoder-Decoder-Board

Receives a raw modulated or demodulated NEC IR signal and converts it into bytes that are sent out the serial port. The serial baud rate is selectable from two default speeds. The default usage mode transmits out a command sequence with framing bytes, address high, address low, and the validated command byte. This device is designed to remove the work load of protocol decoding from the main processor, which could be a PIC, Arduino, FTDI, or other similar serial capable device. It supports full duplex communication when using an I.R. transceiver.

dmx-isolation-v1a

This simple device offers full electrical isolation for differential signals, such as DMX or RS485. Based on the venerable SN75176 transciever with a dual digital isolator and 1:1 DC-DC transformer. The device accepts a TTL input signal when setup to transmit and outputs a TTL signal when setup to receive. The differential conversion is handled by the transciever. Accepts voltages from 5 to 12 volts, but always outputs TTL(0 to 5 volt) signals. This device works with many NLED products and controllers, but would also work with any Arduino or other embedded device as it communciates with standard TTL signals. For details on electrical isolation specifications, please use the BOM to look up part datasheets for details.

nled-configuration-software

A stand alone application for adjusting the configuration options of NLED controllers and devices. Written for Processing 3.

pixelpowerinjectionboard

A passive device that allows a pixel string to be 'injected' with power from a 2.1x5.5mm barrel jack or with screw terminals. This does not do anything to the data signal other than pass it thru.

nled-dual-level-shifter

This dual channel level translator(shifter) is used to convert 3.3 volt signals to 5 volt signals. It features on-board low drop out linear regulators for both the 5 volt and 3.3 volt rails. That allows it to support a VIN of up to 12 volts, which makes it easy to connect to other devices. The TXS0102 I.C. allows speeds up to 24Mbps, designed specifically for addressable LED pixels which utilize clock and data lines, or other types of SPI based communication. The layout of the board allows it to be used inline with standard wiring for adressable pixels, no tricky wiring or jumping.
