![]() ![]() ![]() Of course, we wouldn't leave you with a datasheet and a "good luck!" We have a full wiring diagrams and working Arduino library code with examples from drawing pixels, lines, rectangles, circles and text. The good news is that the display is pre-white balanced with nice uniformity so if you turn on all the LEDs it's not a particularly tinted white. On a 16 MHz arduino, we managed to squeeze 12-bit color (4096 colors) with 40% CPU usage but this display would really shine if driven by any FPGA, CPLD, Propeller, XMOS or other high speed multi-core controller. Instead, you're supposed to redraw the screen over and over to 'manually' PWM the whole thing. Keep in mind that these displays are designed to be driven by FPGAs or other high speed processors: they do not have built in PWM control of any kind. If we happen to get them from the factory we also include 4 mounting screws and mini-magnets (it appears these are often mounted on a magnetic base). Please check out our tutorial for more details!Ĭomes with: a single 32x32 RGB panel, one IDC cable and a power cable. These panels require 13 digital pins (6 bit data, 7 bit control) and a good 5V supply, up to 4A per panel. We suggest our 4A regulated 5V adapter and then connecting a 2.1mm jack. ![]() It requires a high speed processor and more RAM than the Arduino has! These displays are technically 'chainable' - connect one output to the next input - but our Arduino example code does not support this (yet). On the back there is a PCB with a set of dual IDC connectors (one input, one output: in theory you can chain these together) and 12 16-bit latches that allow you to drive the display with a 1:16 scan rate. They have 1024 bright RGB LEDs arranged in a 32x32 grid on the front on a 6mm grid. We thought they looked really cool so we picked up a few boxes of them from a factory. These panels are normally used to make video walls, here in New York we see them on the sides of busses and bus stops, to display animations or short video clips.
