Hi all,
I am after some help to get some led panels running that were donated to the Norwich & London Hackspaces. About 50 were donated by someone who worked for a large screen installation company and these panels were out of colour spec so were to be binned.
Everything we currently know about them is here:
https://wiki.london.hackspace.org.uk/view/LED_tiles
I & another member have got the Smart shield and the panel does light some LEDs. The pin outs match and I can set a background in the colours I choose. However because the dimensions and I guess arrangement of sub sections, the display is garbled.
I have taken the FeatureDemo example and stripped it down so that it sets the right pixel width & height and the background red:
...
const uint8_t kMatrixWidth = 48;
const uint8_t kMatrixHeight = 36;
...
const rgb24 defaultBackgroundColor = {0x40, 0, 0};
void loop() {
backgroundLayer.fillScreen(defaultBackgroundColor);
backgroundLayer.swapBuffers();
}
I feel the panel is trying to tell me something and someone who is more familiar with the code and these panels maybe able to help. If you can then please let me know.
thanks
toby (+ lots of others)
