Re: Split screen marquee/scroll

I have my 192x16 (6 panels) array going at last, I tried the Split/Scroll on two panels and it seems to work OK. 6 Panels is a hungry beast of a thing, even with a good 5V-10A supply and another cheap version 5V-10A supply (actually compared to the better one, it seems more like 5A or 6A) I'm still ...

Re: LEDs and Resistors and Power and USB Ports and Stuff.

I have seen instances where people have blown their USB Port, not using Arduino but other things. And know a guy who's WIN 10 laptop just shuts down the port completely and growls at him with onscreen prompts. If you are running a Laptop with a flat battery (charging) watching a video etc, and then ...

LEDs and Resistors and Power and USB Ports and Stuff.

LED's wonderful things aren't they, say Yes ! Some LED history, skip if you want. In Australia, way back, when domestic LED's first became available for consumer use they were often weird and wonderful shapes and designs. There were no 3mm or 5mm standard resin types as we now know them to be, they ...

Re: Split screen marquee/scroll

It's OK, solved. For some reason "Find" in Notepad didn't do it's job, maybe I typed it wrong, but I don't think so, tried bool first then boolean ? I pasted it into the IDE this time so it was formatted and easier to read. I had a couple of DMD-Master versions, one dated, 4-2012, 24kb, the other, 1...

Re: How to connect 16x32 LED display

The diagram shows where the pins connect to the Arduino, e.g. OE to Digital pin 9, A to Digital pin 6, B to Digital pin 7, etc. It just left out that pins 5, 7, 9, 13 and 15 are also GND the same as pin 3. Just join them all together. Pins 6, 14 and 16 are not used or needed. They are for a Mono Col...

Re: Split screen marquee/scroll

Hi there, My first post here, and very new to Arduino also. As a first project I've picked the DMD display to go with and so far so good, I've got it running a message and can also input Serial via Bluetooth and an Android App. Something I found on hackster.io I think. Though I'd like to add some ch...
