What you will need is a pixel mapper and rework the multiplexing logic. The Arduino will work with these about as good as it would with any constant current HUB75 based LED Matrix. Naturally these panels use more power and can have less load frequency due to reduced multiplexing.

P10 stands for 10 meters if I am not mistaken.

These are to be used in daylight or far away. P10 and/or outdoor modules are known to do this. Generally speaking the 1/4, 1/2, etc multiplex panels use direct drive and not a 74HC138 decoder. In order for the PCB trace stuff to work they use a goofy pattern. This would lower the number of pixels per panel, so to compensate for this they increase the chain length internally. This means they reduce the multiplexing which results in higher average current. I might have to use say 4 promini modules to split the workload ? Is there a library I could use with just connecting the one colour, and sorting out the 1/4scan driving sequence ? There are other HD controller modules with 1/4 scan HUB75 connectors, with usb drive, but I will still need the Arduino to feed the array to it, and I have no idea of the format. I need no animation, or large font tables, or dimming, and I really wish I had bought single colour panels which I could have driven easily with the DMD library. However, I only have 6 yellow numbers (0-9), 12 green numbers, and 6 red numbers. I can understand that as these displays have to be constantly refreshed ( unlike my previous latched 7 segment ones that were ' light and forget ' ) that memory will be precious. ( P10 32x16 LED panel 1/4 scan now works with Adafruit_GFX)īut reading the Adafruit description and it says that their library is pushing it to drive just one panel with full colour with an arduino memory. I have searched around and found some posts such as:. Of course some of the actual numbers are grouped into 3 or 4 for the new display modules, so I only need 8 panels. I would like to be able to use my existing decoding sketch that has an array of 24 characters to send to the panels. I it is a copy of a previous board I made which had 24 daisy chained 7 segment displays with TPIC6B595 shift register / drivers. My next project has 8 full colour modules, 1/4 scan, with HUB75 sockets. While I had played with the DMD library, this project needed a celphone/wifi update function, so I used the HDW00 controller module and it works fine. My first project used single colour red Leds to display on a 32 x 32 LED panel ( made up of two 16x32 panels stuck together.) I have recently got into using P10 multiplexed LED modules. I hope this is the rightplace on the new forum to ask advice on LED P10 modules.
