The current will vary somewhat and is dependent on the panel manufacturer and whether they are indoor or outdoor panels. All cabling and power allowances should be made for this level of current however it would be expected that normal usage would be 40% of this figure. The LED panels run off 5V DC and can draw up to 3A per panel depending on various settings within your sequencer and potentially within FPP. It is the HUB75 RGB, 320mm x 160mm, 32 pixel x 16 pixel panel that is commonly used for Christmas display and that is the one that this article mainly covers. Those three interfaces are all 16 pin, but the signals are a little different so are not directly interchangeable. The 32x16 RGB panels are usually a HUB75 (1/8 scan) interface while single/dual colour panels are more likely to use a HUB08 or HUB12 interface. There are single colour, 2 colour and RGB P10 panels with different scan types static, 1/2, 1/4 and 1/8th. The outdoor P10 panels are typically about twice the price of the indoor panels, but they function the same. The outdoor P10 panels have separate red, green and blue LEDs for each pixel and are potted in a sealing compound. The indoor style usually have a single RGB surface mount LED per pixel.

There are also P6, P16, P20, P25, P40, etc, but it is the P10 that is usually used for Christmas displays. Let's see if somebody else has a solution. P10 LED panels are pre-made pixel panels with a 10mm pixel spacing, which is what the 10 in P10 indicates. I can't solve the issues yet but the easy solution is not to spend to much time on this one and go back to using Arduino uno to control the P10 using the DMD library and add a ESP8266 for the wifi communication I can find some mistakes in the implementation, for example in the docs says that AnalogWrite uses goes up to 1023 (16 bits) for the ESP8266 and the library is using only 8 bits (up to 255) (Link 1) without any kind of conversion, I'm not sure about this one but it also seems that the nOE and the sck pins are mixed in the documentation and therefore in the library maybe causing the low brightness, I don't have a oscilloscope to test it. The Library is not fully tested it's a beta version. Tried fixing the PWM frequency (Don't know why I just run out of ideas) and didn't work.ģ.- I have also tried cascading (If that word exists) 3 P10 Displays and I get wrong dots turning on in the second and third Displays, this didn't happen with the DMD library using arduino uno. If you just need high brightness you can put the nOE pin that is supposed to go to the D8 to Vcc.Ģ.- When trying to control the brightness the display speeds up the letters making it unreadable. Hi, I am working with the same configuration and I have the same problem and some others:ġ.- While working with the original DMD2 library and the examples it gives low brightness SPIDMD dmd(2, 1) // Number of P10 panels used X, Y // change the “SPIDMD”, this is very important to change this ESP8266 moduleĭMD_TextBox box(dmd, -4, 0, 32, 16) // x, y change text posistion ĭmd.setBrightness(255) // Set brightness 0–255 copied from Control LED Screen Panel with Wemos d1 mini | by Tharindu Darshana Peiris | Medium It displays what’s supposed to display, so I have no idea… It is a little bit brighter than without the external power, so that’s connected. I tested with the original controller and it burns my brain indoors, so the power and leds are ok. I have used it with a DUE before, which is also 3volts, so I hope that’s not it It all seems to work well, but… The brightness is VERY low… I tried my first nodemcu + dmd2 combination for the very first time.
