Arduino led cubes code#

These functions are part of the Arduino class, which is fundamentally a C++ class. When programming Arduino, to control the Input/Output (IO) pins, one uses digitalWrite(HIGH) and digitalWrite(LOW).

Arduino led cubes code#

However, it’s entirely possible with little to no effort to upload the code to a standalone Atmega328, using Atmel Studio, if you don’t wish to use an Arduino. The project was based on using the bootloader inside the Arduino board to upload the code. However, the code is fully compatible with the Arduino board and can be uploaded with the Arduino IDE. This gave a better and more efficient code. These reasons led the motivation to write the code in C rather than to use Arduino’s C++ framework. In a LED cube, speed is very important, as well as memory for the light patterns. This can be limiting, because the Arduino framework is an abstraction layer that causes the Atmega328 to run slower than its potential. However, to program the chip on an Arduino board, one usually programs it with the Arduino IDE using the Arduino framework. The Arduino board is constructed with the microchip Atmega328.

Supporting video tutorials found at YouTube(coming soon). The code was developed together with the Cube 3D programming tool. This project contains the code for a LED cube, using an Arduino board or the Atmega328 as a standalone with Atmel Studio. I was able to deduce this time on my Mega, but struggling on my Due.LED-Cube-Code LED Cube Code for Arduino or Atmega328 From the last bit of one byte to the first bit of the next is around 1.3µs, 3 time longer than the whole byte took to send. Right now the start of one byte to the start of the next is 1.7µs. The issue now to improve is to reduce the time between each byte of data being sent via SPI at each update. My first cube was also a 4x4x4 Red LED cube.Īs for my 'Cuboid', I have it looking good and bright now with minimal off time. '8x8x12 Rectangular Prism', although I did make mention of it on my YouTube, and 'Cube' is easier to spell. But I have found that you don't get a good response to titles like Thanks Paul (How to post a link), still learning my way around on this site.Īnd you also correct, its a Rectangular prism. I will tackle an rgb 4x4x4 cube one day soon, but was planning on using ws2812b leds for that. I have built 4x4x4 single colour cubes of my own design. That's not a cube then, is it? You could call it a 'cuboid'!Īlso, this is how you post Link on this forum.īut, well done indeed on the construction. Void LED(int CY, int CX, int CZ, int CR, int CG, int CB) //************** END Tranfer ************************/Īnother advantage to the increasing time method for updating, it gives more time back to the processor to compute the next part of the animation. Why x 6, cos any more will give repeat colours. #define BAM_RESOLUTION 4 // EG 4 bit colour = 15 variation of R, G & B (4096 colours)Ĭonst byte Size_Y = 12 //Number of Layers Y axis (levels/Layers)Ĭonst byte Size_X = 8 //Number of LEDs X axis (Left to right across front)Ĭonst byte Size_Z = 8 //Number of LEDs Z axis (front to back)Ĭonst int Size_Layer = Size_X * Size_Z // Number of LEDs per LayerĬonst int Size_Cube = Size_Layer * Size_Y //Number of LEDs whole Cube.Ĭonst int Size_CW = ((1 << BAM_RESOLUTION) - 1) * 6 //Number of steps in colour wheel. Adding height does not make programming any harder.

Height, I found having a bit more room in the height good for animations.

Yes you will require more memory for more LEDs. As for programming, If you write to your LED array a bit like the code below, having any number of LEDs will work. My next cube will contain an odd number of LEDs.

Having a center will make your animations work better in many cases. The issue with this arrangement is there is no center, so consider making a cube with odd numbers EG 9 x 9 x 9. WHY? Well I guess that 8 fits AVR architecture nicely. Everyone talks about a cube that is 8 LEDs wide, 8 LEDs deep and 8 LEDs high (8 x 8 x 8 = 512 LEDs). Very much following the concept designed by Kevin Darrah (on )Ĭheck out my cube here RGB LED Cube 'Rectangular Prism' Bragging Rights | All modding! | įirst thing. My Cube is 8 x 8 x12high, using 5mm RGB LEDs. Thought I would put up a thread about my cube and things I know now, after make a cube and running my cube for a few years. I have looked around and see a lot of information out there about RGB LRD cubes, some good some not so good, IMHO.
