Note : Download the microcontroller when the need for cold start (meaning that the microcontroller needs to power off and then re-power to download), the power switch as a cold start on the line, download the device is connected to the need to disconnect the switch and then re-power can be downloaded, Host computer connection method (no cold start, do not dial the power cord and then plug), with the power cord directly on the line.
įourth,Start burning,when click 'ISP programming',at the same time press the power button twice, power off and then power on. Third,choose the right COM (Automatic Identification). Upper computer function & Burn the program introduction:Ĩ.You can download the code here,modify and compile programs by keil ,then burn the program by STC-ISP-V4.86.įirst,choose the right MCU (STC12C5A60S2). Created and edited by Brand James, the cube will start to play SD animation file than play the animation code in the firmware, programmed code can create. K4 key: enter 14 kinds of offline audio mode (after the boot to press the K1 key is valid).K3 key: to enter the 42 kinds of offline animation mode (after the boot to press the K1 key is valid).K2 key: enter the 3D8 PC mode (after the boot to press the K1 key is valid).K1 key: enter the mode selection, day and night mode control.The final circuit uses a 2N2222A NPN-Transistor and a FQP27P06 P-Channel MOSFET for each layer, and no extra transistors for the shift registers. This resulted a lot of unnecessary circuit, which I was later able to eliminate.
I made a mistake in wiring the ground of the shift register to the AREF pin of the Arduino instead of GND. However, it took many more hours to build compared to the usual led cube. The result is an impressive 11"x11"x11" cube. Larger cube also meant more fragile cube. More soldering, having to deal with alignment of the extra wires. My desire to spread the LEDs beyond the length of the LED leads added a LOT of complexity to the cube construction. Quickly setting up which of those LEDs on that layer should be on and then repeating that for the other layers, gives the illusion that we can individually control every individual LED. I decided that I'm not ready for RGB version yet, so I'm only building single color.Įlectrically, the cube is made up of 64 pillars containing 8 LEDs each.Įight 8-bit shift registers (74HC595) supplies the GROUND for those pillars.Įach layer of the cube shares a common +5V switched by a P-Channel MOSFET, for a total of 8 MOSFETs.Īt any time, a maximum of 64 LEDs of ONE particular layer would be all lit up. I found the 4x4x4 RGB cube very rewarding to build so I'm moving up to 8x8x8.
