About

---------

Source code and all files for the generic 8x8x8 3D LED Cube found on eBay 

(having STC 8051-based STC12C5A60S2 mcu), aka. 3D LightSquared 8x8x8 LED Cube DIY kit, ideasoft etc.

`Note`: as received from manufacturer with additional cleanups/optimizations.

Firmware v2

---------

The `firmware/v2` directory contains an optimized and more advanced version of the ledcube firmware.

All animations were removed except one and UART/serial based control was implemented. 

So the cube can be controlled with Arduino/Atmega or simple PC serial console.

`Note`: The ledcube UART control mode is activated once the first command comes over serial connection.

The new firmware can be flashed/written to STC MCU through UART/serial connection. 

Software such as STC-ISP is required to transfer the hex file (machinecode) to the STC microcontroller. 

`Download here`: http://www.stcmcudata.com/STCISP/stc-isp-15xx-v6.86R.zip

##### Serial connection: 

* USB-2-TTL converter/adapter/module can be used to connect to PC (e.g. search eBay)

* Parameters: baud - 9600 bps, 1 stop bit, no parity

* Cube UART pins: VCC, GND, P30(RXD), P31(TXD)

##### Programming STC

* Connect serial module to ledcube serial pins, RX to TX, TX to RX

* Open STC-ISP and select STC12C5A60S2 and serial port

* Select HEX file: ledcube8.hex and press `Download/Program` or `Re-Program`

* Reset power to MCU to start programming

##### Alternative programming/flashing tool: STCGAL

If you have trouble with the official STC-ISP, try using:

##### Extra - C51 project

Keil uVision C51 project file is also available in the `firmware/v2` directory if compiling the source code is a must.

Keil C51 compiler tools are required to open the project.

`Download here`: https://www.keil.com/demo/eval/c51.htm

The required STC mcu C headers need to be installed from the STC-ISP tool via "Keil ICE Settings" tab.

Use the "Add MCU type to Keil" button and point to your Keil install directory.

Firmware v2 for SDCC

---------

SDCC compiler supports compiling code for STC12C5A60S2. 

Adapted version of v2 firmware for SDCC can be found in `firmware/v2-sdcc` folder (created by Michael Knyazev).

LED Cube control

---------

![Control program](https://raw.githubusercontent.com/tomazas/DotMatrixJava/master/help/program_view.png)

The cube (with Firmware v2) can be controlled over serial port/console with: [PC Program](https://github.com/tomazas/DotMatrixJava). 

Program allows to create animations and playback them.
