The Modular Lighting Controller will control various kinds of lighting via various protocols/interfaces, or convert between two of the supported protocols/interfaces without directly controlling any devices.
Project Log
- 2012-06-12 - Chose connectors, laid out basic core board interface components/defined sizes.
- 2012-06-06 - 2012-06-11 - Defining specs, searching for appropriate parts.
Project Ideas
- Core board, lets you plug in up to 4 input modules and 4 output modules
- Each of the 4 would be up to one DMX universe worth of channels (512)
- SPI to each I/O module, 8 SPI transceivers total
- RS232 for troubleshooting and configuring the core board itself
- Local framebuffer memory
- Dual-port memory would be best so the output and input sections can both deal with it independently
- 8 bits per frame * 512 channels per universe * 4 universes = 16kbit (2kbyte) of framebuffer memory required
- Twice that for double-buffering would be awesome, so 32kbit/4kbyte of dual-port memory wanted
- Split into 4 channels, so each block would be 8kbit/1kbyte
- Reading/writing needs to happen in parallel for each block
- CPLD/FPGA seems a great fit for this
- Lattice LFXP2-5E-5TN144C or Xilinx XC3S50-4VQG100C both seem like good fits
- Since this will likely be the most powerful chip in the whole system, we could do transforms here to to take the load off the I/O modules
- HSV->RGB
- Input splitting (one input channel goes to two or more output channels)
- Input combining (two or more input channels get combined via some function and go to a single output channel)
- Scaling/offsetting (0-255 in = 32-64 out or such)
- Inputs
- Art-Net over Ethernet
- Art-Net over WiFi
- DMX
- Analog input channels (not 512 though, likely)
- Outputs
- LPD8806 LED strips
- Other LED strips
- Art-Net over Ethernet
- Art-Net over WiFi
- DMX
- Discrete power switches (relays/FETs/whatever)
- Dimensions
- Core board will be 3.95" x 6.25" (max limits of EAGLE Standard, will need to purchase)
- Modules will be 1.525" x 1.925" (2x4 layout on the board for input/output x 4 channels)
