====== Laser Show Controller Project Main Page ======

=== Current status ===

  * The controller that was originally planned PIC18F67J60 has integrated Ethernet controller but the chip is very new and there are many issues with it.
  * controller that we will use is dsPIC30F3011 [[http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1335&dDocName=en010336|Datasheet]]
  +This microcontroller is one of the parts that can be used for entries to [[http://www.circuitcellar.com/microchip2007/parts.html|Microchip design contest 2007]]
Criteria to select the microcontroller: 
  -Number of pins >40 and <44
  -Built in EEPROM (for cal data and parameters storage)
  -dsPIC to have DSP core to perform pattern generation
  -Dual UART for Communication and for DMX interface
  -Memory size =>24K (for TCP/IP stack implementation)
  -Package TQFP to optimize size and layout
  -Volume price <5$

  +It has enough memory to implement TCP/IP stack
  +It may be possible to implement the PoE directly ising PWM built in the chip itself
  -We do not have the CCS compiler for dsPIC at tis time. We will have to go 
   through the ordeal of using Microchip MPLAB, ICD2 and C30 compiler. 

  * The Ethernet controller will be ENC28J60

ToDO:

  - Ivo: Design the Schematic diagram based on the schematic diagram with DSPIC30F3011-30I/PT
  - determine what to use for POE http://www.silvertel.com/poe_products.htm
  - Design PCB using [[pcb_design_guideline|PCB design guidelines]]
  - Determine what protocol or driver is necessary for the LFI player 
  - Determine what box to use, select a box from www.digikey.com
  



==== Project definition ====

The Laser Controller is a device that converts digital data from the PC based laser show player software to analog and digital signals necessary to drive laser projector with [[http://www.laserist.org/|ILDA]] compatible interface. 

=== Interfaces ===

  -input 5V supply
  -USB/serial interface for debugging and possibly for local use 
  -Ethernet interface 1BaseT
  -DMX interface  
  -DB25 Female connector for the Laser projector,with  [[http://www.pangolin.com/LD2000/qm2000pinouts.htm|ILDA standard connection]]

=== Block diagram ===

  

==== Software used ====

Firmware: PIC firmware will be written in CCS [[http://www.ccsinfo.com/content.php?page=compilers|PCWH C compiler]]

Software: PC side will be using ILDA file format player that will decode ILDA file and send it via interface to the Laser Controller.
