Boards Overview
Several boards make up the design goal of;
- 32 solenoids / flashers
- 128 switches
- LCD
- Stereo Sound
This is the heart of the system, its basically a large 'shield' board that a Sparkfun UBW32 board plugs into. It runs the rules, reads the switches, etc
This board contains 32 MOSFETs for driving high power parts such as solenoids and flashers. Its does low side switching. This board is monitored by a Parallax Propeller chip for doing the high speed timings. The board itself is fed as a bank of 4 shift registers, so you can easily use this board standalone with something else that can do accurate millisecond timing.
The light board will have two channels, one channel for the LED GI lighting, and a second channel for inserts. Using WS2803 control chips, each chip can address 18 single colour LEDs or 6 RGB LEDs each. The goal is for 72 single colour GI using 4 chips and 48 RGB LED inserts using 8 chips.
The raspberry pi is used to drive the LCD and play WAV/MP3 files out to a USB DAC that feeds a car amplifier.
The Raspberry PI is fed data by an rs232 signal so any other small computer can be utilised in place of the RPI.
Currently its written to use SDL2, which on the RPI outputs directly to OpenGL with hardware acceleration.
