The PIC HomeCockpit Controller (PHCC)
PHCC Overview
The system consists of a motherboard and a variety of application specific daughterboards.
What is it?
Features:
- cheap
- modular and extensible
- one 100x160mm "motherboard"
- daughterboards for switch controllers, display controllers, stepper controllers, digital out, servos, USB
- if other solutions don't cut it anymore :-)
- up to 1024 switches/push buttons
- why so many ?
- count things up: 3 CDUs, glareshield, MIP, pedestal, overhead, circuit breaker overhead, and more
- can be upgraded in steps of 64 per daughterboard
- why so many ?
- 35 channels analog in
- 3 primary: eg for aileron,elevator,rudder
- 32 secondary: eg for throttles, reversers, toe brakes, steering tiller, radio volume control, brightness,...
- unlimited 8bit digital out channels, used for:
- 7 segment displays (including the often neglected decimal point)
- LEDs
- stepper control via H-bridge drivers
- character LCDisplays
- Relays/solenoids
- lamps/Korry switches and indicators
- servos
- analog out (ADC using PWM)
- uses 1 RS-232 Serial Port
- USB daughterboard available
- based on a PIC 18F4X2
- uses standard components: MAX232, serveral 74HCxxx and 74HCTxxx
- costs: (not counting the displays, LEDs, switches, pots, steppers and servos)
- motherboard: about 35-40 EUR (includes all analog in channels)
- daughterboards
- switch controller 5-10 EUR every 64 switches. (about 2 EUR if you have switches w/ built-in diodes and you want to solder everything on the board)
- check subpages for details of other daughterboards
- all software is open source/free software according to GPL
- this includes
- firmware (PIC assembly language)
- and controlling software on the host (PC) that talks (at least) to the flightgear simulator (FlightGear)
- kernel drivers (eg. for the analog channels used for joystick input)
- usually third party software is also released as open source, or at least as freeware
- this includes
