This is my latest work of an electronic USB board able to connect with any Macintosh system.
The FGIO_USB board is a general purpose Digital Input and Digital Output 16+16 channel managed by a Microchip 18F4550 microcontroller.
The board use different bus technogies for handling electronic communication with on board device.
It uses I2C in order to communicate with on board 256Kb EEPROM, SPI for communicating with the MCP23S17 chip (it is a Microchip 16 I/O Expander) and for communicating with 128 x 128 Graphic LCD Color Display (Nokia 6100). |
This is
the prototype board

is available for industries that
would commercialize it!

Features
- It manages 16 digital input line
and 16 digital output line
- It manage EEPROM data
(Both internal EEPROM micro and External chip)
-It manage a 128 x 128 LCD Graphic display
The base software for Mac OS X represents a group of COCOA classes which all developers can freely use and extend.
FGIO_usb future features
(I hope :-) )
- it’ll read extenal temperature
- it’ll read external humidity
- it’ll interfacing wireless xbee
module
- it’ll intefacing Compact Flash
