4-digit LED display as i2c bus slave device

[BlackMamba]

Project presents 4-digit 7-segment LED display designed as i2c bus slave device. It is dedicated to 8051 controller evaluation board, however it can be applied in other devices as well.

Device is based on the AVR (AT90S2313) microcontroller. I2C bus slave mode is implemented.
Device can display 4 digits and one comma maximum. Data for display create predefined frame.
Device was assembled on the single-sided printed circuit board 105x55 mm.
