Sparkfun - 7 - segment serial display com-09230
The 7-Segment Serial Display turns the thirteen pins necessary to control a 4-digit 7-segment display into just one or three. The display will give you full control of all digits, decimal points, the colon and the apostrophe. At the heart of the display is an ATMega168 which controls all the serial communications and the 4-digit 7-segment display through an easy to use API.
The Serial 7-Segment Display can be controlled in one of two ways: (1) serial TTL communication or (2) SPI serial communication. Regardless of which method you use to communicate with the display, the display is controlled with 4-byte packets and special 2-byte commands.
* 4 digit Yellow alpha-numeric display with serial (1 pin) or SPI interface (3 pins)
* Display numbers (0-9) and letters (A-F)
* Control multiple decimal points, apostrophe, and colon
* Selectable baud rate (4800 to 57600 bps)
* Selectable brightness (255 different levels)
