7-Segment Serial Display
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.
- Limits the number of microcontroller pins needed to control 4-digit display
- 9600 default baud rate
- Pins broken out to a 0.1" pitch header
- Overall Display: 40.18 x 12.8 mm (1.58 x 0.50")
- Digit Height: 10mm (0.39")
Hooking it up
The Serial 7-Segment Display uses either 1 wires for serial TTL communication with a microcontroller, or 3 wires for SPI serial communication. With both methods, display data is sent in 4-byte packets (one byte for each digit), and special commands are sent in 2-byte packets. The use of 4-byte display data can be circumvented with special commands, as they allow you to write output to specific digits.
