Serial 7-seg Display Board

Serial 7-seg Display Board


The Serial 7-Seg Display Board is a compact display board that employs a MAX7219 serial input/output common-cathode display driver. This display driver is used to create an interface between microcontrollers and 7-segment numeric LED displays. It uses SPI communication interface for communication between the additional board and a microcontroller. It also features four 7-segment LED displays arranged in a single row that allow the user to display digits. The Serial 7-Seg Display Board features a flat cable with IDC10 female header connector on the end, which makes it compatible with all new mikroElekronika development boards. It also provides easy adjustment of connector pinout using DIP switches.

This display board is an ideal choice for applications that require a four 7-segment digit display while saving microcontroller pins and processing power. Such applications include bar graph displays, industrial controllers, led matrix displays, panel meters, and so on.

IC/Module: MAX7219 LED Display Driver

MAX7219 is a serially interfaced 8-digit LED display driver IC equipped with a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM for storing digits. The external resistor is required to set the segment current for all LEDs. This display driver allows the user to select code-B decoding or no-decode for each digit.

SMD Jumpers

The position setting of SMD jumpers depends on the development system to connect to. By default, the jumpers are set to PIC position. In case, the user wants to use it with AVR/8051 development systems, the user must unsolder them and resolder them in the AVR/8051 position.
