# Title: Serial 7-seg Display Board ## Description: The Serial 7-seg Display Board features a compact, serial input/output common-cathode display driver MAX7219 used to interface MCUs to 7-segment numeric LED displays via SPI interface. The chip includes a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers and 8x8 static RAM for storing digits. Display drivers are connected to 4 common-cathode LED displays. The board is equipped with a flat cable ending with IDC10 female header connector, which is compatible with all mikroElektronika development boards. It features four 7-segment digits arranged in a single row. How to Connect the Serial 7-seg Display Board? The additional board is connected to a development system via an IDC10 connector on the board and a 2x5 connector on one of the development system's ports. It is necessary to define in the program, to be loaded into the microcontroller, which port will be used for SPI communication. The position of SMD jumpers depends on the development system in use. These jumpers are placed in the position marked PIC by default. It means that the board is ready to be used with PIC development systems. If you want to use it with AVR/8051 development systems, it is necessary to unsolder jumpers from the PIC position and resolder them in the AVR/8051 position. The Serial 7-Seg Display additional board is powered with the 5V power supply from the development system it is connected to. Displaying Digits Displaying digits is enabled by the time-division multiplexing. All the operations related to multiplexing and displaying digits are performed by using the MAX7219 circuit provided on the additional board. The time-division multiplexing of a 7-segment display is based on fast turning the display segments on/off in such a manner that one gets an impression that all eight digits are active at the same time. The MAX7219 circuit feeds digit segments with a signal via pins marked SEGxx, whereas pins marked DIGx are used to select one of four displays to show the appropriate number. ## Product type: Display ## Vendor: Mikroelektronika d.o.o. ## Tags: Display Interface, Interface Board, MikroE ## Price range: 24.5 - 24.5 GBP ## Link: https://thedebugstore.com/products/mikroe-201-serial-7-seg-display-board-uk ## Compare-at price range: 35.0 - 35.0 GBP ## Options - Title: Default Title ## Collections - [New Products](https://thedebugstore.com/a/llms/collections/new-products-debug-store) - [Mikroelektronika d.o.o.

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.

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.
