Charlieplexing

Index Charlieplexing

Charlieplexing is a technique for driving a multiplexed display in which relatively few I/O pins on a microcontroller are used e.g. to drive an array of LEDs. [1]

AEG

Allgemeine Elektricitäts-Gesellschaft AG (AEG) (German: "General electricity company") was a German producer of electrical equipment founded as the Deutsche Edison-Gesellschaft für angewandte Elektricität in 1883 in Berlin by Emil Rathenau.

Binary number

In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically 0 (zero) and 1 (one).

Bus (computing)

In computer architecture, a bus (a contraction of the Latin omnibus) is a communication system that transfers data between components inside a computer, or between computers.

Diode matrix

A diode matrix is a two-dimensional grid of wires: each "intersection" wherein one row crosses over another has either a diode connecting them, or the wires are isolated from each other.

Display device

A display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people).

Duty cycle

A duty cycle is the fraction of one period in which a signal or system is active.

General-purpose input/output

A general-purpose input/output (GPIO) is an uncommitted digital signal pin on an integrated circuit or electronic circuit board whose behavior—including whether it acts an input or output—is controllable by the user at run time.

High impedance

In electronics, high impedance means that a point in a circuit (a node) allows a relatively small amount of current through, per unit of applied voltage at that point.

Light-emitting diode

A light-emitting diode (LED) is a two-lead semiconductor light source.

Lossy compression

In information technology, lossy compression or irreversible compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content.

Multiplexed display

Multiplexed displays are electronic display devices where the entire display is not driven at one time.

P–n junction

A p–n junction is a boundary or interface between two types of semiconductor materials, p-type and n-type, inside a single crystal of semiconductor.

Persistence of vision

Persistence of vision refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye.

Refresh rate

The refresh rate (most commonly the "vertical refresh rate", "vertical scan rate" for cathode ray tubes) is the number of times in a second that a display hardware updates its buffer.

Seven-segment display

A seven-segment display (SSD), or seven-segment indicator, is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.

Three-state logic

In digital electronics three-state, tri-state, or 3-state logic allows an output port to assume a high impedance state, effectively removing the output from the circuit, in addition to the 0 and 1 logic levels.

Voltage

Voltage, electric potential difference, electric pressure or electric tension (formally denoted or, but more often simply as V or U, for instance in the context of Ohm's or Kirchhoff's circuit laws) is the difference in electric potential between two points.
