The diagram below shows potentials of the A (blue) and B (red) pins of an RS-485 line before, during, and after transmission of one byte (0xD3, least significant bit first) of data using an asynchronous start-stop method. B (U+, inverting) signal shown in red, A (U−, non-inverting) signal shown in blue
FTDI TTL-232RG: USB to UART cable FTDI FT232RL: USB to UART IC (in SSOP package) Internal die of FTDI FT232RL chip. FTDI was founded on 13 March 1992 [3] by its current CEO, Fred Dart (whose initials happen to be "FTD"). The company is an indirect descendant of Computer Design Concepts Ltd, a former semiconductor technology startup also founded ...
Board real estate and wiring savings compared to a parallel bus are significant, and have earned SPI a solid role in embedded systems. That is true for most system-on-a-chip processors, both with higher-end 32-bit processors such as those using ARM , MIPS , or PowerPC and with lower-end microcontrollers such as the AVR , PIC , and MSP430 .
Example of a UART frame. In this diagram, one byte is sent, consisting of a start bit, followed by eight data bits (D1-8), and two stop bits, for a 11-bit UART frame. The number of data and formatting bits, the presence or absence of a parity bit, the form of parity (even or odd) and the transmission speed must be pre-agreed by the ...
Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...

A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
n November 1954, 29-year-old Sammy Davis Jr. was driving to Hollywood when a car crash left his eye mangled beyond repair. Doubting his potential as a one-eyed entertainer, the burgeoning performer sought a solution at the same venerable institution where other misfortunate starlets had gone to fill their vacant sockets: Mager & Gougelman, a family-owned business in New York City that has ...
