In circuit diagrams and circuit analysis, there are long-standing conventions regarding the naming of voltages, currents, and some components. [5] In the analysis of a bipolar junction transistor, for example, in a common-emitter configuration, the DC voltage at the collector, emitter, and base (with respect to ground) may be written as V C , V ...
Short for Improved Inter-Integrated Circuit, [4] the standard defines the electrical connection between the chips to be a two wire, shared , serial data bus, one wire (SCL) being used as a clock to define the sampling times, the other wire (SDA) being used as a data line whose voltage can be sampled. The standard defines a signaling protocol in ...
The STM32 F4-series is the first group of STM32 microcontrollers based on the ARM Cortex-M4F core. The F4-series is also the first STM32 series to have DSP and floating-point instructions. The F4 is pin-to-pin compatible with the STM32 F2-series and adds higher clock speed, 64 KB CCM static RAM, full-duplex I²S, improved real-time clock, and ...
This configuration only requires a single CS line from the main, rather than a separate CS line for each sub. [ 7 ] In addition to using SPI-specific subs, daisy-chained SPI can include discrete shift registers for more pins of inputs (e.g. using the parallel-in serial-out 74 xx165) [ 8 ] or outputs (e.g. using the serial-in parallel-out 74 ...

For example, for a 14-lead DIP, with the notch at the top, the left leads are numbered from 1 to 7 (top to bottom) and the right row of leads are numbered 8 to 14 (bottom to top). Leads are skipped on some DIP devices (e.g. segmented LED displays , relays, or devices that replace leads with a heat sink fin).
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.
A symmetric layout of Charlieplexed LEDs. On left, 3 pins drive 6 LEDs arranged in a triangle. On right, 4 pins drive 12 LEDs arranged in a tetrahedron.. The Charlieplexing configuration may be viewed as a directed graph, where the drive pins are vertices and the LEDs are directed edges; there is an outward-pointing edge connected from each vertex to each other vertex, hence with n drive pins ...
