An example schematic with one controller (a microcontroller), three target nodes (an ADC, a DAC, and a microcontroller), and pull-up resistors R p. I 2 C uses only two signals: serial data line (SDA) and serial clock line (SCL). Both are bidirectional and pulled up with resistors. [2]
A liquid-crystal display (LCD) in a smartphone Layers of a color TFT LCD. 1: Glass plates. 2+3: Horizontal and vertical polarizers. 4: RGB color mask. 5+6: Horizontal and vertical command lines. 7: polymer layer. 8: spacers. 9: thin film transistors. 10: front electrode. 11: rear electrode.
Bit banging is a term of art that describes a method of digital data transmission as using general-purpose input/output (GPIO) instead of computer hardware that is intended specifically for data communication.' [1] Controlling software is responsible for satisfying protocol requirements including timing which can be challenging due to limited host system resources and competing demands on the ...
The International Obfuscated C Code Contest (abbreviated IOCCC) is a computer programming contest for code written in C that is the most creatively obfuscated. Held semi-annually, it is described as "celebrating [C's] syntactical opaqueness". [1] The winning code for the 27th contest, held in 2020, was released in July 2020. [2]
For example, a liquid crystal can flow like a liquid, but its molecules may be oriented in a common direction as in a solid. There are many types of LC phases, which can be distinguished by their optical properties (such as textures). The contrasting textures arise due to molecules within one area of material ("domain") being oriented in the ...
Examples of ChLCs range from scarab beetle shells to liquid crystal displays. [2] Many natural molecules and polymers spontaneously form the cholesteric phase. ChLCs have been used to manufacture products ranging from smart paints to textiles to and sensors. Scientists often employ biomimicry to develop ChLC-based materials inspired by natural ...
In this code example, the registers of the x86-64 processor are named and manipulated directly. The function loads its 64-bit argument from rdi in accordance to the System V application binary interface for x86-64 and performs its calculation by manipulating values in the rax , rcx , rsi , and rdi registers until it has finished and returns.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
