  2. C standard library - Wikipedia

    en.wikipedia.org/wiki/C_standard_library

    The C library functions, including the ISO C standard ones, are widely used by programs, and are regarded as if they were not only an implementation of something in the C language, but also de facto part of the operating system interface. Unix-like operating systems generally cannot function if the C library is erased.

  3. Hitachi HD44780 LCD controller - Wikipedia

    The same command is sent three times, Function Set with 8-bit interface D7–D4 = binary 0011, the lower four bits are "don't care", using single enable pulses. If the controller is in 4-bit mode, the lower four bits are ignored so they cannot be sent until the interface is in a known size configuration.

    In 1962, the first major English language publication Molecular Structure and Properties of Liquid Crystals was published by Dr. George W. Gray. [20] In 1962, Richard Williams of RCA found that liquid crystals had some interesting electro-optic characteristics and he realized an electro-optical effect by generating stripe patterns in a thin ...

  5. I²C - Wikipedia

    en.wikipedia.org/wiki/I²C

    Since OpenBSD 3.9 (released 1 May 2006; 18 years ago ()), a central i2c_scan subsystem probes all possible sensor chips at once during boot, using an ad hoc weighting scheme and a local caching function for reading register values from the I 2 C targets; [26] this makes it possible to probe sensors on general-purpose off-the-shelf i386/amd64 ...

  6. C mathematical functions - Wikipedia

    en.wikipedia.org/wiki/C_mathematical_functions

    The type-generic macros that correspond to a function that is defined for only real numbers encapsulates a total of 3 different functions: float, double and long double variants of the function. The C++ language includes native support for function overloading and thus does not provide the <tgmath.h> header even as a compatibility feature.

  8. C POSIX library - Wikipedia

    en.wikipedia.org/wiki/C_POSIX_library

    The C POSIX library is a specification of a C standard library for POSIX systems. It was developed at the same time as the ANSI C standard. Some effort was made to make POSIX compatible with standard C; POSIX includes additional functions to those introduced in standard C. On the other hand, the 5 headers that were added to the C standard ...
