banging

In computer engineering and electrical engineering, bit banging is slang for any method of data transmission that employs software as a substitute for dedicated hardware to generate transmitted signals or process received signals. Software directly sets and samples the states of GPIOs (e.g., pins on a microcontroller), and is responsible for meeting all timing requirements and protocol sequencing of the signals. In contrast to bit banging, dedicated hardware (e.g., UART, SPI interface) satisfies these requirements and, if necessary, provides a data buffer to relax software timing requirements. Bit banging can be implemented at very low cost, and is commonly used in embedded systems.Bit banging allows a device to implement different protocols with minimal or no hardware changes. In some cases, bit banging is made feasible by newer, faster processors because more recent hardware operates much more quickly than hardware did when standard communications protocols were created.

    Glow Worm Flexicom SX popping and banging

    To a layman the gas is arriving before the spark. In car terms the timing is retarded. Hopefully the installer wasn't! No fault code, just 1.2 bar displayed. 1 yr old. Seemed to start after a power down and restart. Thanks in advance.

    Pipes Banging

    Once my heating shuts off after been on the pipes dont half make a noise, am guessing its just water hammer but if anyone know any different let us know? Never used to do it so maybe the boiler is to blame.
