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.

    Changing expansion vessel?

    After the plumber changed the expansion vessel, the boiler was leaking even worse leading it to being condemned. It is quite old, so I suspect it was on its last legs anyway. Still, he was banging it quite a lot, and I just wanted to check there was a good reason for him to do so. Thanks.

    Boiler making banging sounds and pressure fluctuates

    Hi, We recently moved into a new rental property and have had issues with the heating. The house has a Baxi boiler, and when we moved in it wasn't working, with an E119 error, but this was easily fixed with topping up the water. However, about twice a week I need to do a top-up, so there must...
