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.
Hi
I recently registered on this site as a last resort for my pensioner mother who's at the end of her tether. For the last 12 months she's been hearing banging noises from the pipes. It sounds similar to someone banging several times on the wall and it appears to originate from the immersion...
Hello folks.need advice. My water pipes bang at irregular intervals day and night even when nothing's on.

Hi,
I am looking for some guidance regarding a problem that has developed with my central heating system.
A couple of days ago, the pipework started banging/knocking when the heating was going on and when it is cooling down, this banging can vary from a large thud to a series of regular bangs...

Fitted quite a few (50+) Main 30Eco's with no probs but last three I have fitted have suffered from explosive ignition. Customers complaining that the boiler is 'banging' occasionally. Anybody else had it? Main technical are no help and I've checked all ignition components with nothing obvious.

Hello All,
We have a small Worcester Bosch Junior 24i boiler which is making a loud banging noise when operating.
If a radiator valve or TRV is adjusted (turned), the noise disappears.
Is this likely to be a faulty radiator valve, TRV or something else?
The boiler has 3 radiators attached to...
Hello,
After a leak, a new valve has been fitted on one of my radiators ( referred as the radiator) . Since that day we have a banging noise coming from the floor under the radiator. The plumber came back 1 month and a half later and did another radiators' bleeding . But that hasn't solved the...

My mum had a BG combi boiler fitted 6 years ago to replace an old boiler on a 35 year old central heating system.
She's had a Homecare 400 contract to service the boiler annually; all fine until this year.
It was serviced 2 weeks ago; apparently all ok. The house isn't being lived in full...

Just been fitting a shower for a customer and just as the job was finished he asked what I'd charge for fitting the new cooker that is coming next week. Told him £45 plus any parts etc. He said to use the old hose and the bayonet was already installed and a safety chain also there. "Will just...
Hi all,
Last autumn/winter whenever I used the kitchen or bathroom hot water taps the pipework would gently hum for a few seconds and then disappear. As the weather got warmer the problem went away. This also coincided with me turning the central heating off.
However, now that it's getting...
