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.
was wondering if anyone could offer any advice, the system was recently drained for a radiator to be changed.
After refilling all rads were bled, as well as a bleed valve situated near the cyclinder.
The radiators are working fine if anything they appear to be a little hotter than normal but...

I live in a new build house. I have a recently bought a fluless gas fire and need an airbrick installing too, I'm concerned about the draft from the airbrick. How much would I be looking at to have a different gas fire fitted plus a flu installed?

I have water hammer when I run cold water anywhere in my flat.
I can only hear it in the cupboard that houses my OSO water tank that was fitted a couple of years ago. This is also where the supply enters the flat.
This could have been happening for some time as I rarely go into this cupboard...
