The pigpio library for GPIO control supports hardware timing for PWM and servo outputs, which provides much more accurate and jitter-free control. It can be used from gpiozero by setting the pin factory.
However, for some reason, pigpio is not included in the latest version (“trixie”) of Raspberry Pi OS. This post summarizes how to build it from source.
I have an audio project (streaming radio) running on a Raspberry Pi. When I tested it on the latest version of the OS (“trixie”) I couldn’t get the audio to work. This post explains how I got it to work.

As an addition to the examples of work page, this is a summary of some of the work I have done recently as a ghost writer (so no details available):
Continue reading “Summary of recent work”I have been doing more work on flash memories and decided to write up the notes I have been taking.
This article is about the technology behind flash memory: how data is stored, the architecture of flash memories and (briefly) how data is read, written and erased. (This may turn into a series with more detail on various aspects of flash technology.)
Continue reading “Flash memory”Solid-state drives (SSDs) based on flash memory are increasingly replacing hard disk drives (HDDs) for mass storage in many applications. A quick check of an online retailer showed that about half the laptops and desktop computers used SSDs.
