Watched this one from Ben Eater: SPI: The serial peripheral interface. I found it while watching this one: Hacking a weird TV censoring device, which was kind of hilarious, he reverses a profanity filter and finds its dictionary.

I noticed Ben Eater has a Keysight DSOX1204G Oscilloscope, a pretty nice looking bit of kit. Oh dear, he also seems to have a Keysight DSOX4024A Oscilloscope, which is an even nicer looking bit of kit.

When I have some time I’m gonna get some of these BME280 knockoffs and see if I can play along with the SPI video.
