Last time, I talked about setting up my Pi Pico by soldering on the GPIO pins and wiring up an LCD screen. Having something work is obviously no fun. I need another challenge.

I decided to update the display to show the current temperature. I’d read that the Pico has a built-in temperature sensor, so how hard could it be?

I quickly took the sample code from the Pico website and plugged it in. It ran first time, which is quite impressive, and said that it was currently… 10º.

It’s been a productive weekend, at least if you consider doing unnecessary things productive.

For reasons that won’t become clear any time soon, I decided that I wanted to get some of my Arduino components working with my new Raspberry Pi Pico. Like the Arduino, but unlike other Pis, the Pico is a microcontroller. In practical terms – for a programmer at least – this means it doesn’t have a “proper” operating system like Linux but it does have lots of inputs and outputs, both digital and analogue.

When people say that Twitter is a cesspool of conspiracy and abuse, I don’t recognise it based on my experience. My Twitter timeline is all jokes and geeky chat¹, and that’s where this post takes its cue:

When I started learning assembler, no site ever mentioned what registers were good for. Wish it had said:

CPU talking to a RAM chip is slow, registers are a bit of memory built into the CPU in which you load numbers from RAM, do several calculations, and only THEN write back.
