NordicSemi name comes up when battery operation is a requirement and it's used
widely in commercial products but I don't know much about it.
As you pointed out Pi Pico and especially Espressif SoC power consumption is
not great. I love Pi Pico for ease of use with it's build in USB (MSC mode!)
I think a good thing to look at is power. Raspberry pi pico seems to draw 25mA
if idle and 390uA dormant, compared to the attiny85's 2mA and 1µa dormant. So
if you don't need the pi's features, you can run an attiny85 a lot longer on a
coin cell.
I made a similar comparison once when I was look
"small" is the keyword here. Both of those chips are super capable with tons of
features. If all you need to do is read some sensors and handle some outputs
the Attiny85 is a great little chip.
It has a nice web site and a pleasing demo on the first page! That counts for
something. Don't worry, I expect plenty of swearing and hair-pulling later.
The application requirement is 'just slightly more functional than soldering
logic transistors'. At my current stage of learning, things like radio and
encryption are still Alien technogy.
Is it really Attiny85? Probably depends on a project. At least for IoT the
choice seems to be NordicSemi, Espressif ($3ea) as well as Pi Pico ($1ea).
Polished might be a bit optimistic. Ratel is neat, but it should definitely
improve. The idea behind it was simply to make a common interface for dealing
with microcontrollers so that Nim could progress away from the "ugly shell
script and lots of boilerplate" stage and into something a bit more
Oh wow I was expecting an ugly shell script and lots of boilerplate, not a
polished project for writing idiomatic Nim code. I'm stoked.
Hello!
It's true that I've programmed the Attiny85 in Nim, but better yet I've written
a library which helps with the process. [Ratel](https://ratel.peterme.net) runs
on the Attiny85 (in the shape of a Digispark, but if you home-brew it the
solution would be pretty much exactly the same). Simpl
Hello, everyone!
I've been toying with some electronics lately, trying to reach more physical
areas with my programming. I ruined a good few pieces of perfboard and some
hapless parts in the process- it's funny how in hardware each of your learning
experiences come with a size and weight attach
