My bad.

Point still stands, by a savage and learn assembly 😈

freeCodeCamp has you covered!


I never tried to learn ARM assembly but back in the early 90's we had a couple of Acorn Archimedes computers - I remember the original ARM1 and ARM2 chips at that time only had about 32 instructions in their instruction set.

I have only done x86 and x64 on Linux. with GAS assembly I also played around with SASM on Windows which is cool because it also includes C libs and has an integrated debugger.

SASM - Simple crossplatform IDE for NASM, MASM, GAS, FASM assembly languages

I’ve always wanted to learn how to code some things on a Raspberry Pi, but can’t find the motivation to just buy a kit and google some courses. Is that the best way to learn?

I had a dream of there being some kind group of techies giving courses to adults face-to-face, where everyone learns something and has fun building projects together. Does such a thing exist in Johannesburg? Or is it way too social for programmers?

My personal context is I did a bit of Java programming and now only know how to write JavaScript, which is fine for websites but probably won’t be useful here. I like to think I’m a fast learner though so not put off by having a crash course and just starting with the basics.

Please help, what’s the best places to start?

I know you are looking at a pi but why not look at a pico if indecisive - 80 bucks.

NB: Just remember the pi's are 3v3.

I have zero clue what “3v3” means so remembering this won’t help me lol.

And what’s a pico? Is that related to a pi? Or one of the other microcontrollers people on here spoke about?

A pico is a low cost microcontroller - https://www.pishop.co.za/store/raspberry-pi-pico

3v3 means 3.3 volts. Any input/output must not exceed that voltage.

For learning with, the pico is cheap if you make a mistake compared to the pi's. If you get bored or abandon it - its only R 72 compared to R2500. If you don't have a soldering iron then you need to get the pico h that has the headers on - https://www.pishop.co.za/store/raspberry-pi-pico-h?keyword=pico with headers&category_id=0.

Irrespective whether it is a pi or pico you will need to know how to add interfaces or electronics to it.

Youtube has lot of videos on the basics - rpi or pico.

Get an electronics kit to go with it - you will have to decide which kit to go far - what you want to do - something like this https://www.pishop.co.za/store/raspberry-pi-pico-basic-kit---without-pico?keyword=pico kit&category_id=0

The rpi or pico is essentially useless just by itself, you need the electronic side as well whether it is input or output. So just learning just got a little more complicated than just learning a programming language but is actually easy once you have the basics down. Youtube is extremely handy here. Watch a few introduction videos to get an idea of what you want to do and need.

Thanks for the tip. Are Arduino boards the more basic microcontrollers mentioned earlier on this thread?

Yes, they are a series of open source Microcontrollers rather than Single board computers like the Pi. You can still do many useful things with them.
