@IamKyros69 There were and are always docs. You can learn bash in the terminal by reading application manuals. You can read source code of many open projects to learn any sort of language. There are millions of books on any of these subjects and they were there, being written from the start.
To engineer a robust and efficient system around a particular microcontroller that fits that particular use case, you need to design and build good electronic circuits. What you have mentioned is all great for prototyping but a finished product requires a lot better custom design.
@adafruit@Qualcomm@arduino There seems to be a trend these days of open source ecosystems and not for profit initiatives being eaten up by greedy corporates and other leveraged entities. Data mining going into overdrive in the age of Ai. What will be the antidote??
