I am a Noob, whith no CS background, i started copying and pasting sketches. Now i am studying C language with "Beginning C for Arduino" By Jack Purdum to get some theory.
I am trìying to understand how SD works (particularly using the sdfat library that is the best for arduino).
I found a lot of fragmentated examples, but not a good explanation of how the process works:
- Arduino SD Reference
- The library example for a low latency log (very hard to understand for a beginner, it uses binary data and i found hard to modify without a solid knwoledge)
- I also reading Sdfat.h
My goal is to undestand - How the microcontroller write the information from a sensor to a sd works.
- KPI of the process (Latency, Speed) and how to measure this metrics
- What can influence the SD writing process(dimension of the buffer) (string instead of binary informations)
What good resources, youtube videos or link to posts can you suggest for a deeper knwoledge of this subject?
Thanks in advance!
