Markdown compliance & Formatting improvements

Mini12864 & MCU's improvements

Add the SCP section

Your edits are accompanied by a lot of extraneous whitespace changes. Looks like you changed the carriage return format of the files you edited. Can you fix that up, so your diffs are a little cleaner please?

[HumbleDeer]

The whitespace changes are probably intentional, depending on exactly which ones you mean. There were lots of extraneous whitespace characters that break Markdown formatting rules. There's rules on when, where, and how many. :)

No, in fact, that is not what I mean. I mean that files before you touched them are using unix line endings (LF only). After your edits, the files have mysteriously been reformatted using Windows style line endings (CRLF).

$ file sw_miniE3_v20_wiring.md 
sw_miniE3_v20_wiring.md: ASCII text

vs

$ file sw_miniE3_v20_wiring.md 
sw_miniE3_v20_wiring.md: ASCII text, with CRLF line terminators

for example.

Oh, I see! Let me check that again then. This may have been an error in the configuration of my text editor.
