Check this branch out: https://github.com/espruino/Espruino/compare/direct_io
Not tested on anything yet, but hopefully that'll make
shiftOutsignificantly faster on all the main platforms (not ESP8266, but presumably direct IO could be added there too).I was wrong about software SPI being improved, but that could be improved in the same way now without having to add anything platform specific.
