Original description

What change would like to see?
I noticed that the Liquid Crystal library is performing amazing delays of thousands microseconds instead of reading the busy flag. Why don't we use the busy flag, which was especially buit for this usage?

Why?
A lot of time is lost because of active waits.

Would this cause any incompatibilities with previous versions? If so, how
can these be mitigated?
Not any incompatibility with previous versions.
