GDEY075Z08 DriverWhat's thisI was doing some hobby project when I found that
my newly bought e-ink display has no driver implemented
in python, which is the best choice for me to accomplish
the projectPINsTo use this library, you have to follow some hard-coded rules,
which I know is not good, but I'm too lazy to improve+-----+-----+---------+------+---+---Pi 3---+---+------+---------+-----+-----+
