OLED Character display - Some commands don't work

    The display is HD44780 compatible, however there are some minor timing differences that sometimes need to be accounted for (depending on your micro).  I have replicated this with an Arduino, and have found that the busy flag will 'hang' after the clear display command if there is not a delay present after the command is sent (and before the busy flag is checked).  Please add a 2ms delay after sending this these commands, as this fixed the issue for me.
