initializing oled display using vhdl

What about doing a simulation of that design and analyze its behaviour? 
The only thing your testbench must supply is a clock and the reset.

By looking at the code i see something like that:

1

    if rising_edge(clk) and cnt < 1000000 then

2

      cnt <= cnt + 1;

3

    elsif rising_edge(clk) and cnt = 1000000 then

And by seeing that I urge you to take that display control code more as 
a "how-not-to" example...

Thats obviously a straight forward HD44780 compatible interface. You can 
find lots of code for controlling such displays.
By comparing the simulation results to the data sheet I see some 
potential to improve timings...


BTW: when attaching *.vhdl files instead of *.txt files some kind of 
magic named "syntax highlighting" happens.
