libssd1306's Issues

Compile without cmake

Hi,
thanks a lot for you lib, it is realy useful. I'm using it with a diy usb to i2c adapter and the example
programms are working fine!
But how can I compile my own programms without using cmake.
my g++ command looks like.
g++ my_test_oled.cxx -o my_test_oled -I /home/eagle/Downloads/libSSD1306-master/lib/
but i can not compile it succesfully and i can not extract the right arguments from the makefile.
Can you help me?

clear/update display before turn on?

Is anyone else is out there observing a short period after power up & initialization during which the display has random pixels set? Below is a fix for that (also need to remove const qualifier from init function).

// These seemed to be missing from the init sequence.
// We were seeing a brief 'starfield' on the display without them,
// presumably because the display ram isn't cleared by h/w reset
clear();
displayUpdate();

// Display On - AFh

sendCommand(OLED_SET_DISPLAY_ON);
