* Add serveral options for SSD1306 integration * Add SSD1305 support (SSD1305 is similar to SSD1306, it seems SSD1305 has brightness and color register but does not have charge pump) * Add some description when manipulating registers * Add flip, offset and invert option to get more compatibility with various display modules * Fix typo `setup_ssd1036' -> `setup_ssd1306' * Add SSD1306 brightness validation tip * Add more description, limit offset range * Changes according to linter * Fix test * Raise error instead of using warning * Fix wrong logic * Remove logger Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com> * Remove logging import Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com> Co-authored-by: Jesse Hills <3060199+jesserockz@users.noreply.github.com>
