I am using oled-i2c-bus to display an interactive menu on a SSD1306 0.96 128x64 OLED display attached to a Raspberry Pi Zero. The library works very well except for a few design flaws that can be easily corrected. The most important one is the display speed. By using _transfer function, the payload is segmented into individual bytes that are send each in a separate transaction. These transactions add the data byte (0x40) before the payload byte thus doubling the throughput. This has the unpleasant effect of one actually seeing the screen as it slowly refreshes. However, the payload bytes can also be sent in a burst, with a single leading data byte 0x40, bypassing _transfer function altogether and writing directly to i2c. Therefore the update time is halved. This doesn't sound as much in theory but in practice is a huge improvement as the eye sees an almost instant update as opposed to a slooooow refresh. Another improvement would be the actual clearDisplay function which is very complicated and slow. A clear display action should simply fill the buffer with 0x00 and if required, update the display.
Speed up page update on display and page clear
Added drawRGBAImage() method with examples and documentation.
fillRect specifies width and height not lower right coordinates
readme update
Avoid ENOENT exception due to missing I2C bus. Add a variable for setting the I2C bus, by default 1 as this is vaild for newer Raspberry Pi versions. On other platforms the value might be different, for example 0. Tested on Raspberry Pi 4 Model B. Signed-off-by: Leon Anavi <leon@anavi.org>

so that it works on the first time!

This change is backward compatible with the 1.0.11 version. I recently have constructed additional oled fonts from a site I found that had character sizes > 8 pixels. These fonts are useful for displays that are larger than 128x32 such as 128x64 or 128x128. I plan to add these fonts in the very near future to npm but before I do, I need a module that will support them. The current oled font character structure is such that each element in the array is a represents a column and bit values of the byte represent rows in the column. The current code supports font with character widths larger than 8 pixels but it does not support fonts with character heights larger than 8 pixels. This update includes a minor fix to word wrap (should no wrap the first word) and the changes to support fonts with character height larger than 8 pixels. Version number bumped to 1.0.12.
Enhancement to add support for larger fonts.
- restructure the code to accomodate swappable drivers - add a few of new APIs to draw an interactive and indicators icons * battery * bluetooth * wifi * image (a wrapper for `drawRGBAImage`) + add some "png" files for icons, numbers and logos - use `oled-font-pack` in examples and tests - allow errors to bubble up * except for `_waitUntilReady` function which might cause uncaught exception - bump package version to 1.1.0 - update readme to include instructions on enabling software I2C and the new APIs
feature: add support for sh1106
