API Documentation

The application programming interface html documentation is at link hosted on github pages and generated by Doxygen. Detailed project overview images are available there.

Fonts

The font system readme for the graphic displays is in the 'doc' folder at link.

Software

Test

There are multiple examples for each device, User picks the one they want by editing the: CMakeLists.txt :: add_executable(${PROJECT_NAME} section. Comment in one path and one path ONLY. See displays readme's for more details.

Advanced Graphics

There is an advanced graphics modes in library. Standard graphics supports drawing lines, pixels
rectangles, triangles, circles and rounded rectangles. Advanced graphics supports drawing polygons, dot grid, quadrilaterals, arcs, ellipses and lines at an angle. If you don't want these 'advanced' functions and want to save memory space: Simply comment out line 14 #define ADVANCED_GRAPHICS_ENABLE in display_graphics.hpp. This will disable advanced graphics mode.

Print

The print class can print integers, floats, characters, character arrays and C++ std::strings. It can also format floating point numbers to a number of decimal places. and format integers in different base number systems. Support for other data types can be added.

Error Codes

Notes

Older versions

• This repo before version 2.0.0 was originally called SSD1306_OLED_PICO and just supported ssd1306.
