### API Documentation
The application programming interface html [documentation is at link](https://gavinlyonsrepo.github.io/misc/software_docs/displaylib_16bit_PICO/index.html)
hosted on github pages and generated by Doxygen. Detailed project overview images are available there.
### Fonts
The font system readme is in the 'doc' folder [at link.](extra/doc/fonts/README.md)
## Software
### 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.
It is ON by default.
If you don't want these 'advanced' functions and want to save memory space: Simply
comment out line 19 #define ADVANCED_GRAPHICS_ENABLE in displaylib_16_graphics.hpp.
This will disable advanced graphics mode. If this is disabled some examples and demos
may not work fully or even compile.
### Advanced buffer mode
Advanced buffer mode. There is advanded buffer mode where the code writes to a global screen buffer instead of the VRAM of display. It is off by default more details at readme,
which is in the 'doc' folder [at link.](extra/doc/buffer_mode/README.md)
### 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.
### 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.
### File system
Class Hierarchy:
### Error Codes
Most functions that return a value, return a enum.
Zero for success and a positive number for an error code.
Error messages are outputted to console at 38400 baud.
## Notes
### Projects using library
* [**Super-Mario-Pico**](https://github.com/tansiret/Super-Mario-Pico):
A Super Mario Bros demo game for the Raspberry Pi Pico that uses this library to drive a 16-bit TFT display.
### Older versions
* This repository before version 2.0.0 was originally
called ST7735_TFT_PICO and just supported st7735. This older version
is available in releases as 1.7.2.
