####Operate a display with ucglib
Ucglib is a graphics library with support for color TFT displays.
Ucglib v1.3.3
#####SPI connection
The HSPI module is used, so certain pins are fixed:
* HSPI CLK = GPIO14
* HSPI MOSI = GPIO13
* HSPI MISO = GPIO12 (not used)
All other pins can be assigned to any available GPIO:
* CS
* D/C
* RES (optional for some displays)
Also refer to the initialization sequence eg in [GraphicsTest.lua](lua_examples/ucglib/GraphicsRest.lua):
```lua
spi.setup(1, spi.MASTER, spi.CPOL_LOW, spi.CPHA_LOW, spi.DATABITS_8, 0)
```
#####Library usage
The Lua bindings for this library closely follow ucglib's object oriented C++ API. Based on the ucg class, you create an object for your display type.
ILI9341 via SPI:
```lua
cs = 8 -- GPIO15, pull-down 10k to GND
dc = 4 -- GPIO2
res = 0 -- GPIO16, RES is optional YMMV
disp = ucg.ili9341_18x240x320_hw_spi(cs, dc, res)
```
This object provides all of ucglib's methods to control the display.
Again, refer to [GraphicsTest.lua](lua_examples/ucglib/GraphicsTest.lua) to get an impression how this is achieved with Lua code. Visit the [ucglib homepage](https://github.com/olikraus/ucglib) for technical details.
#####Displays
To get access to the display constructors, add the desired entries to the display table in [app/include/ucg_config.h](app/include/ucg_config.h):
```c
#define UCG_DISPLAY_TABLE \
UCG_DISPLAY_TABLE_ENTRY(ili9341_18x240x320_hw_spi, ucg_dev_ili9341_18x240x320, ucg_ext_ili9341_18) \
UCG_DISPLAY_TABLE_ENTRY(st7735_18x128x160_hw_spi, ucg_dev_st7735_18x128x160, ucg_ext_st7735_18) \
```
#####Fonts
ucglib comes with a wide range of fonts for small displays. Since they need to be compiled into the firmware image, you'd need to include them in [app/include/ucg_config.h](app/include/ucg_config.h) and recompile. Simply add the desired fonts to the font table:
```c
#define UCG_FONT_TABLE \
UCG_FONT_TABLE_ENTRY(font_7x13B_tr) \
UCG_FONT_TABLE_ENTRY(font_helvB12_hr) \
UCG_FONT_TABLE_ENTRY(font_helvB18_hr) \
UCG_FONT_TABLE_ENTRY(font_ncenR12_tr) \
UCG_FONT_TABLE_ENTRY(font_ncenR14_hr)
```
They'll be available as `ucg.<font_name>` in Lua.
