This library offers convenient functions for interacting with [Pico GFX Pack](https://shop.pimoroni.com/products/gfxpack) - The Pico GFX Pack adds a 128x64 LCD Matrix display to your headered Raspberry Pi Pico or PicoW, with RGBW backlight and 5 input buttons for all your display anc control needs.
The `GfxPack` class deals with RGB backlight and buttons on the GFX Pack. To create one, import the `gfx_pack` module, then define a new `board` variable:
```python
import gfx_pack
board = gfx_pack.GfxPack()
```
### Switches
The GFX Pack has 5 user switchs located just under the display labeled A to E. The names of these switches in the class are:
`.switch_a`
`.switch_b`
`.switch_c`
`.switch_d`
`.switch_e`
These can be read with the `.is_pressed` method.
```python
if (board.switch_a.is_pressed):
print('You pressed Switch A')
if (board.switch_b.is_pressed):
print('You pressed Switch B')
```
### RGB Backlight
The GFX has an RGB backlight as well as the regular Matrix display backlight to change the colour of the backlight. This is accessed via the following method.
`.rgb.set_rgb(r, g, b)`
Where r, g, b are values between 0 and 255
example:
```python
board.rgb.set_rgb(255, 0, 0) # Makes the Backlight Red
board.rgb.set_rgb(0, 255, 0) # Makes the Backlight Blue
board.rgb.set_rgb(0, 0, 255) # Makes the Backlight Green
