## GFX Pack Class
|
|
|
|
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
|
|
|
|
``` |
