The `Interstate75` class deals with RGB LED and buttons on the Interstate75 and 75W. To create one, import the `interstate75` module, then define a new `board` variable.
|
||||
|
||||
This is where you define the HUB75 matrix display size that you wish to use by defining `display=`
|
||||
|
||||
```python
|
||||
import interstate75
|
||||
|
||||
display = interstate75.DISPLAY_INTERSTATE75_32X32
|
||||
|
||||
board = interstate75.Interstate75(display=display)
|
||||
```
|
||||
|
||||
The version of Intersate75 you're using should be automatically detected. Check `board.interstate75w` to verify this. It should be `True` on a W and `False` on a non-W.
|
||||
|
||||
You can choose the HUB75 matrix display size that you wish to use by defining `display=` as one of the following:
|
||||
|
||||
```python
|
||||
DISPLAY_INTERSTATE75_32X32

||||

display = interstate75.DISPLAY_INTERSTATE75_32X32
|
||||
|
||||
board = interstate75.Interstate75(display=display)
|
||||
```
|
||||
|
||||
From here, all features can be accessed by calling functions on `board`. In addition, when using Qwiic / Stemma QT devices, the I2C channel to use can be accessed with `board.i2c`.
|
||||
|
||||
### Switches
|
||||
|
||||
Interstate75 and 75W have two switches in the front of the board. To read one of the switches, call `.switch_pressed(switch)`, where `switch` is a value from `0` to `.NUM_SWITCHES - 1`. This returns `True` when the specified switch is pressed, and `False` otherwise.
