Interstate75 Class
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=
DISPLAY_INTERSTATE75_32X32
DISPLAY_INTERSTATE75_64X32
DISPLAY_INTERSTATE75_96X32
DISPLAY_INTERSTATE75_128X32
DISPLAY_INTERSTATE75_64X64
DISPLAY_INTERSTATE75_128X64
DISPLAY_INTERSTATE75_192X64
DISPLAY_INTERSTATE75_256X64
You are able to set which version of the Interstate75 that you are using with the interstate75w=
. By default this value is set to True
to use the Interstate75W button layout. By setting it to False
the module will use the Interstate75 button layout. If you are using an Interstate75W it is important to set this value to interstate75w=True, otherwise this could disable the WiFi in your project
import interstate75
display = interstate75.DISPLAY_INTERSTATE75_32X32
board = interstate75.Interstate75(display=display)
Or for an Interstate75W.
import interstate75
display = interstate75.DISPLAY_INTERSTATE75_32X32
board = interstate75.Interstate75(display=display, interstate75w=False) #This is th e setup to be able to access the both A and BOOT on the Interstate75 (non W)
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.
To read a specific input, the interstate75
module contains these handy constants:
SWITCH_A
=0
SWITCH_B
=1
The Interstate75 (non W) uses the boot button instead of SWITCH_B
SWITCH_A
=0
SWITCH_BOOT
=1
if board.switch_pressed(SWITCH_A):
# Do something interesting here!
# Either for Interstate 75W
if board.switch_pressed(SWITCH_B):
# Do something else even more interesting here!
# Or for Interstate 75
if board.switch_pressed(SWITCH_BOOT):
# Do something else even more interesting here!
RGB LED
The Interstate has an RGB LED. This is accessed via the following method.
.set_led(r, g, b)
Where r, g, b are values between 0 and 255
example:
board.set_led(255, 0, 0) # Makes the LED Red
board.set_led(0, 255, 0) # Makes the LED Blue
board.set_led(0, 0, 255) # Makes the LED Green
Display
The display is all handled by our custom picographics drivers they can be accessed via .display
.
example:
display = board.display
display.text("Hello World!", 0, 0)
display.line(0, 0, 128, 64)
board.update() # Update display with the above items
