CubeSat — ConnectEd Code

Workbook 1 - Introduction to Kookaberry

Parts 1-4
(print, display, variables, buttons, while loops)

# This is a comment
from connectedcode import *

# Print to the console
print("Hello world")

# Print to the console using a variable
name = "Jack"
print(name)
print("Hello", name)

# Print to the Kookaberry display
display.print("Kookaberry")
display.print("Hello", name)

# Print to a specific position on the Kookaberry display
display.print_at_position(2, 7, "bottom text")
display.print_at_position(2, 7, "lower words")

# Flash each LED for a second.
led_green.on()
sleep(1)
led_green.off()
led_orange.on()
sleep(1)
led_orange.off()
led_red.on()
sleep(1)
led_red.off()

# Loop forever
while True:
    # Print hello, then sleep for a second.
    display.print("Hello")
    sleep(1)

    # Check if button A was pressed
    if button_a.was_pressed():
        # if it was, say that, then wait for a second.
        display.print("Button A was pressed")
        sleep(1)
    else:
        # Otherwise, clear the display.
        display.clear()

Parts 5 - repeat after me
(combine previous concepts + for loops)

from connectedcode import *

# Create the presses as an empty string
presses = ""

# Loop forever
while True:
    # Check if each button was pressed
    # And add the matching letter to the presses string
    if button_a.was_pressed():
        presses = presses + "a"
    if button_b.was_pressed():
        presses = presses + "b"
    if button_d.was_pressed():
        presses = presses + "c"

    # Clear the display, then show the new presses
    display.clear()
    display.print(presses)

    # Once button C is pressed...
    if button_c.was_pressed():
        # Loop through each letter in presses
        for letter in presses:
            # Flash the matching LED for half a second
            if letter == "a":
                led_red.on()
                sleep(0.5)
                led_red.off()
            if letter == "b":
                led_green.on()
                sleep(0.5)
                led_green.off()
            if letter == "d":
                led_orange.on()
                sleep(0.5)
                led_orange.off()
        # Reset presses to empty, to reset the game.
        presses = ""

Workbook 2 - Radio

(Set up radio, send & receive messages)

from connectedcode import *

# Store your team name in the variable called channel
channel = "Team_Renee_and_Jack"

# Set up radio and set the correct channel
radio = connect_radio()
radio.set_channel(channel)

# Send a message over the radio
radio.send_message("Hello")

# Continually check for new radio messages
# If there is a message print it out.
while True:
    message = radio.get_message()
    if message:
        display.print(message)

Workbook 3 - Sensors

(set up sensors, calibrate, take measurements)

from connectedcode import *

# Set up and calibrate sensors
cubesat_sensors = connect_sensors()
cubesat_sensors.calibrate()

# Make your program run continuously
while True:
    # Take measurements and store them in variables
    altitude = cubesat_sensors.get_altitude()
    temp = cubesat_sensors.get_temperature()
    pressure = cubesat_sensors.get_pressure()
    acceleration = cubesat_sensors.get_acceleration()

    # Display your measurements on the screen
    display.print(f'Altitude: {altitude} m')
    display.print(f'Temp: {temp} c')
    display.print(f'Press: {pressure} hPa')
    display.print(f'Accel: {acceleration} g')

    sleep(0.5)

Workbook 4 - Logging & Graphing

(set up sensors, calibrate, take measurements)

from connectedcode import *

# Create a variables to store your team name and the headers for your file
team_name = "Team_Renee_and_Jack"
headers = "time,altitude"
# Use the header variable to start the logger
logger = start_logger(team_name, headers)


# Set up and calibrate the sensors
cubesat_sensors = connect_sensors()
cubesat_sensors.calibrate()

# The main code loop where altitude measurements will be logged every second
while True:
    # Measure the altitude
    altitude = cubesat_sensors.get_altitude()

    # get and print the time
    current_time = seconds_since_start()
    display.print(f"Time: {current_time} sec")

    # print the altitude
    display.print(f"Alt: {altitude} m")

    # Create a variable that stores the data, formatted correctly for logging. Then log the data. 
    data = f"{current_time},{altitude}"
    logger.log(data) 

    # Keep checking the time every 0.1 seocnds (in another while loop) 
    # until 1 second has passed since the last time current_time was set
    while seconds_since_start() == current_time:
        sleep(0.1)

    display.clear()
