Trouble getting MatrixPortal to connect

Post by qarlwithaq »

I'm trying to get a tutorial project from Adabox 16 running but having some issues. I think it's an IO thing, but I might be wrong.

I'm following along with this guide
https://learn.adafruit.com/aio-quote-bo ... uote-board

And using this guide for the internet connection setup.
https://learn.adafruit.com/adafruit-mat ... et-connect

This is the secrets.py code I have

Code: Select all

# This file is where you keep secret settings, passwords, and tokens!
# If you put them in the code you risk committing that info or sharing it

secrets = {
    'ssid' : 'my actual wifi network name',
    'password' : 'my actual wifi network password',
    'timezone' : "America/New_York",  # http://worldtimeapi.org/timezones
    'aio_username' : 'my actual Adafruit IO username',
    'aio_key' : 'my actual Adafruit IO key',
    }
# Write your code here :-)
And then test code on the internet connect guide works fine, I see BANNED prices and a "This is a test of Adafruit WiFi! If you can read this, its working :)" message

Code: Select all

requests.set_socket(socket, esp)

if esp.status == adafruit_esp32spi.WL_IDLE_STATUS:

print("Fetching json from", JSON_URL)
r = requests.get(JSON_URL)
print("-" * 40)
print(r.json())
print("-" * 40)
r.close()

print("Done!")
And then this is the code I'm trying for my quotes:

Code: Select all

# Quote board matrix display
# uses AdafruitIO to serve up a quote text feed and color feed
# random quotes are displayed, updates periodically to look for new quotes
# avoids repeating the same quote twice in a row

import time
import random
import board
import terminalio
from adafruit_matrixportal.matrixportal import MatrixPortal

# --- Display setup ---
matrixportal = MatrixPortal(status_neopixel=board.NEOPIXEL, debug=True)

# Create a new label with the color and text selected
matrixportal.add_text(
    text_font=terminalio.FONT,
    text_position=(0, (matrixportal.graphics.display.height // 2) - 1),
    scrolling=True,
)

# Static 'Connecting' Text
matrixportal.add_text(
    text_font=terminalio.FONT,
    text_position=(2, (matrixportal.graphics.display.height // 2) - 1),
)

QUOTES_FEED = "sign-quotes.signtext"
COLORS_FEED = "sign-quotes.signcolor"
SCROLL_DELAY = 0.02
UPDATE_DELAY = 600

quotes = []
colors = []
last_color = None
last_quote = None


def update_data():
    print("Updating data from Adafruit IO")
    matrixportal.set_text("Connecting", 1)

    try:
        quotes_data = matrixportal.get_io_data(QUOTES_FEED)
        quotes.clear()
        for json_data in quotes_data:
            quotes.append(matrixportal.network.json_traverse(json_data, ["value"]))
        print(quotes)
    # pylint: disable=broad-except
    except Exception as error:
        print(error)

    try:
        color_data = matrixportal.get_io_data(COLORS_FEED)
        colors.clear()
        for json_data in color_data:
            colors.append(matrixportal.network.json_traverse(json_data, ["value"]))
        print(colors)
    # pylint: disable=broad-except
    except Exception as error:
        print(error)

    if not quotes or not colors:
        raise RuntimeError("Please add at least one quote and color to your feeds")
    matrixportal.set_text(" ", 1)


update_data()
last_update = time.monotonic()
matrixportal.set_text(" ", 1)
quote_index = None
color_index = None

while True:
    # Choose a random quote from quotes
    if len(quotes) > 1 and last_quote is not None:
        while quote_index == last_quote:
            quote_index = random.randrange(0, len(quotes))
    else:
        quote_index = random.randrange(0, len(quotes))
    last_quote = quote_index

    # Choose a random color from colors
    if len(colors) > 1 and last_color is not None:
        while color_index == last_color:
            color_index = random.randrange(0, len(colors))
    else:
        color_index = random.randrange(0, len(colors))
    last_color = color_index

    # Set the quote text
    matrixportal.set_text(quotes[quote_index])

    # Set the text color
    matrixportal.set_text_color(colors[color_index])

    # Scroll it
    matrixportal.scroll_text(SCROLL_DELAY)

    if time.monotonic() > last_update + UPDATE_DELAY:
        update_data()
        last_update = time.monotonic()
And in the terminal/serial monitor of Mu, I get the following message after saving the code and resetting:

Code: Select all

Feed key must contain lower case English letters, numbers, and dash.
Feed key must contain lower case English letters, numbers, and dash.
Traceback (most recent call last):
  File "code.py", line 68, in <module>
  File "code.py", line 64, in update_data
RuntimeError: Please add at least one quote and color to your feeds

Code done running.
Auto-reload is on. Simply save files over USB to run them or enter REPL to disable.

Press any key to enter the REPL. Use CTRL-D to reload.
And it looks like an obvious problem, but I followed the Adafruit IO guide to the letter, so my feed names are correctly formatted with just lowercase letters and a single dash, and I have a few quotes and a few colors. I've triple-checked that my IO username and key are correct, and that everything is set up properly on my IO page, and it still isn't working.

Please upgrade your CircuitPython Adafruit IO library to the latest version on: https://github.com/adafruit/Adafruit_Ci ... O/releases

We just fixed a bug which people were having with Grouped feeds.
