Re: PyPortal Pynt User Interface example
Well, that worked... thank you very much! It's now booting properly. Now, I need to figure out how to display the data in the appropriate screen. I'll work on that this week.

Re: PyPortal Pynt User Interface example
Ok... I think I got most of it... but I've hit a bit of a wall.
First, here is the working code in it's entirety:
So, in line 163 - 166, I changed the text Label to the sensor.distance and when it boots, it does, indeed, show me a distance.
However, I want that to be updated in real time just as the data reads out in the RPEL. Anyone know how to do that?
Thanks so much!

Re: PyPortal Pynt User Interface example
Your code is too scattered to follow. The brute force insertion of multiple projects and incorrect indentation make for chaos.
You'll need to dumb it down to a few lines as possible.
Take a look at the other PyPortal examples and get your sensor input going to the display with the minimal amount of code.

I appreciate the link... But if the code is too scattered, then that would be the one who wrote the GUI ..
It is a PyPortal example.
I'm a newbie, but all I did was comment out a few blocks and inserted the Garmin LIDAR code in one place, so idk what you mean by "scattered".

Re: PyPortal Pynt User Interface example
This evening, I'll be comparing the original code to the changes I made to see if I messed up the formatting and/or errors I may have made.
Maybe some of the formatting problems are due to the copy/paste? Most of the time I use Notepad++ for that but I may have used Mu these last few times.

Re: PyPortal Pynt User Interface example
The issue here is this is too much code to work with at once. You need to walk before you can run. Simplify to getting sensor data and basic output on the TFT before trying to merge it into a massive graphical display code base.

Ah... That part is already done. The LIDAR works, I get data in a continuous stream with no issues. The problem I'm having here is that I just get the first measurement from the LIDAR on the GUI screen (I'll provide a pic later today). I want to see the continuous stream on the GUI screen.
When I replace the "sensor_data = Label(font, text=(sensor.distance,)" block with a "while True" loop, the Garmin runs with no issues in the RPEL and the Portal boots up but only shows the splash screen. My guess is that the loop is running too early in the process so it just holds at that point. I get no error messages, it just doesn't bring up the GUI.
Like I said, I'm close, just need to work out this one thing... Then I'll move on to the other integration. I really am trying to just change as little as possible and when something doesn't work, I just undo my change to revert back to the original code.

Re: PyPortal Pynt User Interface example
Looking through the code, I *think* I found the problem. I can't test it until Saturday because if I don't have the LIDAR plugged in, the code won't run.
So, I found that I had commented out line 165... probably just forgot to change it back at one point in testing.
I'm thinking that if I uncomment that line, the data should be streaming. In the original code, it was meant to be a streaming data flow. Only, I think it was using temperature or light.
Man, I hope that's it... I hate having to wait that long to test it. Grrrr! At least it's a binary and shouldn't cause any errors. At least check my logic, please. :-D

Re: PyPortal Pynt User Interface example
And I just realized that I inadvertently deleted the magic line that allows for the data to stream.
I'm working it out... My way of doing it is pretty messed up, but that's how I learn.
Code: Select all
sensor_data.text = 'Touch: {}\nLight: {}\n Temp: {:.0f}°F'.format(touch, light, tempF)

Re: PyPortal Pynt User Interface example
Okay, I figured it out!
In the Code Loop section, I just changed that to the following:
It was easier than I was making it out to be. But hey, my methods may be brute force, but that is how I learn.
Now on to the Adafruit IO integration. I anticipate a slightly easier path since I'm wrapping my head around how this code works. Well, I say that, but we'll see. :-)

Re: PyPortal Pynt User Interface example
Alrighty then... I am using the following code to integrate with with User Interface example. It works on its own and I am slowly inserting lines of code until I hit an error.
Here's the AdafruitIO example in full (working):
And here is the Original UI code (working):
I've confirmed that the import library files are no issue.
Then I inserted the try statement from the AdafruitIO below the try statement into the UI code... so, it looks like this:
That works.
However. when I paste in the following lines:
I get the following error:
Traceback (most recent call last):
File "code.py", line 67, in <module>
File "adafruit_pyportal/__init__.py", line 152, in __init__
File "adafruit_pyportal/network.py", line 90, in __init__
File "adafruit_pyportal/wifi.py", line 67, in __init__
ValueError: ESP_BUSY in use
And if I add the lines (I did this in case those previous lines refer to the following):
I get the following error:
Traceback (most recent call last):
File "code.py", line 70, in <module>
File "adafruit_pyportal/__init__.py", line 139, in __init__
ValueError: SCK in use
So, I am guessing that the ESP_BUSY is reffering to the screen being used... but that is just a guess on my part.
Can someone confirm this and is there a solution to get around this? Thanks!

Then I inserted the try statement from the AdafruitIO
Code: Select all
try:
from secrets import secrets
except ImportError:
print("WiFi secrets are kept in secrets.py, please add them there!")
raise
Code: Select all
# ------------- Inputs and Outputs Setup ------------- #
try: # attempt to init. the temperature sensor
i2c_bus = busio.I2C(board.SCL, board.SDA)
adt = adafruit_adt7410.ADT7410(i2c_bus, address=0x48)
adt.high_resolution = True
except ValueError:
# Did not find ADT7410. Probably running on Titano or Pynt
adt = None
try:
from secrets import secrets
except ImportError:
print("WiFi secrets are kept in secrets.py, please add them there!")
raise
However. when I paste in the following lines:
Code: Select all
# If you are using a board with pre-defined ESP32 Pins:
esp32_cs = DigitalInOut(board.ESP_CS)
esp32_ready = DigitalInOut(board.ESP_BUSY)
esp32_reset = DigitalInOut(board.ESP_RESET)
Traceback (most recent call last):
File "code.py", line 67, in <module>
File "adafruit_pyportal/__init__.py", line 152, in __init__
File "adafruit_pyportal/network.py", line 90, in __init__
File "adafruit_pyportal/wifi.py", line 67, in __init__
ValueError: ESP_BUSY in use
And if I add the lines (I did this in case those previous lines refer to the following):
Code: Select all
spi = busio.SPI(board.SCK, board.MOSI, board.MISO)
esp = adafruit_esp32spi.ESP_SPIcontrol(spi, esp32_cs, esp32_ready, esp32_reset)
Traceback (most recent call last):
File "code.py", line 70, in <module>
File "adafruit_pyportal/__init__.py", line 139, in __init__
ValueError: SCK in use
So, I am guessing that the ESP_BUSY is reffering to the screen being used... but that is just a guess on my part.
Can someone confirm this and is there a solution to get around this? Thanks!

Re: PyPortal Pynt User Interface example
The SPI code with ESP32 pins is already defined in your AIO code example. The error you are getting about ESP_BUSY in use is due to you already having that exact code in place.
Please be positive and constructive with your questions and comments.
