PyPortal: Astronomy NASA: Network Error

by fhayes on Tue Nov 16, 2021 7:39 pm

Receiving HTTP 422 error trying to load NASA Astronomy image of the day. The output text is below.
Am I makinng an obvious error?

PyPortal
Circuit Python 7.0.0
Library Bundle: adafruit-circuitpython-bundle-7.x-mpy-20211116

I followed the learn guidelines and validated that the NASA image exists and loaded. I successfully tested ESP32 WiFi connectivity to my home network.

Repl Output (I did edit to delete the AIO Key)

New Day; different error. I have not changed the code; simply brought in the library and code.py from the learn guideline.
Still failing on line 29 in code.py
response = pyportal.fetch()

PyPortal NASA Image Viewer still does not work correctly.

I downgraded the NASA program on Pyportal to CP 6.3.0. I am Still seeing an error somewhere within pyportal.fetch(). Error output for CP 6.3.0 is the same as CP 7.0.0.
In adafruit_bitmap_font/pdf.py line 75 is where the fault occurs and this has something to do with parsing through fonts/Arial-12.bdf.
line 75: self.file.readline()
I tried to remove that code section as an error source by substituting a modified bdf.py for bdf.mpy. I examined Arial-12.bdf and manually set the values for self._ascent = 11 and self._descent = 2 in bdf.py.
_____________________________________________________________
def ascent(self):
"""The number of pixels above the baseline of a typical ascender"""
if self._ascent is None:
self.file.seek(0)
self._ascent = 11
# while True:
# line = self.file.readline()
# line = str(line, "utf-8")
# if not line:
# break

# if line.startswith("FONT_ASCENT "):
# self._ascent = int(line.split()[1])
# break

return self._ascent
______________________________________________________

But this did not solve the issue - I just got another error on bdf.py/line ~144 also seemed to fail on a call to self.file.readline(). This was in a call to load_glyphs(self, code_points)

PyPortal: NASA Daily Image - still not working.
I've experimented with CP 6.3 and 7.0 without success. From long experience in computer programming, I am operating on the assumption that the issue is something I have done wrong. Nonetheless, no further progress. I created a minimally viable program which failed if I included a specification for the font in the instantiation of PyPortal object.

cwd = ("/"+__file__).rsplit('/', 1)[0] # the current working directory (where this file is)
strText_Font = (cwd + "/fonts/Arial-12.bdf")
print("font = ", strText_Font)
# create pyportal object w no data source )
pyportal = PyPortal (
url = None,
json_path = None,
status_neopixel = board.NEOPIXEL,
default_bg = None,
text_position = (30,120),
text_font = strText_Font,
text_color= 0x00ff00
)
print("just past instatiation of pyportal")
i = 0
while True:
pyportal.text_position = (10, 10)
pyportal.set_text("How Now Ecru Bovine ", i)
i=i+1
time.sleep(5)

Are you using latest library versions taken from downloaded bundle?

Thank you for responding.

I have tried things with CP version 6.3 and 7.0. I've used the CP bundle from CircuitPython.org _and_ used the zipped files from the learn guide. In all four cases -> an error occurs in adafruit_bitmap_font/bdf.mpy. I reproduced the error with three different learn guidleines as well as PyPortal and PyPortal Titan devices.

adafruit-circuitpython-bundle-6.x-mpy-20211118
adafruit-circuitpython-bundle-py-20211118 i downloaded this to view adafruit_bitmap_font/bdf.py
adafruit-circuitpython-bundle-7.x-mpy-20211117

Did you do the changes needed for setting up boot.py?

Yes, changes made to boot. I get a warning message when the device powers up. I'm going go through a complete systematic build (zero out the files first) of the learning guide.

I just tested the NASA Image of the Day code on a PyPortal running Circuit Python 7.0.0:
https://learn.adafruit.com/pyportal-nas ... age-viewer
and it ran OK. So everything should work as shown.

One thing to try is grabbing the code and assets all together via the Project Bundle:
bundle.jpg
bundle.jpg (29.07 KiB) Viewed 594 times

That will give you a .zip file with everything you need in one place.
