RuntimeError: Invalid font File #39

Closed ManicalEngineer closed 4 years ago

ManicalEngineer commented 4 years ago

I got the following when trying to run the rfm9x_check.py code provided on the adafruit website. Any help would be great

Traceback (most recent call last): File "radio.py", line 39, in display.text('RFM9x: Detected', 0, 0, 1) File "/usr/local/lib/python3.5/dist-packages/adafruit_framebuf.py", line 415, in text self._font = BitmapFont(font_name) File "/usr/local/lib/python3.5/dist-packages/adafruit_framebuf.py", line 494, in init raise RuntimeError("Invalid font file: " + font_name) RuntimeError: Invalid font file: font5x8.bin

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "radio.py", line 40, in except RunTimeError as error: NameError: name 'RunTimeError' is not defined

look here https://github.com/adafruit/Adafruit_CircuitPython_framebuf/tree/master/examples

This wasn't a matter of being able to find it. I've downloaded that file and it did not solve the issue, it seems that this is critical to getting the rfm9x boards to run

@ManicalEngineer can you post a link to the guide page that you are working from?

At least one of the issues seems to be that somewhere you've got code with RunTimeError in it, note the capital T whereas python is expecting RuntimeError

What kind of environment are you attempting to run this on? I see python3.5 folder so I assume something like Raspberry Pi, is that right?

ladyada commented 4 years ago

the font file needs to be in the same folder as the script you are running plz see instructions here! https://learn.adafruit.com/lora-and-lorawan-radio-for-raspberry-pi/rfm9x-raspberry-pi-setup#installing-circuitpython-libraries-3013548-2

@FoamyGuy thanks for pointing that out - fixed that and re-ran that the script, got the following: Traceback (most recent call last): File "radio.py", line 39, in display.text('RFM9x: Detected', 0, 0, 1) File "/usr/local/lib/python3.5/dist-packages/adafruit_framebuf.py", line 415, in text self._font = BitmapFont(font_name) File "/usr/local/lib/python3.5/dist-packages/adafruit_framebuf.py", line 494, in init raise RuntimeError("Invalid font file: " + font_name) RuntimeError: Invalid font file: font5x8.bin

During handling of the above exception, another exception occurred:

@ladyada it is in the same folder (see output from ls -l below)

the font file size is not correct, check you are downloading it properly

ManicalEngineer commented 4 years ago

how do I download it correctly? I've been using wget

ladyada commented 4 years ago

we downloaded it from https://github.com/adafruit/Adafruit_CircuitPython_framebuf/blob/master/examples/font5x8.bin

with image

you could also try wget https://github.com/adafruit/Adafruit_CircuitPython_framebuf/raw/master/examples/font5x8.bin but we did not test it

ManicalEngineer commented 4 years ago

I did wget https://github.com/adafruit/Adafruit_CircuitPython_framebuf/raw/master/examples/font5x8.bin and it worked this time. However I did try wget from the other address provided and it did not.

Thank you for helping resolve this
