pimoroni / scroll-phat Goto Github PK

Hey guys,

Great little display! I was trying to figure out how to change the font. I can see there is a font.png in the repo, and i have changed this, but can't figure out where it is stored in the pi system, and have done a find to look for it, and still no luck. Does this PNG get converted into something else?

Cheers
Rob

I'm looking at the following (work in progress):

• Remove all comments from Dockerfile (the docker.md file is enough, will be renamed readme.md)
• Refactor the Dockerfile to make it a single layer and easier to pull/extract on the Zero.
• Make mention of i2c on host in readme.md

Re comment by @dfranssen to include all dependencies for examples in Dockerfile I don't think this approach is ideal. The Dockerfile should be lean and these can be added separately later. The examples already have good checking for libraries present.

Adding a library is normally as simple as something like:

FROM alexellis2/scroll-phat
RUN pip install numpy

I would still like to promote the Dockerfile to the top level of the repo to make it easier to use and less surprising. Check out a few open source projects (you'll see that's where the file sits)

@RogueM @Gadgetoid anything else?

I was going to have a look at optionally flipping the font because the HAT + PI would probably self-balance better if upside down with cables etc coming out the top. Where you would suggest starting?

Would an image rotate and flip transform work in the load_font method?

so when i run the example files from idle 2.7 it comes back with 2 errors here is a screen shot please could someone tell me how to fix it.

Just trying to get me scroll pHat working and getting the following error.
pi@raspberrypi:~/dev/scroll-phat $ python test-all.py
Traceback (most recent call last):

I will continue poking around, but it would be nice if it was not quite so dark in this corner :-)

Works under python[2].

Here are the error logs.

Plz consider adding a auto_scroll variable or a .scroll_string function that pass the message for one time automatically.

Trying to get scrollphat up and running (on the AIY image) using both the Pimoroni dashboard and the Bash script, but whilst both work in Python2, when attempting to run in Python3 I received, ImportError: No module named 'scrollphat'. To get it working under Python3, I had to clone the repo and do, sudo python3 setup.py install. Not sure if this is a weird issue with the AIY image, or a general issue.

I have no idea how Fahrenheit works. The localweather.py however, display temperatures in the unit almost only used in US.

pi@raspberrypi:~/Pimoroni/scrollphat/examples $ python3 localweather.py 
Location: Vienna, AT
 Sat: Showers - L: 35F - H: 57F Sun: Rain - L: 41F - H: 51F

Some wait to get Centigrade by default or change with local settings?

Just installed the latest jessie lite, did update and upgrade and on install (curl -sSL get.pimoroni.com/scrollphat | bash) I found myself stuck after:

Sorry, Apt failed to install python3-pip, I can't continue!

sudo apt-get -f install seemed to fix it by installing libpython3.4-dev

In general and in the sine.py example am getting AttributeError: 'module' object has no attribute 'set_buffer'

New to this so might be me - otherwise scrollphat is superb and all other examples working - including the excellent weather parser

Hi there, newbie here, so apologies upfront!
I can successfully run most of the scroll-phat examples, but not the text scroll ones. When I run them, i get no output on the scroll-phat - are they waiting for me to enter some text?

If so, if I enter (eg) Hello World, I get the following error:-
usage: python simple-text-scroll-rotated.py "message"
press CTRL-C to exit

hello world
SyntaxError: invalid syntax
hello
Traceback (most recent call last):
File "<pyshell#2>", line 1, in
hello
NameError: name 'hello' is not defined

KeyboardInterrupt

If I then enter "Hello World" ie with quotation marks I get:-

================================ RESTART ================================

usage: python simple-text-scroll-rotated.py "message"
press CTRL-C to exit

"hello world"
'hello world'

But still no output on the Scroll-Phat itself...

Can anyone suggest what I'm doing wrong?

Thanks

When I use the command "sudo apt-get install pimoroni" it just says "E: Unable to locate package pimoroni-dashboard"?
When I try the manual version its installing but when i try to execute one example it has a lot of errors

I am getting an error for both python3 and python2 with raspberry pi 0 and 3

I have tried installing from the git repo and enabled i2c.

i2c doesnt put out anything that is out of the ordinary

I am on retropie. I have tried it on multiple versions of retropie.

the one liner bash script doesnt work. I tried that first.

I am trying to use a scrollphat.

Here is the error:

Traceback (most recent call last):
  File "test-graph.py", line 5, in <module>
    import scrollphat
  File "/usr/lib/python3/dist-packages/scrollphat/__init__.py", line 20, in <module>

OSError: [Errno 5] Input/output error

Just got this up and running. I've suggest tweaking the instructions to include that a Reboot is required.
I guess this may not be needed if I2C was previously enabled, but on a new Pi Zero (fresh, updated image) I did need to re-boot. Some users may need a hand.

Also it may help newbies to know they need to navigate to the python scripts and how to run them;

cd Pimorino/scrollphat/
python ip.py

(etc).

A nice big of work - well done :-)

I'm seeing odd behaviour when passing a list of integer values rather than floats. With ints, all of the columns seem to scale to the max. If you convert the ints to floats, it behaves as expected.

Hi, looks like the BBC Weather RSS feed has changed:
https://www.bbc.com/weather/about/17543675
Example:
https://weather-broker-cdn.api.bbci.co.uk/en/forecast/rss/3day/s2
Changed line 31 to:
url = "https://weather-broker-cdn.api.bbci.co.uk/en/forecast/rss/3day/" + postcode
and all is good

the sine.py shows IP address and CPU usage, because the second WHILE loop won’t be run.
I suggest to rename the example and spilt it to two example files.

A minor thing. When running the examples, it throws an error about not being able to find the font file.

Moving library/font.png to the examples folder fixes this.

Great module though, I love it!

The current installation works by downloading and running several shell scripts over a completely unauthenticated connection which makes it very easy for an attacker to serve malicious scripts instead. This poses a huge security and privacy risk to your users, especially considering some of the scripts are expected to be ran with sudo!

Please fix this by adding certificate(s) to your server(s), updating your scripts to authenticate the server connection and updating your installation instructions (e.g. tell users to use curl with the --cacert option or tell them to check the first script they download and use the option in there).

Hello,

I am trying to use localweather.py but I have an error message.

Location: Le Vésinet, FR Traceback (most recent call last): File "localweather.py", line 68, in <module> weather = get_weather(location_string) File "localweather.py", line 41, in get_weather uri = base + encode(qs) File "localweather.py", line 33, in encode val = urllib.parse.urlencode(qs).replace("+", "%20") AttributeError: 'module' object has no attribute 'parse'

At first I was thinking the issue could come from the city name that has an "é" but then I had a look at the code and saw that it was using yahooapis.com which has been killed in 2017 apparently.

I'm very new to python so I can barely read what the script does. Is there a possibility to set the location manually ? Or to use something like openweathermap ? With possibly manual input to improve accuracy when using a pi that doesn't travel much.

Thank you very much for the examples provided with the pHAT and also for your time

I just received my Raspberry Pi Zero W Scroll Bot project and got everything setup, however, I'm getting a problem when trying to run any of the examples or simply the scrollphat module at all:

I've checked and I2C is enabled but, I'll admit, this was the first time that I've soldered on a circuit, so I'm not sure if it's gone wrong there. The solder joints look good to me though. Any input on this error or advice as to whether it could be related to bad soldering would be greatly appreciated. Is it possible to diagnose the GPIO connection to test that it's all good or, even better, detect any errors on individual connections?

Again, I'll admit this is my first time really working with GPIO so please excuse my ignorance, but here's the output of running i2cdetect in case it helps at all:

pi@raspberrypi:~/Pimoroni/scrollphat $ i2cdetect -y 1

Just got my Pi Zero with the Scroll PHat, everything installed fine and I ran a few of the example scripts. But when I execute the 'turn-leds-off.py' script nothing happens. With Some of the examples the LEDs turn off for a fraction of a second, but they turn back on and the example carries on running, just flashing the LEDs off and on in effect.

Please help, I have to reboot every time I want to turn the LEDs off.

Cheers.

Hi... I bought this item from you at PiWars and you said to let you know if there were any issues. It's all soldered up now and connected but the software would not install for me. Please advise.
