epd init script not working on Raspberry Pi2

[mad61]

The epd init script is not working on RPi2 (running Raspian Jessy).

After changing line 34 in epd-fuse:

34c34
<     modprobe spi-bcm2708

---
>     modprobe spi-bcm2835

everything works on RPi2 as well.

[shawaj]

We are aware of this issue and will be fixing it as soon as possible here.

Have you found any other errors with any of the Python scripts or anything?

[mad61]

I fixed the following yet.

[shawaj]

Could you try again now?

[delormev]

@mad61 is correct re: spi-bcm2835 on a Pi 2, and also in the modifications he had to make to the different python scripts! I've made the same changes and most things are working correctly now!

[shawaj]

@delormev @mad61 could you try again with the updated code?

[delormev]

@shawaj I don't think the code had been updated... The issues were still there when I checked out the code a couple of hours ago (see for example line 37 and 39 of https://github.com/PiSupply/PaPiRus/blob/master/papirus/text.py) So was the issue with edp-fuse (but I guess that's not on your side, I've also opened an issue for @repaper/gratis)

[shawaj]

@delormev - hmmm thought we had fixed all of the issues. Will take another look now. The epd-fuse one is the spi-bcm2835 one right? I can email straight to the relevant person at repaper too.

[ghost]

Hey guys - I'm getting pretty much all the same errors as above. Im running a B+ with the latest wheezy image. I can't resolve the indent issue even though I've dragged the text.py file into every editor I have. Do you have any pointers for a new install?

[sampsakuronen]

I have spent an hour debugging this. No luck so far. I'm running the newest Raspbian Jessie.

Installing libfuse-dev fails, this .deb is not found. Version deb8u2 is available here: http://mirrordirector.raspbian.org/raspbian/pool/main/f/fuse/

E: Failed to fetch http://mirrordirector.raspbian.org/raspbian/pool/main/f/fuse/libfuse-dev_2.9.3-15+deb8u1_armhf.deb  404  Not Found [IP: 5.153.225.207 80]

I tried installing that version and making everything from scratch, as stated in the Readme of this repository. The line cd /tmp/papirus/gratis-master/PlatformWithOS needs to be cd /tmp/papirus/gratis/PlatformWithOS/

After fixing the intendation and font path bugs in scripts I'm at this point:

@sampsakuronen: The no module named EPD error is because of an error in the script. There's another PR out to fix that. I was getting a 404 with the fuse install till I did a apt-get update.

[jayeshjoy]

@gaerank : For the "No module named EPD" error, try the changes listed here: https://github.com/PiSupply/PaPiRus/pull/5/files Or a simpler one line change is to change line 26 in the papiru-clock script from

from EPD import EPD

to

from papirus import Papirus as EPD

For the "No such file or directory: '/dev/epd/version'" error, try running 'sudo papirus-config' -> 'Enable Driver' -> 'Disable'

[gaerank]

Hi, First, I modified three files as your guide. I did the papirus-config enable->disable driver. yeah, the "No such file or directory..." message has gone. But I have still other errors.

Here is what I am done.

1. sudo papirus-config select display size -> 2.7
2. ls -al /dev/epd <<< can see files
3. sudo papirus-config -> enable driver.
4. ls -al /dev/epd <<< empty
5. sudo papirus-config -> disable driver.
6. ls -al /dev/epd <<< can see files
7. sudo papirus-clock
8. ls -al /dev/epd , ls -al /dev/ <<< get message "ls: cannot access epd: Transport endpoint is not connected"

hope this help to find problems.

Thank you.

Hi, Thank you for the information. First time I got the package, I have no idea with the pogo pin. Now I know what pogo pin for. So, I solder it as the link page. same step as the page but the results is same.

I don't know what's wrong on my PaPirus.

Thank you Best Regards,

Kevin.

Hello, I found something wrong. I didn't touch the button battery when I got the package. The button battery was not correctly assembled. As you know the battery is pre-assembled.

When I remove the battery, I found the +pin got bend as below picture.

Could this make my papirus defect?

[YoungAtHome]

Continuing to get ImportError: No module named epd File init.py From EPD import EPD as Papiris

When I use papirus-config to enable the driver I get an error. But it seems to be enabled on startup. Evidence is files in /dev/epd

Any suggestions welcome.

[vogonsaudi]

YoungAtHome, I followed these instructions http://frederickvandenbosch.be/?p=1483 and also created a simple, thrown together wiki up there ^^^ to show the steps I had to take to get it working.

Transport error means no SPI so neec to enable in raspi-config and reboot.

I have papirus working with python 2.7 but not 3.2.

Hi YoungAtHome, I've ran raspi-config for enable SPI.

pi@raspberrypi:~ $ sudo raspi-config 9 Advanced Options > A6 SPI > Would you like the SPI interface to be enabled? > Yes > Yes > Yes> Yes> Finish > Reboot

It is working. Thank you for share.

Here is my conclusion.

1. enable SPI by run raspi-config <<< mandatory!!!
2. Reboot
3. modify /usr/local/bin/papirus-clock
   
   • from EPD import EPD
     
   • from papirus import Papirus as EPD
4. modify /usr/local/bin/papirus-write
   
   • font = ImageFont.truetype('Pillow/Tests/fonts/FreeMono.ttf', size)
     
   • font = ImageFont.truetype('/usr/share/fonts/truetype/freefont/FreeMono.ttf', size)
     add tab below two lines each head.
     text_lines.append("")
     text_lines[current_line] += " " + word
     
5. Not sure to remove python3. I've tested remove python3 and re-installed but the python3 was not a problem.
6. run sudo papirus-clock
7. run sudo papirus-write "hello world"

Best Regards,

Kevin.

I was continuing to get the indent error in text.py after changing the code, so I cleared the python3 cache files for papirus cd /usr/local/lib/python3/dist-packages/papirus sudo find . -name '*.pyc' -delete

Rerun the clock to test. sudo papirus-clock

Regards, Nick

[scargill]

I am getting that indent error - after fixing other issues.. so right now - the clock works but keeps going backwards - and the text - I keep getting an indent control where there is no faulty indent. Can the organisation please fix the stuff out there so that instead of having to sail through forums we can just run the product and not have to get into clearing caches etc.... not really good enough though I and others are grateful to those who've taken the time to fix this stuff - we really should not have to be doing this for something as basic as getting text on a display.

[trashcan]

  File "/usr/local/lib/python2.7/dist-packages/papirus/epd.py", line 136, in display
    raise EPDError('image size mismatch')
papirus.epd.EPDError: 'image size mismatch'

What resolution should I use for the "large" display?

[YoungAtHome]

Display sizes are: Small 1.44" diagonal and 128 x 96 pixel resolution Medium 2.0" diagonal and 200 x 96 pixel resolution Large 2.7" diagonal and 264 x 176 pixel resolution

As I recall there may be a default of 2.0 (medium) in the epd.py script.

Use sudo papirus-set 2.7 or sudo papirus-config to set.

Warning: Enable and and disable driver may be swapped in config so choose and read on screen to check.

Good luck.

I have mine working on Python3.

It works so well that the whole screen went black just from running papirus-clock.

Followed all of the fixes metioned above till it started working and then after around 20 seconds the screen filled itself for some reason. papirus-clear doesn't clear the screen either. I tried running papirus-gol afterwards and the screen cleared a bit (if you can see it in the image above).

Also, why is the pogo pin needed?

[YoungAtHome]

Congratulations.

The pogo pin is a gpio connector to the reset point on the Pi so setting the papirus end of the pin triggers either a reset or start (if Pi is off). Gives wake-on-alarm but no clear documentation.

I have also got a black screen that doesn't clear. Going to try on another hat but this was my large screen. I have written code that tried to change the screen too fast and that left it black. It may be overclocking or fast pi2 that are not expected by papirus.

Need to get input from Aaron and co.

Any luck getting the screen to clear? I have noticed that if I run papirus-clock long enough and then exit it, the pixels that are left from the last digit of the seconds appear as white on the yet to reset black screen. Though during all that time running the program, the screen remains black.

Correction: I can see the pixels changing slightly to white where the seconds are being shown. It's just that after the program is closed that the pixels get clearer.

Please don't mind the dust on the screen~

[YoungAtHome]

That's interesting. I've still not cleared my large screen as I switched to using the medium one I also got. See 3D Monster Maze! I tried some drawing and partial update (and maybe full update) seem to change a whole line at a time. See large screen 2nd pic. You could use the image library to draw a white screen and then a vertical black line at various positions to see if that clears it. I also noticed that all the Pervasive demos show a full white screen then black, then white. May need to cycle the screen with sleep in between. I'll try tomorrow. Have fun.

This is was a really useful thread, thank you to everyone. http://frederickvandenbosch.be was especially great.

PI Supply were telling reviewers last year that the finished products wouldn't have these issues. That indentation bug is a sore one to miss.

[Pingk-NC]

I'm still having issues with this. So far I have...

Enable SPI interface through raspi-config

sudo apt-get install python-imaging
git clone https://github.com/PiSupply/PaPiRus.git
cd PaPiRus
sudo python3 setup.py install 

papirus-setup
papirus-set 2.0

(Note I used python3 to run setup.py) Running papirus-clock gives me:

File "/usr/local/bin/papirus-clock", line 26, in <module>
from papirus import Papirus
File "/usr/local/lib/python3.4/dist-packages/papirus/__init__.py", line 1, in <module>
from epd import EPD as Papirus
ImportError: No module named 'epd'

However changing papirus-clock to

- from papirus import Papirus
+ from papirus import Papirus as epd

Has no effect, and changing init.py to

- from epd import EPD as Papirus
+ from papirus import Papirus

Gives me the error:

File "/usr/local/bin/papirus-clock", line 26, in <module>
from papirus import Papirus# as EPD
File "/usr/local/lib/python3.4/dist-packages/papirus/__init__.py", line 2, in <module>
from papirus import Papirus
ImportError: cannot import name 'Papirus'

So the "No module named epd" error has changed to "Cannot import name Papirus". I don't understand why this doesn't work, any help would be appreciated

File "/usr/local/bin/papirus-clock", line 26, in from papirus import Papirus File "/usr/local/lib/python3.4/dist-packages/papirus/init.py", line 1, in from epd import EPD as Papirus ImportError: No module named 'epd'

However changing papirus-clock to

• from papirus import Papirus
• from papirus import Papirus as epd

Has no effect, and changing init.py to

• from epd import EPD as Papirus
• from papirus import Papirus

Gives me the error:

File "/usr/local/bin/papirus-clock", line 26, in from papirus import Papirus# as EPD File "/usr/local/lib/python3.4/dist-packages/papirus/init.py", line 2, in from papirus import Papirus ImportError: cannot import name 'Papirus'

So the "No module names epd" error has changes to "Cannot import name Papirus". I don't understand why this doesn't work, any help would be appreciated

@shawaj All of this was downloaded/trialled yesterday/today, since my screen arrived yesterday.

Do you have a Pi3 to test with?

This is the first I've heard of it not working since we fixed it previously.

When do the errors occur? Ideally need exact steps to reproduce the errors.

Also please try with python 2 instead of python 3.

Unfortunately I don't have a Pi3 to test with. The error occurs after installation, I have entered the following commands and all of them have gone through successfully:

sudo apt-get install python-imaging
git clone https://github.com/PiSupply/PaPiRus.git
cd PaPiRus
sudo python3 setup.py install 

papirus-setup
papirus-set 2.0

Then to test that the package worked, I ran

sudo papirus-clock

and received the following error

Traceback (most recent call):
    File "/usr/local/bin/papirus-clock", line 26, in <module>
        from papirus import Papirus
    File "/usr/local/lib/python3.4/dist-packages/papirus/__init__.py", line 1, in <module>
        from epd import EPD as Papirus
    ImportError: No module named 'epd'

Will try again with python2 and report back, however if you are working on python3 compatibility I would love to be a part of that effort.

EDIT: Reinstalling in Python2 makes papirus-clock work, however testing the screen with my own script doesn't work.

myScript.py

from papirus import Papirus
from papirus import PapirusText

screen = Papirus()

text = PapirusText()
text.write('Top line')
text.write('A little lower', (1,10))

screen.update()

Running this gives me the following error:

sudo python myScript.py

Traceback (most recent call last):
    File "screen_test.py", line 8, in <module>
        text.write('A little lower', (1,10))

I have an old display from the original crowd funding that was working until the last few days when I pulled a Raspbian update that bolluxed my poor 4gb SD card... I haven't found a way to not get the boatload of stuff. Besides the point because I simply started with a bigger SD, pushed the new image... and none of my old code would run. I started looking (aka googling) the problem with /dev/epd/ ... My fix was to stumble on the script bin/papirus-setup which I ran as sudo bash bin/papirus-setup and all my errors stopped, and my old customized clock face popped up again. I got all my Python modules installed for both 2.7 and 3.4... but the missing device took persuasion :-)

Could I please have an update of the issues. The thread is pretty old and things are likely to have been solved. I'd like to close this in two weeks from now if there are no updates. Thanks.
