Task List - Using Raspberry Pi and 7.5" E-paper Display





Introduction: Task List - Using Raspberry Pi and 7.5" E-paper Display

I wanted to have my tasks list on my desk while i'm working , with some other information like the weather info , a calendar and a prayer times

so I've created this nice project using raspberry pi and e-paper display

so you gonna need :

  1. Raspberry Pi (Zero , Pi 2 , Pi A + , Pi 3)
  2. waveshare 7.5 inch E-paper Display
  3. SD Card
  4. 13x18 cm Photo frame

and here is a video tutorial

Step 1: Connect the HAT to the Raspberry Pi

If you are using Raspberry Pi Zero W , solider the headers and connect the HAT to the pi

but if you are using another version of the Raspberry pi you will connect the HAT directly .

i'm using the raspberry pi zero because it is small form factor and i can fit it in the photo frame

Step 2: Install the Raspbian OS and Transfer the Code

Start by installing the OS to the SD card

and if you need any help please refer to this tutorial

then download the code from here

and then replace the API tokens [Todoist and weather underground APIs] with your own Keys

and then copy the code to you raspberry pi , here i'm using WinSCP

Step 3: Run and Test the Code

from the terminal in Raspberry Pi

navigate to the directory that contains the code and then run "Python cal.py" that will run the project and will display it into the screen

you will need to run the code in the startup of the raspberry pi so please check this article https://www.raspberrypi.org/documentation/linux/us...

Step 4: Finish It !

all the components can fit inside the 13x18 cm photo frame , and you can power it using USB cable

challenge for you is to try to make this project battery powered . i'll try to make a new video with more features and will make it powered by battery

i hope you liked the project

    I downloaded the Task - Raspberry Pi.zip and it seems to be missing some of the files. Specifically the cal.py.

    Can you point me to a copy of the file? I've tried to recreate it from the video, but I don't believe the full code is shown.

    Thank you.


    very nice project. I've had pretty much the same idea a few months ago, so I started with my own. I also used the waveshare display with 7.5". But I ran into trouble when (after a couple weeks and several picture updates on the display) the display started to look pale and washed out but only with certain pictures. So I tried refreshing it by setting it into a black screen for a while. But it didn't help.

    Do you have the same problem? If so what did you do about it?

    I am looking forward to your response :)

    familian error?

    Question 5 months ago

    do you have full command list what i need to install etc. I have clean raspberry pi zero w with rasbian lite. i try earlier and error is no module named EPD_driver

    I got this error: File "cal_tasks.py", line 178, in displayTasks
    KeyError: 'snow'
    seems that something is wrong with your fonts. Could you please help me?


    I am trying to do a similar project with this display and rasberry PI 3 ... I am trying to make it so I can connect via USB or possibly by Ethernet and send a graphic image like a BMP and display the image on the E-Paper display but I do not have your programming expertise. I am struggling with this programming and with the best method of sending the images to the rasberry device. Thank you for any helpful advice or resources you can provide and thank you for posting this project!

    I'd like to modify this to work from a local task manager (todo.txt or taskwarrior) instead of todoist. Did you work from an example or sample code from waveshare to develop these screens? Do you have any additional documentation or code up on github that I could look at to learn how it works?

    you can add the Tasks in a json format like the todoist , and use the same code

    i'll add the code to Git Hub repo when i finish more code , because i broke my screen and need a new one

    Hi Hamedtaha,

    I like this project and want to access the project in Git Hub when you update the code.

    Please share how to access Git Hun when it is ready.

    do you know if the e-paper driver supports the 3-colour version that is the only one that seems to be sold now? (it also has red as well as B/W)

    on Amazon.de the page for the 3 colors , i see a review that it didn't workwell with Arduino , but it works fine with Raspberry pi .

    I didn't try it myself but that was a trusted comment.

    Before you post a member, I had this e-ink display ordered. :)

    I'm planning to implement a caldav client (for connect to Google Calendar) and a web interface for connection setup over wifi hotspot.

    i think E-paper is a perfect display for such a project

    Could you keep us informed of your progress?
    I would love to built an e-ink display family calender too :-)

    this will be my second step , to have a family shared calendar . when i buy new screen i'll go on with the development
