Dashboard for eink display for periodic speedtest checks.

Eink Display Project

I have a WaveShare 2.13V3 eink hat. I want to use it to display speedtest results.

Eink

Setup for EInk

1. Enable SPI
   1. Run sudo raspi-config
      1. Enable the SPI interface.
   2. Reboot
2. Install the WaveShare EPaper module
   1. git clone https://github.com/waveshare/e-Paper
   2. Navigate into the rasppi folder
   3. sudo python3 setup.py install

Using Eink

import time
from PIL import Image
from waveshare_epd import epd2in13b_V3 as epdriver # Different boards need different imports
black = Image.open("2in13bc-b.bmp")
color = Image.open("2in13bc-ry.bmp")
epd = epdriver.EPD()
epd.init()
epd.Clear()
time.sleep(1)
epd.display(epd.getbuffer(black), epd.getbuffer(color))
epd.sleep()
epd.Dev_exit()

Speedtest

Setup Speedtest

pip3 install speedtest-cli

Using Speedtest

import speedtest
EXPECTED_UP = 100
EXPECTED_DOWN = 100

def get_speedtest() -> tuple:
    test = speedtest.Speedtest()
    test.download()
    test.upload()
    real_up = test.results.upload // 1024**2
    real_down = test.results.download // 1024**2

    percent_up = real_up/EXPECTED_UP
    percent_down = real_down/EXPECTED_DOWN
    return (percent_up, percent_down)

Making Dashboard

Dashboard Psuedocode

# Initialize empty dashboard
# Initialize eink
# Initialize records
# Loop
    # Grab current up/down
    # Update dashboard
    # Update eink
    # Wait
