inky-cryptochart

CLI tool to display cryptocurrency candlestick chart on Pimoroni Inky pHAT or Waveshare 2.13inch E-Ink display HAT

04b03 freeware font by 04.

Setup

Install the inky-phat prerequisites (see official instructions):

sudo apt-get install python3-pip python3-dev

Wavehsare

The Waveshare HAT requires an extra step since it has a slightly different pinout. You can redifine the pins on the inky212x104 module:

-RESET_PIN = 27
+RESET_PIN = 17
-BUSY_PIN = 17
+BUSY_PIN = 24
-DC_PIN = 22
+DC_PIN = 25

Usage

usage: cryptochart.py [-h] [--pair PAIR] [--flip] [--output OUTPUT]

optional arguments:
  -h, --help       show this help message and exit
  --pair PAIR      currency pair (default: XETHZUSD)
  --flip           rotate the display (default: False)
  --output OUTPUT  save plot as png (default: None)

Configure crontab

Use crontab -e to add run the cronjob every 15 minutes:

*/15 * * * * (cd /home/user/inky-cryptochart; python3 cryptochart.py --pair XETHZUSD --flip)

If you are not familiar with cron, have a look at the excellent CronHowto wiki to configure it according to your requirements.
