Setup

• For setting up arduino and LCD display:
  • Verify the script src/arduino/lcd.ino(taken from arduino IDE Examples > SerialDisplay) and upload to your arduino
  • For the hardware setup, follow this video
  • Make sure your data pins match the numbers in the lcd.ino script(not the video)
• Clone and install dependencies:

    git clone https://github.com/ns-xvrn/blocktime.git &&
    cd blocktime &&
    pip install -r requirements.txt

• Setup settings.conf (copy from at same folder location):

    cd src &&
    cp settings.sample.conf settings.conf

• After you connect via USB you will have to set the read/write permissions(use name of your serial device instead of /dev/ttyACM0):

    chmod a+rw /dev/ttyACM0

Run

• The data updates every x minutes as setup in the settings.conf

    python3 blocktime.py console

    python3 blocktime.py lcd

Add aliases (OPTIONAL)

• You can create the following bash script for lcd display (named as bt_to_lcd.sh in below example script):

#!/bin/bash

sudo chmod a+rw /dev/ttyACM0
nohup python3 ~/code/xvrn/blocktime/src/blocktime.py lcd &

• Add aliases in your .bashrc and run source .bashrc:

alias btcmd="python3 ~/code/blocktime/src/blocktime.py console"
alias btlcd="~/code/blocktime/bt_to_lcd.sh"
