Raspberry Pi Nixie Tube Driver library

This Raspberry Pi LED and Nixie Tube driver library is for the board from this kickstarter: https://www.kickstarter.com/projects/36162341/raspberry-pi-nixie-tube-driver

This library usable in code as follows:

import raspberrypinixie

try:
    raspberrypinixie.setup()

    # Your code here

finally:
    raspberrypinixie.cleanup()

Example operations are:

# Turn all LED on
raspberrypinixie.led_set(True, True, True, True ,True ,True)

# Set Nixie tubes
raspberrypinixie.nixie_set(1, 2, 3, 4 ,5 ,6)

# Turn only the middle 2 LED on
raspberrypinixie.led_set(led3=True, led4=True)

# Turn only the middle 2 Nixie Tube on
raspberrypinixie.nixie_set(nixie3=9, nixie4=0)

# Turn all LED off
raspberrypinixie.led_set()

# Turn Nixie tubes off
raspberrypinixie.nixie_set()

This repository was created by measuring the signals on the PCB when each Raspberry Pi pin was asserted.

This repository also contains a couple of sample programs using the library as follows:

Auto test program

The Auto test program will cycle every nixie tube from 0 to 9 once a second (by default) as well as turn each led off and on one by one.

# The library module can be executed to start the Auto test program:
sudo python raspberrypinixie.py

# The Auto test program can also turn Nixie tubes off in the cycle:
sudo python raspberrypinixie.py --nixie-off-test

# The cycle speed and led behavior can be changed via these options
sudo python raspberrypinixie.py --delay 0.1 --led-mode ON

# To see additional options:
python raspberrypinixie.py --help

Basic clock program

The clock program is a 24 hour clock that uses all Nixie tubes as digits and has options on whether to strobe the LED, keep them all ON or all OFF.

# To run the clock program:
sudo python samples/clock.py

# To see clock program options:
python samples/clock.py --help

# Run the clock program with UTC time offset and an always on LED
sudo python samples/clock.py --hour-offset -7 --led-mode ON

Weather clock program

The Weather clock program uses the first 2 Nixie tube as the temperature at the specified location. The first LED will be on when the temperature is less than 0 and the second LED will be on when the temperature is greater than 99.

Note: The Weather clock program will connect to MetaWeather.com to get the temperature, and requires Python3 for https TLS 1.2 support

# To run the weather clock program:
sudo python3 samples/weather-clock.py "San%20Francisco"

# Display the temperature in Fahrenheit and UTC time offset:
sudo python3 samples/weather-clock.py "San%20Francisco" --fahrenheit --hour-offset -7

Direct LED and Nixie controller

The LED set and Nixie set program directly sets the LED or Nixie tubes respectively. They will turn off any LEDs or Nixie tubes not specified in the execution.

# Turn on LED1, LED3 and LED6
sudo python samples/led_set.py --led1 --led3 --led6

# Set Nixie tube 2 to 1, Nixie tube 4 to 2, and Nixie tube 5 to 3
sudo python samples/nixie_set.py --nixie2=1 --nixie4=2 --nixie5=3

# Turn all LED off
sudo python samples/led_set.py

# Turn all Nixie tube off
sudo python samples/nixie_set.py
