Python Nixie Clock (+ ESP32/MicroPython)

Python code to drive Nixie smart sockets

VERY MUCH DEV IN PROGRESS!!!!!

What works

• ONLY can drive smart sockets at the moment.
• Gets time and date biased off Geo located IP.
• Supports ESP32 and local Linux serial port modes (can be driven from a serial port under linux or burnt into MicroPython F/W)

Whats not working (but will oneday)

• Direct drive of any non smart socket nixie tube
• Way to much is hard coded
• H/V shutdown
• Smart socket tube setting / per tube / at all
• Reading temp/humidity sensors

Whats hard coded...

• Machine UART pin number
• Serial device for PC/linux mode
• Time format 12/24h
• Date format (range of types supported)
• What to do on 10/15/3060min window intervals
• What time the intervals are

Tests

Basic tests are written, but needs more. Coverage is around 60% so pretty low at the moment.
You can run tests via:

tox

How to build

NOTE this is ONLY needed for ESP32 mode.
Uses Earthly.dev to build the latests MicroPython F/W based on a set tag of the Espressif framework.

Build firmware

earthly +firmware   

Program ESP32

earthly --build-arg SERIAL_PORT=/dev/ttyUSB0 +flash   

** Where /dev/ttyUSB is your ESP32 device.

Example main.py

import wifi_setup
import clock
wifi_setup = wifi_setup.WIFI_setup('AP_SSID','YOUR_PASSWORD')
wifi_setup.connect()

# Run in 24 Hour mode, with 6 sockets and date format of DD-MM-YY on an ESP32 device.   
# Breakdown of the function: clock.MainLoop(DEVICE TYPE, SOCKET COUNT, TIME FORMAT, DATE FORMAT, SERIAL DEVICE)
run = clock.MainLoop('micropython','6','24h', 'DDMMYY', 'micropython')
run.main()

Local Linux mode

Set up your serial device and time preferences in the code and run modules/clock.py.

External dependence's

• Smart sockets
• If using Micropython ( All from https://github.com/micropython/micropython-lib )
  • urequests (provided in this repo)
  • datetime (provided in this repo)
  • wifi_setup (provided in this repo)
  • Eathfile, (provided in this repo) [Only Needed for Micro Python]
  • Tox Only needed to run tests
