Simple Nixie Tubes Clock Based on RaspberryPi, adapter and NCS314-6 Tubes or NCS318-6 Tubes shield for Arduino (by GRA and AFCH).

A simple program that show the current time (stored in shield's onboard RTC) at Nixie tubes.

Requared hardware:

1. Raspberry Pi any models with 40-pin GPIO connector (Except A and B models).
2. Arduino to Raspberry Pi adapter (by GRA & AFCH): https://gra-afch.com/catalog/shield-nixie-clock-for-arduino/raspberry-pi-shield-nixie-tubes-clock-ncs314-for-in-14-nixie-tubes-options-tubes-gps-remote-arduino-columns-copy/
3. Arduino Nixie Clock Shield NCS314 (v1.2, v2.x, v3.x) or NCS318: https://gra-afch.com/catalog/shield-nixie-clock-for-arduino/nixie-tubes-clock-arduino-shield-ncs314-for-xussr-in-14-nixie-tubes/

How to use binaries:

1. Download and unzip.

2. Set execute permission "Anyone" to "DisplayNixie" file: https://photos.app.goo.gl/yVWtZkcIU9afhsvI2

3. Enable SPI and I2C modules in the "Raspberry Pi Configuration": https://photos.app.goo.gl/vH7DtG9nwMzJHwvP2 3.1) or CLI way "sudo raspi-config": https://photos.app.goo.gl/wfoPd8CNLSlJ0bF83

4. Run the program "sudo /home/pi/Downloads/NixieClockRaspberryPi-master/Firmware/Debug/DisplayNixie": https://photos.google.com/album/AF1QipPrdCjy8WkSl1f51m8EP9go7VUFAiGsy_bjW9pH/photo/AF1QipPch7Yz6RWZKBhiU_U8SIZtXHFvxyfVzh27Byjp

Сommand line options available for CLITool (/home/pi/Downloads/NixieClockRaspberryPi-master/CLITool/Debug/CLITool):

1. 123456 - any 6 digits. Shield will display these numbers.

2. now - Shield will display current system time at the time the command is executed.

3. clock - the program will loop and will update every second the time from Real Time Clock (RTC on shield board) on tubes.

4. settime x - set time, where x time in format [hh:mm:ss].

5. setsystime - set current time from OS. Example: "sudo /home/pi/Downloads/NixieClockRaspberryPi-master/CLITool/Debug/CLITool 123456" - will show 123456 on tubes.

    To compile the source: 
   

Add folder "DisplayNixie" into the workspace of Eclipse: "File"->"Import", "Genral"->"Existing Project into Workspce". p.s. The project uses the "wiringPi" library: http://wiringpi.com/download-and-install/

    Autorun the program at startup: 

Edit /home/pi/.bashrc file - add string like this: sudo "/home/pi/Documents/Eclipse Projects/DisplayNixie/Debug/DisplayNixie" clock
