# Python v3.4.2 console based script
# Set Raspberry Pi GPIO ports Low depending on user input
# User enters number between 0 and 15, GPIO ports 22, 23, 24 & 25
# are set as BCD representations of the decimal input.
# GPIO ports are weighted 0, 2, 4, 8 [GPIO 22, 23, 24, 25]
# Number 99 entered quits the script
# GPIO ports connect to AD8-11 ports on HT12E encoder chip
# user input is BCD coded & used to set AD8-11 ports
# GPIO port 17 is used to send trigger pulse to activate the HT12E for 1 complete cycle

Coding Conventions

This file will cover important coding practices that are important to stress when coding this program. Listed below are some of the more important details that should be stressed. Each programmer has his/her own way to deliver code. The importance of having similar coding conventions throughout this program are listed below.

• 80% of the time spent on a piece of software goes to maintenance.
• Hardly any software is maintained for its whole life by the original author.
• Code conventions improve the readability of the software, allowing engineers to understand new code more quickly and thoroughly.
• If you ship your source code as a product, you need to make sure it is as well packaged and clean as any other product you create.
