learning Ada

Learning about: GNAT toolchain from the GNAT Community 18 edition,
project manager (GPRbuild)
integrated development environment (GNAT Programming Studio).

Dividing this restarted project into two parts:
1. installing the toolchain and
2. sample source code

default install directories:
~/opt/GNAT/2019/bin $ [ try ./gpr ]
checkout [sudo ./doinstall] and

gps will be installed in [/opt/gps]

~/Ada_Drivers_Library/scripts $ ./project_wizard.py

Some rules when connecting devices (modules) like sensors: with special attention to serial busses like i2c.
This is the start of a guide to show how to build circuits with multiple types of sub assemblies.
It also documents the thought processes in connecting a Raspberry Pi to external sensors. The sensors are on a standalone board and operate

from different voltages. Work is happening to interface the BBC micro:bit, Cypress boards and Arduinos.
The i2c protocol requires the SDA and SCL lines to be bidirectional (i.e. input and output)

Blink
The basic Energia example.
Turns on an LED on for one second, then off for one second, repeatedly.
Change the LED define to blink other LEDs.

Hardware Required:
LaunchPad with an LED

This example code is in the public domain.
