Engine Management

I want to start this thing right, so the shopping list for people that want to play along at home:

Raspberry Pi - version is not significant if you don't mind a slow response when using Eclipse, but 3B+ if this is a new set up

- all the stuff to make a RPi a working desktop (SD card, keyboard, mouse, monitor, power supply, and cabling)

- internet connection is also handy, but not mandatory for the workstation after configuration.

Breadboard(s) - the usual kind so outboard components can get attached.

Arduino Nano - this will be the controller platform for the project

Programmer - Pretty much any programmer for AVR that has the 6pin connector

That is pretty much it for the moment, Probably want to get two of the Atmel units. I have a plan to use one as a signal generator for cam and crank signals.

I'll leave the description of initial set up of the Raspberry Pi to the experts, just go through the basic steps to get a version of Raspbian up and running.

Then do the obligatory sudo apt-get update; sudo apt-get -y upgrade step.

Install the AVR components (using the installer type AVR in the search box)

- gcc-avr

- gdb-avr

- avr-libc

- binutils-avr

- avrdude

- debug symbols for avrdude

Next install Eclipse IDE (using the installer type eclipse in the search box)

- Extensible Tool Platform (eclipse)

- C/C++ Development tools for Eclipse (eclipse-cdt)

Last add the AVR plugin to Eclipse. First start Eclipse and agree to the workspace popup. Next go to:

     Help->Install New Software

In the work box, enter: http://avr-eclipse.sourceforge.net/updatesite/ and say Add, and when asked name it AVR and say OK

Next window click the checkbox for the offering and select Next

Keep agreeing with all the boxes, accept the license agreement and finish.

You will need to restart Eclipse when asked.

It might be a good idea to be sure you have a good text editor (this I will leave to you, as text editors are very personal attachments).

It is also a good idea to install a configuration management system like GIT or Mecurial and add the Eclipse plugin (GIT is already on Raspbian).

Once things are up and running, it is always nice to test things out with a "Hello, world!" example.

First start Eclipse, and after it starts, from the menu bar select File->New->Project Then select the type of project, C++ Project and say Next (not Finish)

This is for an AVR project, so in the next window select AVR Cross Target Application->Empty Project name the project appropriately, then say Next (again, not Finish)

Say Next for the debug selections.

Last, select the processor and speed, the processor can be selected from the dropdown, for the Nano, it is an ATMega328p, and the MCU Frequency is 16000000Hz.

Since this is the first project, it will say "Due to selection, it is appropriate to use the C/C++ interface" and "is this OK?"; just agree.

In the icon bar at the top (middle) there is a box with a C on it. This runs the wizard to make a C/C++ file, just remember to include the .c extension.

In the open file, type the usual...

#include <stdio.h>

int main(void) {

     printf("Hello, world!\n");

     return 0;

}

Save the file and build using the little hammer icon in the icon bar.

...hopefully you can now say "Ta Da!"

More to come,
