Comvette Ready-To-Run Raspberry Pi Image File

Download this ready-to-run image file to try Comvette on your Raspberry Pi. Once you have downloaded the image file, you will need to use an imaging tool such as HDD Raw Copy Tool (or similar) to place the image on your Raspberry Pi's memory card. A 32 Gigabyte memory card or larger is recommended.

Xojo

Xojo is a cross-platform, object oriented, rapid application development environment. It is easy to learn and can be downloaded and used for free.

Xojo was chosen for this project because of its user friendliness and its ability to easily create complex graphical user interfaces and its ability to create native executables for the Raspberry Pi.

With the free "Xojo Pi" license, you can create compiled stand-alone executable programs for your Raspberry Pi. Just download Xojo and then Email Xojo to request your free Xojo Pi license (links below).

Comvette 160 Baud ALDL Reader Sketch

An Arduino sketch to read the 160 Baud ALDL data stream. This sketch reads the 160 Baud ALDL data stream from the ECM, translates it into a string of ASCII 1's and 0's and then sends the string to an RS232 host at a standard Baud rate.

This was my first attempt at reading ECM data. It did prove that the Arduino is capable of monitoring the ECM data line in real-time. The 160 Baud ALDL data stream does not contain as much data as the 8192 Baud data stream but it does contain a lot of useful diagnostic data.
