Collection of CAN bus packages and tools

This document assumes the use of Linux as the chosen development platform. Items in bold are highly recommended.

It is recommended to use SocketCAN when working with CAN bus on Linux. It is supported by the Linux kernel mainline and follows the Linux interface model, allowing you to use other network tools such as Wireshark. This also allows the creation of virtual CAN interfaces where no physical hardware is required to simulate or replay CAN messages.

Postgres Cheatsheet

This is a collection of the most common commands I run while administering Postgres databases. The variables shown between the open and closed tags, "<" and ">", should be replaced with a name you choose. Postgres has multiple shortcut functions, starting with a forward slash, "". Any SQL command that is not a shortcut, must end with a semicolon, ";". You can use the keyboard UP and DOWN keys to scroll the history of previous commands you've run.

Setup

installation, Ubuntu
