Glasgow CAN Interface Addon

This repository provides the hardware and software components of a CAN Interface Add-On for the Glasgow Digital Interface Explorer.

A rough spec is outlined below:

• Sits alongside a Glasgow board
• 2x CAN interfaces, available on a single port
• Standard DE-9 connectors
  • Default pinout is suitable for use with existing CAN and OBD-II adapter cables (on CAN1 and CAN2 repsectively)
  • Can be easily rewired by cutting jumpers
• Spring-loaded terminal blocks for ease-of-use
• Indicator LEDs for Tx and Rx
• Software configurable 120Ω termination, with state LED
• ESD protection
• CAN FD support in hardware (software to follow)

Future plans:

• Isolation between each CAN port and the Glasgow (and host)

Out-of-Tree support will be required when work on the applet begins (see PR #213).
